The SteelLite X30 brake drum sets a new standard in advanced wheel-end design and development. Feature for feature, our SteelLite X30 brake drum is a superior alternative to any other brake drum available. Advanced Fleets who specify the SteelLite X30 brake drum for medium- and heavy-duty trucks, tractors and trailers will enjoy its considerable advantages, including reliability, balance, weight reduction and lifetime operating cost. The forming process we use to develop the SteelLite X30 brake drum produces a one-piece steel shell that provides exceptional strength, durability and concentricity. This design eliminates the need for a weld seam, which can compromise strength or produce weldinduced hard spotting. Our brake drums are also accurately and permanently balanced without weld weights. The one-piece steel shell and cast iron braking surface also provide substantial weight savings over standard full-cast Lightweight iron drums. In fact, total weight reduction on a typical tandem axle tractor/trailer combination equipped with the SteelLite X30 brake drum can be as much as 200 pounds! Our centrifugal casting process permanently fuses gray iron braking surface material to the one-piece steel shell. If the braking surface should ever crack due to heat checking, the outer SteelLite X30 steel shell can help prevent debris from littering the highway. 2

Exclusive One-Piece Steel Shell. Provides exceptional strength, durability and concentricity, and reduces weight. One-piece design eliminates weld seams. Lighter Weight.

HOW TO USE THIS CATALOG The Meritor part numbering system divides as such; Example: 03-122222 - 002 Prefix Base Number Suffix The prefix indicates the part type. The 03 in the example indicates a cast non-balanced brake drum. The 31 different prefix numbers are used to categorize and describe the part. At present not all of the prefix codes are currently being used, but all are listed for your reference. (See attached Prefix Chart) This drum, rotor and trailer hub catalog covers prefix codes 03, 04, 13, 14, 23, 53, 83, 85, 93, 95. 122222 base number, when coupled with the prefix, gives the part type and the part dimensional specifications through the numerical part number listing. The base numbers are not all available with all the prefix combinations. The suffix, a three digit number, indicates the phase of manufacturing the part is in. For the current list of Meritor Brake Drum and Rotor part numbers, see the appropriate numerical listing.

WHAT MAKES A GOOD BRAKE DRUM There are a number of attributes that differentiate between mediocre and a good brake drum. The following highlights these and what they mean to the end user. 1. A HEAT ABSORPTION DEVICE (HEAT SINK). The braking system in a vehicle converts the vehicle energy of motion into heat energy by means of friction between the brake lining and the brake surface of the brake drum when the vehicle s brakes are applied. a). The surrounding parts, such as brake lining, rim, tire, hub, bearings, and drum absorb heat by conduction and radiation. b). The surrounding air is heated by convection. Radiated heat to surrounding parts is small and heat dissipated by convection to the surrounding air is slow relative to the actual time of braking. For these reasons nearly all the braking energy must be stored in the form of heat in the brake drum. This energy is stored by heating the drum material to a higher temperature than the drum temperature prior to the brake application. A heavier drum will store more energy than a light one will. A heavier drum is stronger and more fade resistant. 2. A CYLINDRICAL BRAKE LINING INTERFACE. The brake drum moves past a stationary brake lining. When (if) the brake surface does not move past the lining uniformly, the brake drum has run out. This will overstress the drake drum, linings, and attaching hardware, causing variable heating of the brake drum braking surface which results in heat checking, excessive wear of both the drum and lining, pulsing of the brake, and shortened life of both the drum and lining. Also to keep the drum dimensionally stable under these conditions, it must be a relatively heavy brake drum. A heavy precise brake drum does not reduce the need for linings to fit the drum correctly. If the linings are not contoured to fit properly, the brake will not produce proper breaking torque. Poorly contoured linings cause additional mechanical stress in the drum, shoes and lining, and brake hardware. This additional stress hastens failure and greater wear. Before linings are burnished or seated into the brake drum, they may rub on only a few high spots. These superheat the brake drum braking surface in very small areas and can be seen on the brake dynamometer as fire bands. A light brake application will cause this to occur whereas a snub brake application will force the lining against more of the braking surface of the brake drum thus limiting or even eliminating these types of hot spots. If these hot spots are allowed to continue, martensite hot spots will occur, and in turn drum distortion, and very early cracking can happen. Lining that takes longer to burnish will be more likely to cause hot spotting. Many of the non-asbestos organic linings fall into this category. Since martensite hot spotted brake drums cannot usually be successfully rebored, they usually must be scraped. 3. HIGH STRENGTH, HEAT, AND WEAR RESISTANT BRAKE DRUM MATERIAL. A brake drum must be strong enough to resist the maximum mechanical stress caused by the expanding and selfenergized brake shoes at high temperatures. The brake drum s stiffness or resistance to deflection is derived from the thick shell structure and the stiffness of the gray cast iron. Higher tensile strength gray iron does not change the deflection of the brake drum significantly. Although higher strength iron is more resistance to thermal stress caused by temperature gradients, as a hot brake surface and a cold outside brake drum diameter. The occurring problem here is the cold outside diameter of the brake drum does not want to expand to a bigger diameter, but the hot inside diameter of the brake drum does want to expand. The hot inner surface is caused to compress or compresses plastically so that it fits within the cold outer surface. But as the hot inner surface cools, cracks form because the metal was too compressed to return to its original position thus resulting in hairline surface cracks known as heat checks. Per SAE J431, recommended strength of a heavy-duty brake drum iron is 35,000 psi. The Meritor brake drum iron strength is determined from test bars cut from brake drums rather than separately cast test bars, and averages over 40,000 psi. It is important to realize/note that as the strength of the brake drum increases so does their resistance to wear. 4. HEAVY ROTATING PARTS THAT IF IMBALANCED CAN SIGNIFICANTLY AFFECT THE VEHICLES RIDE. The mass of a 16.5" x 7" brake drum is concentrated about 9 inches radially from the hub bearing centerline. Unless the brake drum is balanced, it helps excite vibration in trucks and trailers. That is why it is important to use balanced brake drums on all front and rear applications. Most brake drum balancing is done by welding weights to the outside of the drum, but Meritor pioneered and patented a technique to balance brake drums without welding on balance weights this is called Machine to Balance (MTB). The industry typically requires front hub/drum assemblies balanced to 20-in. oz. maximum and rear hub/drum assemblies balanced to 50-in. oz. maximum. 5

WHAT MAKES A GOOD BRAKE DRUM (Cont d.) 5. SUMMARY; THE BEST BRAKE DRUM FOR OVERALL PERFORMANCE Is a relatively heavy brake drum Is made from temperature and wear resistant high tensile iron Is precisely machined Is balanced by machining rather than adding weights MAXIMUM BRAKE FACE DIAMETERS Maximum brake face diameters are indicated on Meritor Brake drums, i.e., the word Max.Dia. 15.120 inches 384.05mm will be found on brake drums with a 15 inch, 381mm nominal brake face diameter. This means that for safe operation the brake face diameter should never exceed 15.120 inches, 384.05mm from machining or wear. Because we have no way of knowing the number of heat cycles or the severity of the cycles to which the drum has been subjected in actual usage, we do not recommend reboring the brake face diameter. The user is best able to judge whether the drum has sufficient life remaining to justify reboring. The maximum diameters are shown in the chart. Meritor has engineered their brake drums to provide safe operation At the maximum brake face diameters, however, Meritor does not machine these drums to maximum diameters and cannot control the methods that others use to re-machine them after they are put into use. Do not confuse maximum brake face with maximum rebore diameters. When the drum reaches the maximum brake face diameter, it must be removed from service. There may be some instances where it is a good economic decision to rebore a brake drum but after rebore, there must be some wear life left (at least.040 inches) prior to reaching discard diameter. Meritor does not recommend reboring brake drums for the following reasons: 1. It usually is not a good economic solution, 2. Reboring does not remove fatigue damage even though it may remove the heat checks. 3. It is very difficult to avoid running brake drums over the maximum brake face diameter. 4. Martensite (hot spots) and distortion caused by it are virtually impossible to remove. 5. Severe corrosion is frequently on the outside of the drum which weakens the drum. NOMINAL DIA.

WHAT MAKES A GOOD BRAKE DRUM (Cont d.) WHEN SHOULD A BRAKE DRUM BE REPLACED? The ability of a brake drum to perform safely is affected by a variety of factors. Conditions, which affect the life of brake drums, are listed, although this list is not intended to be all-inclusive it should serve as a useful guide. The brake drum should be replaced when any of these conditions appear. 1. Brake face diameter reaches maximum limit 2. Excessive heat checks 3. Cracks 4. Martensite spotted drums hot spots 5. Worn or elongated bolt holes 6. Galling of brake surface 7. Brake drum known to have been overheated as occurs with dragging brakes 8. Brake drum warped.out of round 9. It may be necessary to replace brake drums in pairs in order to maintain proper brake balance and efficiency. RECOMMENDATIONS FOR LONGER BRAKE DRUM AND ROTOR LIFE When drums are forced to fit onto a hub, there is improper match of parts for installation. The cause must be determined and corrected. Wheel bearings should be properly adjusted to prevent the drum from picking up the load created by the braking action Drums and linings should be checked at periodic intervals to detect operational patterns. The use of non-asbestos organic linings can cause linings to swell and drag resulting in hot spots and lower fuel economy. Clearance between non-applied brake linings and the drum varies slightly. See the brake system manufacturer s recommendations for this adjustment. Proper clearance prevents excessively hot linings and drums and improves fuel economy. Parking brakes should not be set while the drums are hot. Allow them to cool, otherwise, drum cracking and failure can result. DRUM FAILURE ANALYSIS Regular and thorough inspection of your brake system is the best investment you can make for low cost per mile brake operation. Be sure you have a standard inspection timetable and follow it. The following pages list common problems you should be alert for. 7

COMMON PROBLEMS Grease Stained Drums Brake drums with discolored spots on the braking surface, and oil or grease splattered on the brake assembly indicates over-lubrication of the cam or camshaft, or by an oil seal failure. Correct this problem by repairing the source of the oil or grease leak, clean the drum and replace soaked linings. Cracked Drums A drum which has cracked completely through a section of the braking surface must be replaced immediately. A cracked drum is not repairable! Cracked drums are caused by one or more of the following: 1. Excessive heating and cooling 2. Excessive shoe pressure Repeated cracking of this type may indicate one or more of the following: 1. Dragging brakes 2. Inadequately designed drums for the application 3. Inadequately designed braking system for the application 4. Incorrect brake balance of the vehicle 5. Driver abuse The total braking system of the vehicle should be checked thoroughly, paying attention to the following: 1. Proper friction ratings 2. Proper valving and pluming 3. Proper brake balance 4. Missing linings and/or brake system components. Heat Checking A broken network of fine hairline cracks on the braking surface of the drum, is a normal phenomenon of braking surfaces. It is caused by regular heating and cooling of the surface. Heat checking does not impair brake performance; but you should examine heat checks frequently to make sure they have not grown deep enough to weaken the drum. Oversized Drums If the brake surface diameter is in excess of it s specified maximum diameter, replace the drum immediately. It may be necessary to replace drums in pairs to assure proper brake drum balance and braking efficiency. If the linings show irregular wear replace them. 8

COMMON PROBLEMS (Cont d.) Scored Drums Scored drums are signified by circumferential grooves on the braking surface and excessive lining wear. If the scoring is not deeper than the maximum rebore diameter, the drum may be rebored and returned to service. The linings should be replaced and the braking system should be checked to make sure excessive amounts of abrasive material are not entering into the lining-drum contact area. If the scoring is deeper than the maximum rebore diameter, replace the drum immediately. Out-Of-Round Drums Variations in drum diameter at different points on the braking surface indicate out-of-round drums. The drum should be machined within allowable rebore limits to restore concentricity. Do not exceed the maximum rebore limit of turned drums, and replace drums which are worn beyond their specified maximum diameter. If you are unable to restore concentricity by reboring the drum, replace it with a new one. It may be necessary to replace drums in pairs to assure proper brake drum balance and braking efficiency. Excessive Wear and Galling Excessive wear along the edges of the lining contact area, or in areas coinciding with the rivet holes of the lining, is usually caused by abrasive material collecting between the lining and the drum/rotor. Remove the abrasive material from the system and check the drum for scoring. If the brake drum is scored beyond the maximum limit, replace the drum immediately. Install dust shields to restrict the amount of abrasive material which can enter the braking system. Excessive wear can also be caused by misaligned brake shoes. If the shoes are not square to the braking surface, uneven forces are applied. This can result in deep grooves in the braking surface. If the brake drum is scored beyond the maximum limit, replace the drum immediately. Correct the brake shoe alignment to alleviate further grooving. Brake drum galling in an abnormal wear pattern is due to initial incompatibility between the brake drum lining and the brake surface. This condition may correct itself due to brake drum and lining wear. If severe, consider replacing the lining and/or the brake drum. 9

COMMON PROBLEMS (Cont d.) Blue Drums A bluish disfiguration on the brake parts (shoes, drums/rotors or bolts) indicates excessive heat. This is usually caused by an oversized brake surface diameter/undersized rotor width or by weak or broken return springs. For drums, check the braking surface diameter. If it is oversized, replace the drum immediately. If the return springs are weak or broken, replace them. Martensite Spotted Drums Martensite spotted drums have extremely hard, slightly raised, dark colored spots on the braking surface, shown uneven wear and the surface is out-of-round. This condition may cause excessive noise or shudder during brake applications. Unless this is detected very early, the brake drum should be scrapped. The spots are caused by very light brake applications with nonasbestos organic linings that are contacting the drum at a few lining high spots. To avoid this problem, change braking technique to snubs rather than light dragging stops or ensure the lining fits the drum contour uniformly when it is new. Attempts to rebore a drum to remove the spots will usually aggravate an already bad situation, and if the drum is allowed to stay in service, cracks will connect between the martensite spots leading to brake drum failure. If the brake lining and drum are replaced and the same brake application techniques are used, the results will likely be the same. If only the drum is replaced it may not develop these spots (as the high points are worn down). Polished Drums A polished brake drum/rotor is characterized by a mirror-like finish on its braking surface. Correct this problem by removing the gloss with 80 grit emery cloth. If the problem recurs, check the linings to make sure they are the proper friction rating. If the linings are glazed, consult the vehicle manufacturer for the proper lining material. 10
