There are a number of checks you can do, and you may be able to do some of the service work yourself. But please: let your dealer’s service department do any work you don’t have the tools or skill to perform. Authorized service mechanics are trained in the proper technical and safety procedures to fix your Peterbilt vehicle right. Brake Adjustment WARNING! To prevent uncontrolled vehicle movement and reduce risk of personal injury, park the vehicle on a hard level surface, apply the parking brake, and chock all wheels securely. To operate your vehicle safely and profitably, you need some understanding of its brake systems. For more on brakes, see the Index, under Brakes. Brake adjustment and brake balance must be set carefully to (1) make the most efficient use of the forces available for braking and (2) allow equal stopping forces at all wheels. WARNING! It is dangerous to work on a vehicle without the right know-how and proper tools. – 146 – Y53-6015 R(08/07)
PART 8: MAINTENANCE AND SERVICE Brake Adjustment CAUTION: The air brake system of this vehicle was configured for ONE of the following operations: tractor or truck, and complies with the respective portions of FMVSS 121. A tractor shall not be operated or configured as a truck, nor shall a truck be operated or configured as a tractor, without significant modifications to the air brake system in order to retain compliance with FMVSS 121. Contact your Peterbilt dealer for instructions. Once a brake system is set to specifications, changing any one of its components or any combination of components may cause the system to not work as well. All parts have to work together to perform as they should. Any replacement components in your brake system should be exactly equal to the original components. Any changes from the original specifications can affect the whole system. All of the following areas are interrelated and must conform to original specifications: • Tire Size • Drum brakes A. Cam Radius B. Wedge Angle C. Drum Radius D. Brake Linings E. Brake Chambers F. Slack Adjusters WARNING! A nonconforming part in your brake system could cause an accident. Sizes and types are so related to one another that a seemingly unimportant change in one may result in a change in how well your brakes work for you on the road. If parts don’t work together properly, you could lose control of your vehicle. Be sure any replacement parts in your brake system conform exactly to original specifications. All vehicle operators should check their brakes regularly. Always adjust your brakes when they are cool. WARNING! Brake linings and pads with a thickness below the specified minimum will have exposed rivets. Use of such linings can damage the braking surface and also reduce brake efficiency, which could cause an accident or system failure. R(08/07) Y53-6015 – 147 –
