Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your vehicle does when it is new. When you replace parts of your braking system - for example, when your brake linings wear down and you have to have new ones put in - be sure you get new genuine GM replacement parts. If you don't, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change, forthe worse. The braking performance you've come to expect can change in many other ways if someone puts in the wrong replacement brake parts.

Your maintenance schedule will tell you how often this must. bedone. Front Shock Absorbers The front shock absorbers of your vehicle do many things. They help the vehicle ride smoothly and also control the travel of the suspension system. When the shock absorbers are serviced, any replacement shock absorbers must be the same as the original equipment shock absorbers in both extended length and strength. NOTICE: If you use shock absorbers that are not the same original as the shock absorbers, the shock absorbers or suspension system could be damaged. 6-46
