Function & Signs of Wear

Brake Pads:
Function: Flat pads with frictional materials contact the rotor to help slow or stop the vehicle (disc brakes)
Signs Of Wear: Chirping, grinding or squealing noise, difficulty stopping the vehicle
Did You Know?
When you step on your brake pedal, you command a stopping force 10 times as powerful as the force that puts the car in motion. The brakes system can exert as much as 1,000 pounds (450 kg) of hydraulic pressure on each of the four brakes.
What It Does
The Brakes System applies frictional force to the wheels to slow or stop the vehicle.
Service & Maintenance
The following inspections and maintenance procedures can help prevent potential brake problems:
- Check brake fluid level at every oil change. Replace fluid according to Owner's Manual recommendations.
- Calipers and wheel cylinders should be checked every brake inspection and serviced or replaced as required.
- Inspect the brake lines for rust, punctures or visible leaks (you may be able to do this, but consult a qualified technician if necessary)
- The following should be conducted by a qualified technician:
Inspection of the brake hoses for brittleness or cracking. Inspection of brake lining and pads for wear or contamination by brake fluid or grease. Inspection of wheel bearings and grease seals. Parking brake adjustments (as needed). New DuraStop rotors DO NOT need machining. - Used rotors can be machined provided minimum thickness can be maintained:
Before you machine rotors, make sure the lathe is clean, within specs and has sharp tool bits. After completing the finish cut, sand both sides of the rotor for one minute per side using a sanding block and 130- to 150-grit sandpaper to obtain a non-directional finish. After sanding, wash the rotor with dish soap and water. DO NOT clean the rotor with brake cleaner/solvent-based product. - Thoroughly clean the calipers, caliper slides and hardware. Remove all dirt, rust and grease.
Lubricate caliper slides, shims and rubber components.
Use ACDelco silicone-based lubricant or equivalent before installation. ACDelcolubricant is rated at 2,000F.
DO NOT use a petroleum-based or spray adhesive product:
Lubricate all hardware rubber components and all metal-to-metal contact points
Give caliper slides and disc pad shims/insulators a thin film of lubricant. This will allow the shim to withstand normal brake pad movement without damage to the shim. Additionally, this helps dampen vibration. Make sure the disc pads are tight in the caliper and torque the caliper to the housing. Check the adjustment of the rear brakes. Adjust if necessary. After cleaning all wheel-hub mating surfaces, install the wheels. Make sure they are torqued to manufacturer's specifications.
