Brake Pads
NOTE: It is not required to install new brake pads when the brake discs are machined.
1. Inspect the brake pad friction material for contamination.
-
If the friction material shows evidence of contamination, install new brake pads.
2. Inspect and measure the thickness of the brake pad friction material. For additional information, refer to Specifications.
-
Minor surface cracks do not require pad replacement, however, if there are missing chunks or cracks in the lining through to the backing plate,
install new brake pads.
-
If the thickness of the friction material is less than the specified thickness, install new brake pads.
-
If the friction material shows taper wear that is not within specifications, install new brake pads and verify the caliper guide pins are
functioning correctly. For additional information, refer to Brake Caliper Guide Pins inspection. See: Testing and Inspection/Component Tests
and General Diagnostics/Brake System Inspection/Brake Caliper Guide Pins
Brake Discs
Brake System Inspection
Brake Discs
NOTICE: Using an impact tool without a torque socket will lead to unevenly tightened wheel nuts. This causes brake disc on-vehicle lateral
runout and brake roughness.
1. Inspect the brake discs and measure the brake disc thickness in a minimum of 4 places around the circumference of the brake disc. Record the
measurements, refer to Specifications.
-
If the brake disc is cracked or otherwise damaged, install a new brake disc.
-
If any measurement is below the minimum thickness specification, install a new brake disc.
-
If the diagnosis has revealed vibration in the steering wheel, seat or pedal while braking that varies with vehicle speed, machine the brake disc.
Heavily scored brake discs, similar to that caused by pads worn down to the backing plate, should also be machined. In order to machine, discs
must be above the minimum thickness specification. For additional information, refer to Specifications and Brake Disc Machining See: Disc
