Disc Brake System Testing

2004 Oldsmobile Bravada AWDSECTION Disc Brake System Testing
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The numbers below refer to the step numbers on the diagnostic table:
  1. 9  - Lubricant leaks from non-brake system components may come in contact with and contaminate brake system components.
  2. 10  - Lubricant leaks from non-brake system components may come in contact with and contaminate brake system components.
  3. 12  - Disc brake rotor shields/backing plates that come in contact with disc brake rotors may cause brake system noise.
  1. Were you sent here from a Brake Symptom Test or Table? If so, go to next step. If not, go to DIAGNOSTIC STARTING POINT - HYDRAULIC BRAKES  under TROUBLE SHOOTING.
  2. Visually inspect the disc brake pads for the following:
    • Lining thickness uneven and/or abnormal wear (edge-to-edge and/or side-to-side).
    • Evidence of contamination from an external substance Looseness or damage (including pad hardware).
    Did you find any conditions to indicate a concern with any of the (front and/or rear) disc brake pads? If so, go to next step. If not, go to step  12 .
  3. Are any of the (front and/or rear) disc brake pads contaminated? If so, go to step  8 . If not, go to next step.
  4. Are any of the (front and/or rear) disc brake pads worn unevenly? If so, go to step  7 . If not, go to next step.
  5. Are any of the (front and/or rear) disc brake pads and/or pad hardware loose or damaged? If so, go to step  7 . If not, go to next step.
  6. Remove and inspect the worn disc brake pads for glazing, looseness, heat spots or damage. Replace the worn disc brake pads as a complete axle set. See FRONT BRAKE PADS  under REMOVAL & INSTALLATION. After repairs are complete, go to step  12 .
    7. CAUTION: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
