Preliminary Brake Check
- Check the condition of the tires and wheels. Damaged wheels and worn, damaged, or underinflated tires can cause pull, shudder, vibration, and a condition similar to grab.
- If the complaint was based on noise while braking, inspect the suspension components. Jounce the front and rear of the vehicle and listen for noise that might be caused by loose, worn or damaged suspension or steering components.
- Inspect the brake fluid level and condition. Note that the brake reservoir fluid level will decrease in proportion to normal lining wear. Also note that brake fluid tends to darken over time. This is normal and should not be mistaken for contamination.
- If the fluid level is abnormally low, look for evidence of leaks.
- If the fluid appears contaminated, drain out a sample to examine. System will have to be flushed if fluid is separated into layers, or contains a substance other than brake fluid. The brake system will require replacement of all components which have rubber parts. Use clean brake fluid to flush the system.
- Check the parking brake operation. Verify full release of both side rear brake calipers.
- Check the brake pedal operation. Verify that pedal does not bind and has adequate free play. If the pedal lacks free play, check the pedal and the brake booster for being loose or for bind condition. Do not road test until condition is corrected.
- If the components checked appear OK, road test the vehicle.
