Brake System Inspection Checklist

Share

Crucial Component

To ensure that the brakes are in proper working order, the brake system should be inspected periodically. This checklist is a handy reminder of the steps you should follow when inspecting the brake system.

Check Brake Fluid

Steps to Take

  • Look at minimum and maximum fill lines on master cylinder
  • Check position of master cylinder float
  • Assess the condition of the brake fluid

Considerations

For brake fluid service, follow the manufacturer’s recommendations. Brake fluid service can promote brake pad life and longer caliper life. When contaminants build up in brake fluid, they migrate to the lowest part of the brake system, the brake caliper. The contaminants will settle in the bottom of the brake caliper behind the caliper piston and can cause the caliper piston to bind/seize; this can shorten brake pad life and require caliper replacement to repair.

Check Brake Pads

Steps to Take

  • Raise vehicle
  • Remove brake caliper
  • Remove brake pads from anchor bracket
  • Examine brake pads

Considerations

  • Inner and outer pads should wear at the same rate
  • Uneven wear can indicate another problem
  • Excessive wear on outside pad while inside pad looks new can indicated seized slide pins
  • Inner pad wear with a like-new outer pad can point to the caliper piston dragging and not releasing when the driver takes foot off the brake pedal. Learn more about checking brake pads.

Inspect Brake Caliper

Steps to Take

  • Examine boots for damage like rips, tears or cracks
  • Ensure caliper slide pin is moving freely

Considerations

If there is uneven pad wear and there are no issues with external caliper hardware (seized slide pins, brake pads binding in the caliper bracket), the cause could be a seized caliper piston or a restriction in the rubber brake hose. If the piston is hard to move or won’t move when pushing the brake caliper piston back into the brake caliper housing, crack the brake caliper fluid bleed screw loose. If the brake caliper piston now moves, this indicates a restriction in the rubber brake hose requiring brake hose replacement. If the brake caliper piston still binds or will not move with the brake caliper fluid bleed screw loosened, this indicates a concern internal to the brake caliper requiring brake caliper replacement. If brake caliper replacement is required, it is also necessary to perform a brake fluid air bleed procedure at that caliper. Learn more about checking the caliper.

Examine Brake Rotor

Steps to Take

  • Get caliper bracket out of the way
  • Look at rotor surfaces for rust

Considerations

Replace rotor if surfaces are excessively worn and/or rusted. Learn more about checking the rotor.

Examine Caliper Hardware

Steps to Take

  • Remove abutment clips
  • Examine area where abutment clips sat
  • Clean any signs of rust

Considerations

If the rust isn’t removed, it can cause the brake pad to bind in the brake and could contribute to uneven wear.
