Verify the front brake clearance. Measure the clearances individually and add the clearances together for total clearance before removing the
caliper. If the caliper (total clearance) to the steering knuckle stops is under 0.20 mm (0.008 in), correct this by filing metal off at the steering
knuckle stops in order to obtain a total clearance of 0.26-0.60 mm (0.010-0.024 in). DO NOT FILE METAL OFF OF THE CALIPER.

Inspect all of the front brake components and replace only if necessary.
-
Verify the rear brake clearance/adjustment, including the park brake.
