Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a ratchet and socket.
Slide the caliper off the brake rotor and support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad thickness; replace if worn down to the minimum thickness.
Install new brake pads, ensuring they are correctly positioned in the caliper bracket.

4. Inspect and Resurface or Replace Rotors

Use a runout gauge to check rotors for warping.
If rotors are within specifications, resurface them using a brake lathe.
If rotors are too warped or worn, replace them with new ones.
Ensure the surface is clean before reinstalling the caliper.

5. Reassemble and Test

Reinstall the caliper and secure it with the caliper bolts, tightening to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and lug nuts, tightening in a star pattern to ensure even pressure.
Lower the vehicle and reconnect the battery.
