Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Elevate the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Compare new pads to old ones to ensure proper fit.
Install new brake pads in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Remove the caliper bracket by unscrewing the bolts.
Inspect the rotors for scoring; if necessary, use a brake lathe to resurface or replace them if they are below the minimum thickness specification.
Clean the rotor surface with brake cleaner to remove any debris or oil.

5. Reassemble Components

Reinstall the caliper bracket and torque the bolts to the manufacturer’s specifications (usually around 75-100 ft-lbs).
Reattach the caliper over the new pads and torque caliper bolts to specifications (generally 25-30 ft-lbs).
Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to specifications (typically 100-120 ft-lbs).

6. Final Checks

Check brake fluid level in the master cylinder and top off if necessary.
Start the vehicle and pump the brakes to ensure proper seating of the pads.
