Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts with a socket wrench (do not completely remove).
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it using a bungee cord (do not hang by the brake line).
3. Remove old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of damage or sticking.
5. Install new brake pads into the caliper bracket, ensuring they are properly seated.

4. Inspect and Resurface or Replace Rotors

Sub-steps:
1. Check rotor surface for grooves or abnormalities.
2. If necessary, remove the rotor by unscrewing the retaining screws (if equipped).
3. Either resurface the rotor using a brake lathe or replace it with a new rotor.
4. Clean the new or resurfaced rotor with brake cleaner to remove any protective oil.

5. Reassemble Components

Sub-steps:
1. Reinstall the caliper over the new brake pads and onto the rotor.
2. Tighten caliper bolts to the manufacturer’s specified torque settings (typically around 25-30 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically 76 ft-lbs).

6. Final Checks

Pump the brake pedal several times to ensure proper pad seating.
Check brake fluid level and top off if necessary.
