Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel lug nuts with a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Check brake pads for wear; they should have at least 1/4 inch of material remaining.
Replacement:
- If worn down, remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the bracket, ensuring they are seated correctly.

4. Check and Resurface/Replace Rotors

Inspection: Check rotors for grooves or excessive wear.
Resurfacing: If within service limits, have rotors resurfaced at a machine shop.
Replacement: If damaged, remove the rotor by unscrewing the retaining screws and slide it off the hub. Install the new rotor by reversing this process.

5. Reassemble Components

Reattach the caliper over the new pads and torque caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

6. Final Inspection

Check brake fluid level and top off if necessary.
Test the brake pedal for firmness before driving.
