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

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts using a socket set and carefully lift the caliper off the rotor.
Sub-step 2: Remove the old brake pads from the caliper bracket.
Sub-step 3: Compare new brake pads with old ones for size and fit.
Sub-step 4: Install new brake pads into the caliper bracket, ensuring they are properly seated.

4. Inspect and Resurface/Replace Rotors

Sub-step 1: Check the rotor surface for any scoring or warping. If damaged, replace rotors or have them resurfaced.
Sub-step 2: Clean the rotor surface with brake cleaner to remove dust and debris before reassembly.

5. Reassemble Braking System

Sub-step 1: Reinstall the caliper over the new brake pads.
Sub-step 2: Torque the caliper bolts to the manufacturer’s specifications (typically 20-30 ft-lbs).
Sub-step 3: Reinstall the wheel and hand-tighten the lug nuts.
Sub-step 4: Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically 80-100 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.
