Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection: Remove the brake caliper by unbolting it from the bracket. Check the brake pads for uneven wear and measure their thickness.
Replacement: If pads are unevenly worn, replace them as follows:
1. Remove the old pads from the caliper bracket.
2. Install new brake pads (ensure they match OEM specifications).
3. Apply brake grease to the backing of the new pads to reduce noise.

4. Check and Service Brake Caliper

Clean the caliper slides and apply high-temperature grease.
Ensure the caliper moves freely; if it’s sticking, replace the caliper.
Ensure the caliper pistons are functioning properly; replace if necessary.

5. Inspect and Repair Suspension and Alignment

Check suspension components for wear, replace as needed.
Perform a wheel alignment, ensuring camber, caster, and toe are within specifications.

6. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Pump the brake pedal to seat the new pads.
Test drive the vehicle to ensure proper brake function and even operation.
