Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the brake caliper by loosening the caliper bolts.
- Take off the caliper and hang it using a wire to avoid straining the brake line.
- Check both inner and outer pads for wear.
Replace Brake Pads (if necessary):
- If uneven wear is confirmed, replace both inner and outer pads on the affected axle.
- Use a brake pad spreader tool to compress the caliper piston.
- Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Inspect the rotors for grooves or warping.
- If damaged, replace the rotors by removing the caliper bracket and rotor.

5. Reassemble Brake Components

Reattach the brake caliper and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 20-25 ft-lbs, verify with service manual).
Reinstall the wheel and lug nuts, tightening in a crisscross pattern to the specified torque (usually 100-120 ft-lbs).

6. Test Brake Function

Lower the vehicle and perform a brake test to ensure proper operation.
Check for any leaks around the brake system.
