Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, caliper tool, brake cleaner.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before starting any work. Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts of the wheel using a lug wrench.
Lift the vehicle with a jack and place jack stands securely under the vehicle.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Visual Inspection: Check the brake pads for uneven wear. If one side is significantly thinner, it likely needs replacement.
Remove Caliper:
- Locate the caliper mounting bolts and remove them using a socket.
- Carefully lift the caliper off the brake rotor and support it with a bungee cord or a wire (do not let it hang by the brake line).
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
- Note the orientation for reassembly.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent noise.
- Slide the new pads into the caliper bracket.
Reinstall Caliper:
- Press the caliper over the new pads and align it with the rotor.
- Reinstall and tighten the caliper mounting bolts to the manufacturer’s torque specifications.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor for wear, warping, or scoring.
If replacement is necessary, remove the rotor by taking off any retaining screws and sliding it off the hub.
Install the new rotor and secure it as per manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal several times to seat the new pads.
Check brake fluid level and top off if necessary.
