Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Wheel Removal

Tools Required: Socket set, jack, jack stands.
Loosen the lug nuts slightly while the wheel is still on the ground.
Use the jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Pad and Rotor Inspection

Tools Required: Torque wrench, brake cleaner.
Inspect the brake pads for thickness; replace if worn below 3mm.
Check the brake rotors for scoring or warping; replace if necessary.
- If rotors are within service limits, clean them with brake cleaner.

4. Brake Pad Replacement (if needed)

Remove the caliper bolts using the socket set.
Lift the caliper off the rotor and support it (do not hang by the brake line).
Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads and install them in the caliper bracket.
Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually 25-30 ft-lbs).

5. Rotor Replacement (if needed)

If replacing the rotor, remove the caliper bracket using the socket set.
Remove the old rotor from the hub; clean the hub surface.
Install the new rotor and reattach the caliper bracket, torquing to manufacturer specifications.

6. Reassembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 76-80 ft-lbs).
Recheck brake fluid level in the master cylinder; top off if necessary.
