Solution

1. Preparation

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

2. Wheel Removal

Tools Required: Socket set, jack, jack stands.
Loosen lug nuts slightly before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Brake Pad and Rotor Inspection

Tools Required: Wrench, torque wrench.
Inspect the brake pads for thickness; replace if less than 3mm.
Check the rotors for scoring or excessive wear; replace if damaged.
Use a torque wrench to measure rotor thickness; replace if below spec.

4. Brake Pad Replacement

Remove the caliper bolts using a wrench.
Carefully slide the caliper off the rotor, supporting it to avoid damaging the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are correctly positioned.

5. Rotor Replacement (if necessary)

Remove the old rotor by removing any retaining screws.
Clean the hub surface with brake cleaner.
Install the new rotor, securing it with any retaining screws if present.

6. Reassemble

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to manufacturer specifications using a torque wrench.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.
