Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen wheel nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove caliper bolts with a socket set.
Carefully slide the caliper off the rotor without stretching the brake line.
Remove old brake pads; check for thickness (replace if less than 3mm).
Install new brake pads, ensuring they are correctly oriented.

4. Check and Resurface or Replace Brake Rotors

Measure the rotor thickness with a micrometer (should be within manufacturer specifications).
If warped or scored, resurface the rotors or replace them if they are below minimum thickness specifications.
Clean the rotor surface with brake cleaner to remove any debris.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer’s specified torque.
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Carefully lower the vehicle off the jack stands.
Tighten the lug nuts to the specified torque in a crisscross pattern.
Pump the brake pedal a few times to ensure proper pad seating.
