Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent accidental electrical contact.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket wrench.
Take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Remove Old Pads: Unbolt the caliper using a socket set and slide the caliper off the rotor. Remove the old pads from the caliper bracket.
Install New Pads: Apply brake grease to the backing of the new pads to prevent squeaking. Insert the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Measure rotor thickness with a micrometer. If below the minimum specification or showing damage, replace.
Remove Rotors: Unbolt the rotor from the hub (if applicable) and remove it.
Install New Rotors: Place the new rotor onto the hub and secure it with bolts to the manufacturer’s torque specifications.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Ensure all bolts are tightened to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
