Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if it has been recently driven.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the affected wheel slightly while the vehicle is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts with a socket wrench.
Carefully detach the caliper from the rotor, ensuring not to stretch the brake line.
Inspect the brake pads for thickness; replace if they are worn down to 3mm or less.
To install new pads, slide them into the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors

Check the rotor surface for grooves or scoring; replace if necessary.
If replacing, remove the rotor by unscrewing the retaining screws or bolts.
Clean the hub surface, then install the new rotor, ensuring it is properly aligned.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor; tighten the caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs, but check specific torque specs for your model).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the brake pads.
Check the brake fluid level and add fluid if necessary.
