Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts of the wheel on the affected side.
Lift the vehicle with a jack and securely place jack stands beneath the frame.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the brake rotor and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Compare new pads with old ones to ensure proper fit. Install new pads in reverse order of removal.

4. Inspect and Resurface or Replace Brake Rotors

Check the rotor surface for any signs of warping or scoring.
If warped, remove the rotor by unscrewing the rotor retaining screws (if equipped) and sliding it off the hub.
Have the rotors resurfaced at a machine shop or replace them if severely damaged.
Install the rotor back onto the hub.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to manufacturer torque specifications (usually around 100-120 Nm).

6. Final Checks

Lower the vehicle and check brake fluid levels, adding if necessary.
Pump the brake pedal to ensure proper caliper function and pad alignment.
