Solution

1. Preparation

Gather tools and parts: socket set, torque wrench, brake cleaner, new brake pads (if needed), new rotors (if needed).
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts.
- Tools required: socket set.
Lift the caliper away and support it without stressing the brake line.
Inspect the brake pads for wear; if worn down to the indicator, replace them.
Remove the old pads and install new ones, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors

Check the rotor surface for warping or grooves.
If replacement is needed, remove the rotor by unscrewing the retaining screws or bolts.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor and secure it with the appropriate torque specifications (usually around 80-100 ft-lbs, but check manufacturer specs).

5. Reassemble and Test

Reattach the brake caliper and torque the bolts to manufacturer specifications.
Reinstall the wheel, hand-tightening the lug nuts before lowering the vehicle.
Once on the ground, torque the lug nuts to the specified value (usually around 80-100 ft-lbs).
Test the brake pedal for proper feel before taking the vehicle on a test drive.
