Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors

Use a dial indicator to check for warping. Replace if necessary.
If the rotors are within specifications, clean them with brake cleaner.

Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it without disconnecting the brake line.
Remove old brake pads and compare them to new ones for size.
Install new brake pads, ensuring they are aligned correctly.

4. Reinstall Brake Components

Reattach the caliper over the new brake pads.
Torque caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Lower the vehicle carefully and remove jack stands.
Torque lug nuts to the manufacturer's specifications (usually 75-90 ft-lbs).
