Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the brake rotor without disconnecting the brake line.
- Inspect the brake pads for uneven wear; replace if necessary.
Replacement:
- If replacing pads, compress the caliper piston using a C-clamp or brake tool.
- Install new brake pads, ensuring they are seated properly in the caliper bracket.
- Reinstall the caliper and torque the bolts to manufacturer specifications (typically 20-30 ft-lbs).

4. Check and Replace Rotor (if necessary)

If rotors are warped or excessively worn, they should be replaced.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and secure it as per manufacturer instructions.

5. Reassemble Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
Repeat for the other side if necessary.

6. Brake Fluid Check

Check brake fluid level in the master cylinder; refill if needed with the correct type (usually DOT 3 or 4).
Bleed brake lines if air was introduced during caliper removal.
