Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the front or rear wheels slightly without removing them.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Components

Brake Caliper:
- Remove caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord or similar to avoid stress on the brake line.
Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Inspect the backing plate and shims for damage.
Brake Rotor:
- If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

4. Inspect and Replace

Brake Pads:
- Replace with new brake pads if worn below the manufacturer's minimum thickness (usually around 3 mm).
Brake Rotor:
- If the rotor is scored or warped, replace it with a new one. If within specifications, resurface it if possible.
Caliper:
- Inspect the caliper for any leaks or damage. Replace if necessary.

5. Reassemble Components

Install new or resurfaced rotor onto the hub.
Attach new brake pads into the caliper bracket.
Reinstall the brake caliper over the new pads and secure it with the caliper bolts. Torque to the manufacturer’s specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands.
Tighten the lug nuts to the manufacturer’s specifications (typically 76-80 ft-lbs).
Pump the brake pedal several times to ensure proper caliper operation before driving.
