Solution

1. Preparation

Ensure the vehicle is parked on a level surface, engage the parking brake.
Gather necessary tools and parts.

2. Inspect and Replace Brake Pads and Rotors

Remove the Wheel:
- Loosen lug nuts with a socket set.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel.
Inspect Brake Components:
- Check brake pads for thickness; replace if worn down beyond manufacturer specifications (usually less than 3mm).
- Inspect brake rotors for warping or scoring.
Replace Brake Pads:
- Remove caliper bolts using a socket.
- Slide the caliper off the rotor and support it without straining the brake line.
- Remove old brake pads and install new ones, ensuring they fit securely.
Replace Brake Rotors (if necessary):
- Remove the caliper bracket if required.
- Take off the rotor and install the new rotor.
- Reinstall caliper bracket and caliper.

3. Brake System Bleeding (if brake fluid was replaced)

Bleed Brake Lines:
- Start from the wheel furthest from the master cylinder.
- Use a brake bleeder kit or a helper to pump the brake pedal while you open the bleeder valve on each caliper.
- Close the valve before the pedal is released.
- Repeat until no air bubbles are present.

4. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).
