Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface, and use wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level.
If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the cap securely.

3. Inspect and Replace Brake Pads and Rotors (if necessary)

Remove Wheel:
- Loosen lug nuts before lifting the vehicle.
- Use a jack to raise the vehicle and secure with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Pads:
- Check the thickness of the brake pads. Replace if below specifications (usually less than 3mm).
- If pads are worn, remove the caliper bolts with a socket set.
- Lift the caliper off the rotor and support it with a bungee cord or wire.
Inspect Rotors:
- Check the rotor surface for scoring or excessive wear.
- If damaged, remove the rotor by unscrewing the retaining screws and sliding it off.
Replace Components:
- Install new brake pads and/or rotors as needed.
- Ensure all components are properly aligned.

4. Bleed the Brake System

Prepare to Bleed:
- Reconnect the battery.
- Fill the brake fluid reservoir to the proper level.
Bleed the Brakes:
- Start at the wheel farthest from the master cylinder (usually the rear passenger side).
- Attach a clear hose to the bleeder valve and place the other end in a container.
- Open the valve while a helper presses the brake pedal down.
- Close the valve before the pedal is released. Repeat until no air bubbles appear.
- Move to the next wheel and repeat the process (rear driver, front passenger, front driver).

5. Final Assembly and Testing

Reinstall the wheels and torque lug nuts to manufacturer specifications (typically 76-80 ft-lbs).
Lower the vehicle and perform a test drive to ensure brakes are functioning correctly.
