Solution

1. Preparation

Gather 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. Check and Refill Brake Fluid

Tools Required: Brake fluid (recommended type: DOT 3 or DOT 4), funnel.
Open the hood and locate the master cylinder.
Inspect the brake fluid level; if low, add brake fluid until it reaches the maximum line.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit (if needed).
Visually check all brake lines, hoses, and connections for signs of leakage.
If leaks are found, replace the damaged brake lines or hoses as necessary, ensuring all connections are tight.

4. Replace Worn Components

Tools Required: Jack and jack stands, socket set, torque wrench.
Lift the vehicle and remove the wheel to access the brakes.
Inspect brake pads and rotors; replace if they are worn beyond specifications.
- Brake Pad Replacement:
  1. Remove caliper bolts and slide the caliper off.
  2. Replace the old pads with new ones, ensuring proper alignment.
  3. Reinstall the caliper and torque bolts to manufacturer specifications.
- Rotor Replacement (if necessary):
  1. Remove the caliper bracket.
  2. Slide off the old rotor and replace with a new rotor.
  3. Reinstall the caliper bracket and torque to specifications.

5. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container.
Attach the bleeder kit to the brake bleeder valve on each wheel.
Have an assistant pump the brake pedal and hold it down while you open the bleeder valve to release air and fluid.
Close the valve before the assistant releases the pedal. Repeat until no air bubbles are present.
Ensure the brake fluid reservoir remains filled during this process.
