Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Inspect and Refill Brake Fluid

Remove the cap from the brake fluid reservoir.
Check the fluid level; if low, add DOT 3 or DOT 4 brake fluid until it reaches the recommended level.
Replace the cap securely.

3. Fix Leaks

If leaks are found in the brake lines:
- 3.1. Replace Damaged Brake Lines:
  - Use a wrench to disconnect the damaged line from the master cylinder and caliper.
  - Replace with new brake line of the same specification.
  - Tighten connections to manufacturer’s torque specifications (usually around 10-15 ft-lbs).
If calipers or wheel cylinders are leaking:
- 3.2. Replace Calipers or Wheel Cylinders:
  - Remove the wheel and tire.
  - Disconnect brake line from caliper.
  - Remove caliper bolts and replace the caliper with a new one.
  - Reconnect the brake line and bleed the brakes after installation.

4. Bleed the Brake System

4.1. Bleeding Procedure:
- Start with the wheel farthest from the master cylinder (usually the right rear).
- Attach a clear hose to the bleeder valve and submerge it in a container with brake fluid.
- Have an assistant press the brake pedal slowly and hold it down.
- Open the bleeder valve to release air and fluid, then close it before releasing the pedal.
- Repeat until no air bubbles are present, moving to each wheel in order: right rear, left rear, right front, left front.

5. Inspect and Replace Brake Pads if Necessary

If brake pads are worn:
- Remove the caliper.
- Replace the brake pads with new ones ensuring proper alignment.
- Reinstall the caliper and secure it according to torque specifications.
