Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear protective gloves and goggles.

2. Remove the Brake Fluid Reservoir Cap

Carefully remove the cap from the brake fluid reservoir.
Use a clean rag to wipe any dirt around the reservoir opening to prevent contamination.

3. Inspect and Replace Brake Lines

Tools Required: Wrenches, brake line wrench, flare nut wrench.
Locate any damaged brake lines.
Use a wrench to disconnect the damaged line from the fitting.
Cut a new brake line to the appropriate length, ensuring it matches the old line.
Install the new line using the flare nut wrench, ensuring it is tight but not over-torqued.

4. Replace Leaking Calipers or Wheel Cylinders

Tools Required: Socket set, brake cleaner, torque wrench.
Remove the wheel to access the brake components.
Disconnect the brake line from the caliper or cylinder using a wrench.
Unbolt the caliper or cylinder and remove it from the bracket.
Install the new caliper or cylinder and secure it with bolts.
Reconnect the brake line and ensure it is tight.

5. Refill and Bleed the Brake System

Fill the brake fluid reservoir with the appropriate fluid type (DOT 3 or DOT 4).
Begin bleeding the brakes, starting from the furthest wheel from the master cylinder.
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve to remove air.
Repeat for all wheels until the fluid is clear and free of bubbles.

6. Reassemble Components

Replace the brake fluid reservoir cap securely.
Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the manufacturer's specified torque.
