Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Identify and Isolate the Leak

Step 1: Clean the area around the brake fluid reservoir and master cylinder using brake cleaner to remove any fluid residue for better visibility.
Step 2: Fill the brake fluid reservoir to the recommended level with the appropriate brake fluid type (DOT 4 or as specified by the manufacturer).
Step 3: Start the engine and press the brake pedal several times to pressurize the system; observe for any visible leaks.

3. Repair the Leak

Step 1: If the leak is from the brake lines:
- Use a pipe cutter to remove the damaged section of the brake line.
- Install a new brake line using appropriate fittings and flare tools.
- Bleed the brake system to remove air from the lines.
Step 2: If the leak is from the calipers:
- Remove the wheel and inspect caliper bolts; replace seals if necessary.
- If calipers are damaged, they should be replaced with new or remanufactured units.
Step 3: If the master cylinder is leaking:
- Disconnect brake lines from the master cylinder.
- Unbolt the master cylinder from its mounting points.
- Install the new master cylinder and reconnect the brake lines.
Step 4: Refill the brake fluid reservoir with the appropriate fluid and bleed the brake system.

4. Final Assembly

Reinstall any components removed during the inspection and repair process.
Ensure all connections are secure and there are no leaks.
