Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Locate the Leak

Tools Required: Flashlight
Visually inspect the brake fluid reservoir, master cylinder, and all brake lines for signs of leakage.
Use a flashlight to check hard-to-see areas around the brake components.

3. Replace Damaged Components

Tools Required: Wrench set, socket set, brake line tool
If leaks are found in brake lines, replace the affected section:
1. Use a wrench to disconnect the damaged brake line.
2. Remove any mounting clips or brackets.
3. Install the new brake line and secure it with clips.
4. Tighten all connections to the manufacturer’s torque specifications.

4. Replace Master Cylinder (if necessary)

Tools Required: Wrench set, brake fluid
If the master cylinder is leaking:
1. Disconnect brake lines from the master cylinder.
2. Remove the mounting bolts and take out the master cylinder.
3. Install the new master cylinder and torque bolts to specifications.
4. Reconnect brake lines and ensure tight seals.

5. Bleed the Brakes

Tools Required: Brake bleeder kit
After replacing components, bleed the brake system:
1. Start with the wheel furthest from the master cylinder.
2. Attach the bleeder kit and open the valve while having an assistant pump the brake pedal.
3. Close the valve before releasing the pedal to avoid sucking air back in.
4. Repeat for all wheels until the pedal feels firm and fluid runs clear.
