Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Locate the Leak

Remove the engine cover (if applicable) to access the master cylinder.
Inspect the master cylinder for cracks or damage; replace if needed.
Check brake lines and hoses leading from the master cylinder to the wheels.

3. Repair or Replace Defective Components

For damaged brake lines:
- Use a line wrench to disconnect the damaged section.
- Cut and replace with new brake line tubing, flaring the ends as necessary.
- Reconnect using appropriate fittings and ensure tightness.
For a leaky master cylinder:
- Remove the retaining bolts using a socket set.
- Disconnect brake lines and electrical connectors.
- Install the new master cylinder, reconnect lines and connectors, and torque to manufacturer specifications.

4. Bleed the Brake System

Open the bleeder valve on each brake caliper, starting with the furthest from the master cylinder.
Use a brake bleeder tool or have an assistant pump the brake pedal to expel air until fluid runs clear.
Close the bleeder valve and repeat for each caliper.
Check and top off brake fluid in the reservoir.
