Solution

1. Preparation

Tools Required: Socket set, brake line wrench, jack and jack stands, brake fluid, cleaning rags, pressure tester.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repair.

2. Locate the Leak

Inspect the brake lines, calipers, master cylinder, and hoses to identify the source of the leak.
Clean any dirt or debris around the suspected leak area for better visibility.

3. Replace Damaged Components

If the leak is from a brake line:
- Use a brake line wrench to disconnect the affected line from the fitting.
- Measure and cut a new brake line to the appropriate length.
- Attach the new line using the proper fittings and torque specifications.
If the leak is from a caliper:
- Remove the caliper bolts and disconnect the brake line from the caliper.
- Replace the caliper with a new unit if necessary.
- Reattach the brake line and torque to specifications.
If the leak is from the master cylinder:
- Remove the master cylinder by unbolting it from the brake booster.
- Replace the master cylinder with a new one and bolt it back into place.

4. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the recommended brake fluid type (DOT 3, DOT 4, etc. as specified).
Bleed the brake system using a pressure bleeder or manually, starting from the furthest wheel from the master cylinder to the nearest.
Ensure there are no air bubbles in the system.

5. Final Inspection

Reconnect the battery.
Check all connections for leaks after the system has been bled.
Test the brake pedal feel by pressing down and ensuring it feels firm.
