Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear protective gloves and eyewear.

Tools Required:

Jack and jack stands
Wrench set
Brake fluid
Clean rags
Brake line repair kit (if applicable)
Torque wrench

2. Locate the Leak

Inspect the brake fluid reservoir and lines:
- Remove the reservoir cap and check for fluid.
- Follow the brake lines from the master cylinder to the wheels, looking for wet spots or damage.
Examine the brake calipers:
- Inspect the caliper seals and bleeder valves for fluid leaks.

3. Repair the Leak

If the leak is from a brake line:
- Cut out the damaged section of the line using a pipe cutter.
- Use a brake line repair kit to replace with a new section.
- Ensure all connections are tight and no leaks are present afterward.
If the leak is from the caliper or master cylinder:
- Remove the affected component.
- Replace seals or the entire caliper/master cylinder if necessary.
- Reinstall the component, ensuring all bolts are torqued to manufacturer specifications.

4. Refill and Bleed the Brakes

Refill the brake fluid reservoir with the appropriate type of brake fluid (e.g., DOT 3 or DOT 4).
Bleed the brake system:
- Start from the wheel farthest from the master cylinder and work your way to the closest.
- Use the brake bleeder tool to remove any air from the system until clean fluid runs out.
