Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues while working on the brake system.

2. Inspect and Replace Brake Fluid Reservoir

Tools Required: Socket set, torque wrench.
Remove the cap from the brake fluid reservoir.
Inspect the reservoir for cracks or damage; if damaged, replace with a new reservoir.
Install the new reservoir and tighten bolts to manufacturer specifications (typically around 10-12 Nm).
Refill with the recommended brake fluid type (usually DOT 4).

3. Inspect and Replace Damaged Brake Lines

Tools Required: Brake line wrench, cutting tool, flaring tool.
Identify the location of the leak in the brake lines.
If a line is damaged, use the cutting tool to remove the compromised section.
Use the flaring tool to create a new flare on the end of the new brake line.
Connect the new line securely and bleed the brake system to remove air.

4. Replace Brake Calipers or Wheel Cylinders (if necessary)

Tools Required: Jack, jack stands, socket set.
Lift the vehicle and remove the wheel to access the brake caliper or wheel cylinder.
Inspect for leaks; if found, remove the caliper or cylinder.
Install a new caliper or cylinder, ensuring all seals are correctly seated.
Reassemble the wheel and lower the vehicle.

5. Inspect and Replace Master Cylinder (if necessary)

Tools Required: Socket set, brake line wrench.
Locate the master cylinder and check for leaks around the seals.
If leaking, disconnect the brake lines (note fluid loss) and unbolt the master cylinder.
Install a new master cylinder and reconnect brake lines securely.
Bleed the braking system thoroughly.
