Solution

1. Preparation

Tools Required: Socket set, wrenches, brake fluid, rags, brake cleaner, multimeter (if needed)
Safety Warnings: Ensure the vehicle is on a level surface and securely lifted before working underneath. Wear gloves and safety goggles.

2. Locate the Leak

Inspect all components of the brake system, including brake lines, calipers, master cylinder, and brake fluid reservoir.
Clean any areas with brake cleaner to better identify the source of the leak.

3. Replace Damaged Components

For Brake Lines:
1. Use a wrench to disconnect the faulty brake line from the caliper and master cylinder.
2. Remove the old brake line and install a new one, ensuring it is routed correctly.
3. Torque the fittings to the manufacturer’s specifications.
For Brake Calipers:
1. Remove the wheel and secure the vehicle.
2. Disconnect the brake line from the caliper using a wrench.
3. Unbolt the caliper from the bracket and remove it.
4. Install the new caliper, reconnect the brake line, and torque to specification.
For Master Cylinder:
1. Disconnect the battery to prevent any electrical issues.
2. Remove the brake fluid reservoir cap and drain old fluid.
3. Unbolt the master cylinder from the brake booster.
4. Install a new master cylinder, ensuring proper alignment, and torque the bolts.
For Brake Fluid Reservoir:
1. Disconnect any electrical connectors linked to the reservoir.
2. Remove the reservoir from its mounting position.
3. Install a new reservoir and reconnect any connectors.

4. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the manufacturer-recommended brake fluid.
Bleed the brake system starting from the wheel farthest from the master cylinder and proceeding to the closest.
Ensure each brake line is bled until clear fluid with no bubbles flows out.
