Solution

1. Preparation

Tools Required:
- Safety goggles
- Gloves
- Brake cleaner
- Wrench set
- Torque wrench
- Brake fluid
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Identify the Leak Source

Begin by cleaning the brake components with brake cleaner to remove dirt and debris.
Carefully inspect the brake fluid reservoir, lines, calipers, and master cylinder for any signs of leaks.

3. Replace Damaged Components

If the brake fluid reservoir is damaged:
- Disconnect the electrical connector (if equipped) and remove the reservoir cap.
- Remove the reservoir from the mounting points and install a new reservoir, tightening to the manufacturer's torque specifications.
If brake lines are damaged:
- Use the wrench set to disconnect the leaking brake line from its fittings.
- Replace the damaged line with a new one, ensuring proper routing and secure connections.
If calipers are leaking:
- Remove the wheel and inspect the caliper.
- If leaking, unbolt the caliper from the bracket and replace it with a new caliper, ensuring to torque the bolts to specification.
If the master cylinder is leaking:
- Disconnect the brake lines and electrical connectors.
- Remove the master cylinder from the brake booster and replace it with a new one, ensuring proper alignment and torque.

4. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the specified brake fluid type as per manufacturer's guidelines.
Bleed the brake system to remove any air pockets by starting from the farthest wheel from the master cylinder and working toward the closest.

5. Test the Brake System

Once repairs are done, pump the brake pedal to ensure a firm feel.
Check for any leaks after the system has been bled and the vehicle is under pressure.
