Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery.
Ensure the vehicle is on a level surface and use jack stands for safety if lifting the vehicle.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir and remove the cap.
Inspect the brake fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Replace the cap securely after refilling.

3. Repair Leaks

If any leaks are found in the brake lines, replace the damaged sections using a line wrench.
Tighten all fittings securely. If leaks are found at calipers, replace the caliper or seals as necessary.

4. Replace Master Cylinder (if necessary)

Remove the brake lines from the master cylinder using a line wrench.
Unbolt the master cylinder from the brake booster and carefully remove it.
Install the new master cylinder, ensuring to torque the bolts to manufacturer specifications.
Reconnect the brake lines and ensure there are no leaks.

5. Bleed Brake System

Fill the master cylinder reservoir with brake fluid.
Starting at the furthest brake caliper, bleed the brakes by having an assistant pump the brake pedal while you open and close the bleed valve on the caliper.
Repeat for each wheel, ensuring no air bubbles are present in the fluid.

6. Final Inspection

Recheck all fluid levels and inspect for any leaks.
Reconnect the negative battery terminal.
