Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).

3. Inspect and Repair Brake Lines

Visually inspect brake lines for corrosion or leaks.
If leaks are found, replace the damaged section of the brake line using a brake line repair kit.
Ensure all connections are tight and secure.

4. Replace Brake Master Cylinder (if necessary)

Disconnect the battery to prevent electrical shorts.
Remove the brake fluid reservoir cap and siphon out old fluid.
Disconnect brake lines from the master cylinder using a flare nut wrench.
Unbolt the master cylinder from the brake booster using a socket set.
Install the new master cylinder by reversing the removal steps.
Refill the brake fluid reservoir with fresh brake fluid.

5. Bleed the Brake System

Start with the brake furthest from the master cylinder (usually the right rear).
Connect a clear hose to the bleeder valve and submerge the other end in a container of brake fluid.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat until no air bubbles appear in the fluid.
Move to the next brake in the order: left rear, right front, and finally left front.
