Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Wear safety goggles and gloves for protection.

2. Inspect and Replace Brake Fluid

Step 2.1: Open the hood and locate the brake master cylinder reservoir.
Step 2.2: If the fluid is low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Step 2.3: If fluid is contaminated, proceed to replace it.

3. Inspect Brake Lines and Hoses

Step 3.1: Visually inspect all brake lines and hoses from the master cylinder to the wheels for any signs of wear or leaks.
Step 3.2: If any leaks are detected, replace the affected line or hose.
Step 3.3: Ensure all connections are secure and properly tightened.

4. Bleed the Brake System

Step 4.1: Use a brake bleeder kit or have an assistant help to pump the brake pedal.
Step 4.2: Starting from the wheel farthest from the master cylinder, attach the bleeder kit to the brake caliper and open the bleeder valve.
Step 4.3: Have the assistant pump the brake pedal and hold it down while you close the bleeder valve, then repeat until no air bubbles are visible in the fluid.
Step 4.4: Repeat this process for each wheel in the order: rear right, rear left, front right, front left.

5. Test the Master Cylinder

Step 5.1: With the vehicle off, pump the brake pedal several times and hold it down.
Step 5.2: If the pedal slowly sinks, the master cylinder may be faulty and should be replaced.

6. Replace the Master Cylinder (if necessary)

Step 6.1: Disconnect the brake lines from the master cylinder using a line wrench, being careful to catch any fluid.
Step 6.2: Unbolt the master cylinder from the brake booster and remove it.
Step 6.3: Install the new master cylinder, ensuring proper alignment, and torque the bolts to manufacturer specifications.
Step 6.4: Reconnect the brake lines and bleed the brake system again to remove any trapped air.
