Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and use wheel chocks.
Disconnect the battery to prevent any electrical issues while working on the braking system.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean rags
Locate the brake fluid reservoir and remove the cap.
Inspect the fluid level; if low, refill with the manufacturer-recommended brake fluid.
Clean the reservoir cap and surrounding area before sealing it back.

3. Inspect and Repair Brake Components

Tools Required: Wrench set, socket set, brake line wrench
Check the master cylinder: If leaking, replace the master cylinder.
- Remove the brake lines using a brake line wrench.
- Unbolt the master cylinder from the brake booster and replace it with a new one.
Inspect brake lines: Replace any damaged or corroded brake lines or hoses.
- Use a wrench to disconnect the affected lines, install new ones, and ensure they are securely fastened.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old fluid
Start with the wheel furthest from the master cylinder (usually the passenger rear).
Attach the clear tubing to the bleeder valve, and have an assistant press the brake pedal while you open the valve.
Close the valve before the pedal reaches the floor and repeat until no air bubbles are visible in the fluid. Proceed to the next wheel in the correct order (passenger front, driver rear, driver front).
Ensure the brake fluid reservoir remains full throughout the process.

5. Test Brake System

Reconnect the battery and start the vehicle.
Press the brake pedal to ensure it feels firm and does not go to the floor.
Conduct a test drive at low speeds to confirm proper brake function and listen for any unusual sounds.
