Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Brake Fluid

Check Brake Fluid Level
- Open the master cylinder reservoir cap.
- If the fluid is low, refill it with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Flush Old Brake Fluid
- Attach a brake bleeder kit to the brake bleeder valve on each wheel.
- Open the valve and allow old fluid to drain until new fluid flows out.
- Repeat for all wheels, ensuring no air enters the system.

3. Inspect Brake Components

Brake Line Inspection
- Visually inspect all brake lines for any signs of wear or leaks.
- Replace any damaged lines with new OEM parts.
Brake Pad and Rotor Inspection
- Remove the wheel and inspect the brake pads and rotors for wear.
- Replace pads if they are worn below the manufacturer's specification (typically 3mm).
- Resurface or replace rotors if they are damaged or worn.

4. Bleed Brake Lines

Bleeding Process
- Starting from the wheel farthest from the master cylinder (usually the rear passenger side), open the bleeder valve.
- Have an assistant pump the brake pedal several times and hold it down while you open the valve to allow air and fluid to escape.
- Close the bleeder valve before releasing the brake pedal. Repeat until there are no air bubbles in the fluid.
- Move to the next wheel and repeat until all wheels are bled.

5. Test Brake Booster

Check Brake Booster Functionality
- With the engine off, pump the brake pedal several times to deplete vacuum.
- Hold the brake pedal down and start the engine; the pedal should drop slightly if the booster is functioning correctly. If it does not, the brake booster may need replacement.
