Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect Brake Fluid

Tools Required: None
Check the brake fluid reservoir and refill with DOT 3 or DOT 4 brake fluid if low.
Inspect for leaks around the reservoir, lines, and master cylinder.

3. Inspect and Replace Damaged Components

Tools Required: Socket set, wrenches
If leaks are found in brake lines or hoses, replace the damaged sections.
- Loosen the fittings using the appropriate size wrench.
- Remove and replace the damaged line or hose.
- Tighten new components to manufacturer specifications (typically around 20-25 ft-lbs for brake lines).

4. Bleed Brake System

Tools Required: Brake bleeder kit, clear tubing, container for fluid
Begin with the brake furthest from the master cylinder (usually rear passenger side):
- Attach the clear tubing to the bleeder valve and place the other end in a container.
- Have an assistant pump the brake pedal several times, then hold it down.
- Open the bleeder valve to allow fluid and air to escape until clear fluid flows out.
- Close the bleeder valve and repeat for each wheel in the following order: rear passenger, rear driver, front passenger, front driver.
Check the brake fluid level after bleeding and top off if necessary.

5. Test Brake System

Tools Required: None
Start the engine and press the brake pedal several times to ensure it feels firm.
Conduct a test drive to verify braking performance.
