Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure it is turned off.
Wear safety glasses and gloves before beginning the repair.

2. Inspect and Replace Leaking Components

Tools Required: Wrench set, brake line wrench, jack, jack stands
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the brake components.
3. Inspect all brake lines and hoses for signs of leakage or damage.
4. If leaks are found, replace the damaged brake line or hose.
5. Tighten all connections to the manufacturer’s torque specifications.

3. Refill Brake Fluid

Tools Required: Funnel, clean container for fluid
1. Locate the brake fluid reservoir under the hood.
2. Clean the reservoir cap and area to prevent contamination.
3. Remove the cap and check the fluid level; refill with the appropriate brake fluid (typically DOT 3 or DOT 4).
4. Replace the cap securely after refilling.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, brake fluid
1. Start at the wheel farthest from the master cylinder and work towards the nearest.
2. Attach the bleeder kit or tubing to the bleeder valve on the brake caliper.
3. Have an assistant press the brake pedal while you open the bleeder valve to release air.
4. Close the valve before the pedal is released to prevent air from entering.
5. Repeat until no air bubbles are visible in the fluid.
6. Check fluid level in the reservoir and refill as necessary.
