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 and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid reservoir. If low, refill with the appropriate brake fluid type (DOT 3 or DOT 4).
Check for leaks; if leaks are found, proceed to address the source.

3. Identify and Repair Leaks

Tools Required: Wrench set, brake line repair kit (if needed)
Visually inspect all brake lines, hoses, calipers, and the master cylinder.
Tighten any loose fittings and replace damaged brake lines or seals as necessary.
If the master cylinder is leaking, replace it by removing the mounting bolts and disconnecting the brake lines.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing
Begin at the wheel furthest from the master cylinder (usually the right rear).
Attach the bleeder kit and open the bleeder valve while a helper applies pressure to the brake pedal.
Close the valve before the pedal reaches the floor and repeat until fluid runs clear of bubbles.
Move to the left rear, then right front, and finish with the left front wheel.

5. Test and Secure

Tools Required: Torque wrench
Ensure all components are properly reassembled and secured.
Test drive the vehicle to ensure proper brake function.
Check brake fluid level again and top off if necessary.
