Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves.
Tools Required: Socket set, brake fluid, brake bleeder kit, jack and jack stands.

2. Inspect and Repair Brake Lines

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect all brake lines and hoses for cracks, corrosion, or signs of leakage.
3. If a leak is found, replace the damaged section of the line or hose. Use a line cutter for metal lines and ensure proper fittings for hoses.
4. Tighten all connections to specifications.

3. Replace Brake Fluid

Sub-steps:
1. Open the master cylinder reservoir cap and remove any old brake fluid using a syringe or turkey baster.
2. Fill the reservoir with new, manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. Ensure that the reservoir is filled to the correct level.

4. Bleed the Brake System

Sub-steps:
1. Attach the brake bleeder kit to the brake caliper of the wheel farthest from the master cylinder (usually the right rear).
2. Have an assistant pump the brake pedal three times and hold it down.
3. Open the bleeder valve to allow fluid and air to escape, then close the valve before the assistant releases the brake pedal.
4. Repeat this process until no air bubbles are present in the fluid, then move to the next calipers in the order: right rear, left rear, right front, left front.
5. Check the fluid level in the master cylinder frequently and refill as necessary.

5. Test the Master Cylinder

Sub-steps:
1. With the brake system bled, pump the brake pedal several times to build pressure.
2. Inspect the master cylinder for any leaks around the seals.
3. If the pedal continues to go to the floor, the master cylinder may need replacement.
