Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Inspect and Address Leaks

Tools Required: Wrench set, brake fluid.
Check for any leaks in the brake lines, calipers, or master cylinder.
If a leak is found, replace the damaged component (line, caliper, or master cylinder) as necessary.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old brake fluid.
Begin at the wheel farthest from the master cylinder (usually the right rear).
Attach the clear tubing to the bleeder valve and submerge the other end in the container.
Open the bleeder valve and have an assistant press the brake pedal.
Close the valve while the pedal is still pressed and then release the pedal.
Repeat the process until no air bubbles escape and fluid runs clear.
Move to the next wheel (left rear, right front, left front) and repeat.

4. Replace Brake Fluid

Tools Required: Brake fluid of the specified type (usually DOT 3 or DOT 4).
After bleeding, refill the master cylinder reservoir with fresh brake fluid.
Ensure the fluid level is between the minimum and maximum marks.

5. Final Reassembly

Reinstall any components removed during the repair.
Test the brake pedal for firmness before taking the vehicle out of the garage.
