Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Check and Replace Brake Fluid

Sub-steps:
- Remove the master cylinder cap and inspect the brake fluid. If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
- If fluid is contaminated (dark or has debris), proceed to flush the brake system.

3. Inspect and Repair Brake Lines

Sub-steps:
- Visually inspect all brake lines for corrosion, cracks, or leaks.
- If leaks are found, replace the damaged section of the brake line using a flare wrench.
- Refill the brake fluid after repair and bleed the brake system to remove air.

4. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake calipers and pads.
- Inspect brake pads for wear; replace if thickness is less than 3mm.
- Check brake rotors for warping or grooves; replace if necessary.

5. Bleed the Brake System

Sub-steps:
- Start at the wheel farthest from the master cylinder (usually the right rear).
- Attach a clear hose to the bleed screw and submerge the other end in a container with brake fluid.
- Have an assistant pump the brake pedal several times, then hold it down while you open the bleed screw to release air and fluid.
- Close the bleed screw before the pedal is released. Repeat until no air bubbles appear.
- Move to the next wheels in the order: right rear, left rear, right front, left front.
