Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely supported with jack stands.

Tools Required:

Socket set
Brake line wrench
Brake fluid
OBD-II scanner
Vacuum bleeder or brake bleeder kit
Torque wrench

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir.
Remove the cap and inspect the fluid level.
If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Inspect and Repair Leaks

Examine brake lines, calipers, and wheel cylinders for leaks.
If any leaks are found, replace the damaged components (e.g., brake hoses, calipers).

Parts Required:

Replacement brake fluid
Brake lines (if damaged)
Brake calipers (if leaking)

4. Bleed the Brake System

Attach a vacuum bleeder to the brake bleeder valve on the caliper.
Open the bleeder valve and allow fluid to flow until there are no air bubbles in the fluid.
Close the bleeder valve and repeat for all brake calipers, starting from the furthest from the master cylinder (usually right rear, left rear, right front, left front).

5. Final Assembly

Ensure all bleeder valves are securely closed.
Recheck the brake fluid level in the master cylinder and top off if necessary.
Replace the master cylinder reservoir cap.
