Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir.
Remove the cap and check the fluid level. If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Reinstall the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, and a container for old fluid.
Connect the tubing to the brake bleeder valve on the farthest brake caliper from the master cylinder.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow fluid and air to escape, then close it before the pedal is released.
Repeat this process until no more air bubbles are visible in the fluid.
Move to the next closest brake caliper and repeat until all brakes are bled.
Check the brake fluid level in the master cylinder frequently during the process and top off as needed.

4. Inspect and Replace Components if Necessary

If air cannot be bled out or leaks are found, inspect the brake lines for damage and replace as needed.
If the master cylinder or brake booster is faulty, remove and replace them following the manufacturer's service manual for proper torque specifications and installation procedures.
