Solution

1. Preparation

Tools Required: Jack and jack stands, wrench set, brake bleeder kit, fluid catch pan, safety goggles.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety goggles for eye protection.

2. Inspect and Refill Brake Fluid

Locate the brake master cylinder reservoir.
Check the brake fluid level; if low, refill it with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect the reservoir cap for proper sealing.

3. Check for Leaks

Visually inspect all brake lines, hoses, and connections for signs of fluid leakage.
If leaks are found, replace the damaged lines or components. Use a wrench to disconnect and replace line fittings as necessary.

4. Bleed the Brake System

Locate the brake bleeder valves on each caliper.
Using a brake bleeder kit, attach the kit to the first caliper (starting with the wheel furthest from the master cylinder).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close it before the pedal is released.
Repeat the process at each caliper until no air bubbles are present in the fluid.
Check the fluid level in the master cylinder and refill as necessary.

5. Inspect Brake Components

Remove the wheel to gain access to the brake components.
Inspect the brake pads for wear; replace if they are below the minimum thickness.
Check the rotors for scoring or warping; replace if needed.
