Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Check Brake Fluid Level

Open the hood and locate the master cylinder.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top up with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).

3. Inspect for Leaks

Visually inspect the brake lines and hoses for any signs of wear or fluid leaks.
If leaks are found, replace the damaged lines or hoses.

4. Bleed the Brake System

Attach a clear hose to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and old fluid, then close it before the assistant releases the pedal.
Repeat this process for each wheel until fluid runs clear and free of air bubbles.

5. Inspect and Replace Brake Components

Check the brake pads for thickness and replace them if they are worn down to 3mm or less.
Inspect the rotors for grooves or warping; replace if necessary.
Reassemble all components and ensure all bolts are torqued to manufacturer specifications.

6. Final Check

Refill the master cylinder with brake fluid as needed.
Press the brake pedal to ensure it feels firm and does not go to the floor.
Test drive the vehicle in a safe area to ensure braking performance is restored.
