Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear safety goggles and gloves.

2. Check Brake Fluid Level

Locate the brake fluid reservoir.
If low, add the recommended brake fluid (DOT 3 or DOT 4) until it reaches the full mark.
Inspect for leaks around the reservoir, master cylinder, and brake lines.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench, clean rags.
Start with the wheel farthest from the master cylinder (usually the right rear):
1. Attach the brake bleeder kit to the bleeder valve on the brake caliper.
2. Have an assistant pump the brake pedal several times and hold it down.
3. Open the bleeder valve slightly and let fluid escape until there are no air bubbles.
4. Close the valve, and instruct the assistant to release the pedal.
5. Repeat for the remaining wheels in the order: right rear, left rear, right front, left front.

4. Inspect and Replace Brake Components

Inspect brake pads and rotors:
1. Remove the wheel using a socket set.
2. Check the thickness of the brake pads; replace if they are below the minimum thickness (usually 3 mm).
3. Inspect rotors for warping or scoring; replace if necessary.
If components are worn, replace with OEM or high-quality aftermarket parts.

5. Check and Repair Brake Lines

Inspect brake lines for leaks or damage:
1. Look for wet spots or corrosion on the lines.
2. If damage is found, replace the affected brake line using a line wrench.
3. Bleed the brakes after replacing any lines.
