Solution

1. Preparation

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

2. Check Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
If the fluid is below the recommended level, add the appropriate brake fluid (DOT 3 or DOT 4).
Inspect the reservoir cap for proper sealing and replace if damaged.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench for bleeder screws, brake fluid.
Start with the wheel farthest from the master cylinder (passenger side rear).
1. Attach the brake bleeder kit to the bleeder screw on the brake caliper.
2. Have an assistant pump the brake pedal several times and hold it down.
3. Open the bleeder screw to release air and fluid, then close it before your assistant releases the brake pedal.
4. Repeat until no air bubbles are visible in the fluid.
5. Move to the next wheel (driver side rear), then passenger side front, and lastly driver side front.
Ensure the master cylinder reservoir remains topped off during this process.

4. Inspect and Replace Components

If bleeding does not resolve the issue, inspect the brake pads and rotors.
- Remove the wheel and caliper to visually check the condition of pads and rotors.
- Replace worn-out pads or damaged rotors as necessary.
Check the brake lines for damage or corrosion and replace any compromised sections.

5. Test Drive and Final Check

After repairs, perform a test drive to check brake responsiveness.
Re-check brake fluid levels and inspect for leaks after the test drive.
