Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Socket set, brake fluid, clear tubing, container for old brake fluid, OBD-II scanner.
Safety Warnings: Always wear gloves and safety glasses when working with brake fluid.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid master cylinder.
Remove the cap and check the fluid level; if low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the cap securely.

3. Inspect Brake Lines and Components

Visually inspect all brake lines for signs of wear, corrosion, or leakage.
Check brake calipers and wheel cylinders for fluid leakage.
Tighten any loose connections if needed.

4. Bleed the Brakes

Attach clear tubing to the bleeder valve on the caliper.
Place the other end of the tubing into a container to catch old brake fluid.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to let air and fluid escape, then close the valve before your assistant releases the pedal.
Repeat this process until no air bubbles are seen in the fluid. Start with the caliper farthest from the master cylinder (usually the rear passenger side) and work toward the closest (front driver side).

5. Inspect Brake Pads and Rotors

Remove the wheel to access the brake assembly.
Check the thickness of the brake pads; replace if worn below the manufacturer's specifications.
Inspect the surface of the rotors for scoring or warping; resurface or replace if necessary.
