Solution

1. Preparation

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

2. Check and Replenish Brake Fluid

Locate the brake fluid reservoir under the hood.
Remove the cap and inspect the fluid level. If low, top it up with the manufacturer's recommended brake fluid (usually DOT 4).
Replace the cap securely.

3. Bleed the Brakes

Tools Required: Brake bleeder kit or clear tubing and a catch bottle.
Start with the brake furthest from the master cylinder (usually the rear passenger side).
Attach the tubing to the bleeder valve and place the other end in the catch bottle.
Have an assistant press the brake pedal several times and hold it down. Open the bleeder valve to release air and fluid; close the valve before the pedal is released.
Repeat the process on each wheel in the following order: rear passenger, rear driver, front passenger, front driver.
Monitor the fluid level in the reservoir and top up as necessary.

4. Inspect and Replace Brake Components (if needed)

Remove the wheel to access the brake components.
Inspect the brake pads and rotors for excessive wear. Replace if worn below manufacturer specifications.
Check brake calipers for proper function and leaks. Replace if necessary.
