Solution

1. Preparation

Gather tools: brake fluid, socket set, brake bleeder kit, wrench set, jack, and jack stands.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Address Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
Check fluid level; if low, add the recommended brake fluid type as specified in the owner’s manual.
Inspect for leaks around the reservoir and cap.

3. Bleed the Brakes

Tools Required: Brake bleeder kit
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder hose to the brake bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow fluid and air to escape, then close it before the assistant releases the pedal.
Repeat until the fluid runs clear with no bubbles, then move to the next wheel.
Torque the bleeder valve to the manufacturer's specifications after bleeding each wheel.

4. Inspect and Replace Components

If bleeding does not resolve the issue, inspect brake pads and rotors.
If worn, replace brake pads and resurface or replace rotors as necessary.
Reassemble all components, ensuring proper fitment and torque specifications.

5. Check the Brake Booster

Inspect the brake booster for any signs of failure.
If the booster is faulty, replace it following the manufacturer’s service manual.
