Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Top Off Brake Fluid

Locate the master cylinder: Open the hood and find the brake fluid reservoir.
Check fluid level: If the fluid is low, add the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks: Look around the reservoir and brake lines for any signs of fluid leakage.

3. Bleed the Brakes

Prepare for bleeding: Use a brake bleeder kit and have an assistant help you with the process.
Start with the wheel farthest from the master cylinder: Typically, this is the right rear wheel.
Open the bleeder valve: Using a wrench, open the bleeder valve while your assistant presses the brake pedal.
Watch for air bubbles: Continue to pump the brake pedal until no more air bubbles come out and the fluid runs clear.
Close the bleeder valve: Tighten it securely before releasing the brake pedal.
Repeat for each wheel: Move to the left rear, right front, and finally the left front.

4. Inspect and Replace Brake Components

Check brake pads and rotors: Remove the wheel and inspect the condition of the brake pads and rotors for wear.
Replace if necessary: If the pads are worn below the minimum thickness or the rotors are warped, replace them with OEM or high-quality aftermarket parts.
Reassemble: Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

5. Test the Brake Booster

Engine running test: Start the engine and press the brake pedal; it should feel firm. If it remains spongy, the brake booster might be faulty and should be inspected or replaced.
