Solution

1. Preparation

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

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Check the master cylinder reservoir for proper fluid level.
If low, add the manufacturer-recommended brake fluid to the desired level.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench
Start at the wheel farthest from the master cylinder (usually the right rear):
1. Attach the bleeder kit to the brake bleeder valve on the caliper.
2. Have an assistant pump the brake pedal several times and hold it down.
3. Open the bleeder valve to allow air and fluid to escape until a steady stream of fluid runs out.
4. Close the valve, and have the assistant release the brake pedal.
5. Repeat for each wheel, moving closer to the master cylinder (right rear, left rear, right front, left front).

4. Inspect Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake components.
Inspect the brake pads and rotors for wear; replace if necessary.
Check calipers for proper operation and any signs of leakage.

5. Check Brake Booster Functionality

Tools Required: Vacuum gauge (if necessary)
With the engine off, pump the brake pedal until it feels hard.
Start the engine with the brake pedal pressed; the pedal should drop slightly indicating the booster is functioning properly.
