Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Check the brake fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 4).
If the fluid is dark or contaminated, proceed to replace it.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or hose, container, wrench.
Start at the wheel farthest from the master cylinder (usually the right rear wheel).
1. Attach the bleeder kit or hose to the brake bleeder screw.
2. Have an assistant pump the brake pedal several times and hold.
3. Open the bleeder screw to release fluid and air, then close it while your assistant maintains pressure on the brake pedal.
4. Repeat until no more air bubbles appear in the fluid.
5. Move to the next wheel and repeat the process until all four wheels are bled.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads and rotors (if necessary).
Remove the wheel and inspect the brake pads and rotors for wear.
Replace any worn or damaged components as needed.
Reassemble and torque the wheel nuts to the manufacturer's specifications.

5. Test the Brake Booster

Tools Required: Vacuum gauge (if necessary).
With the engine off, pump the brake pedal to deplete vacuum. Start the engine and verify that the brake pedal should drop slightly, indicating the booster is functioning correctly.
