Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the brake fluid level. If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or hose, container for old fluid, wrench for bleeder valves
Steps:
1. Start with the wheel furthest from the master cylinder (usually the right rear).
2. Attach the brake bleeder hose to the bleeder valve on the caliper.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve to release fluid and air, then close it.
5. Repeat until clear fluid without bubbles flows from the bleeder valve.
6. Move to the next wheel (left rear, right front, left front) and repeat the process.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads/rotors (if required)
Steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear; replace if the thickness is less than 3mm.
3. Check rotors for scoring or warping; replace if damaged.
4. Reassemble the brake components and tighten to manufacturer specifications.

5. Test the Brake Booster

Tools Required: None
Steps:
1. With the engine off, pump the brake pedal several times to deplete vacuum.
2. Hold the pedal down and start the engine. The pedal should drop slightly if the booster is functioning properly.
