Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery for safety.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Instructions:
1. Open the hood and locate the master cylinder reservoir.
2. Check the brake fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4).
3. Secure the cap back on the reservoir.

3. Inspect and Repair Leaks

Tools Required: Wrenches, brake cleaner, rags
Instructions:
1. Visually inspect all brake lines and hoses for cracks or leaks.
2. If leaks are found, replace the damaged brake lines or hoses.
3. Clean any spilled brake fluid with brake cleaner to prevent damage to paint.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, brake fluid
Instructions:
1. Start with the wheel farthest from the master cylinder (usually the right rear).
2. Attach the bleeder kit to the brake caliper bleeder screw.
3. Have an assistant press the brake pedal while you open the bleeder screw to release air.
4. Close the bleeder screw before releasing the brake pedal.
5. Repeat this process at all four wheels until no air bubbles are seen in the fluid.

5. Inspect Brake Components

Tools Required: Torque wrench, socket set
Instructions:
1. Remove the wheel to access the brake caliper and rotor.
2. Inspect brake pads for wear; replace if below manufacturer specifications.
3. Check rotors for warping or excessive wear; resurface or replace as necessary.
4. Reassemble the wheel and torque lug nuts to factory specifications.

6. Test the Brake Booster

Tools Required: None
Instructions:
1. With the engine off, press the brake pedal several times to deplete the vacuum.
2. Start the engine while pressing the brake pedal; it should drop slightly if the booster is functioning properly.
