Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Wear safety glasses and gloves for protection.

2. Inspect Brake Fluid

Tools Required: Brake fluid tester, clean cloth
Open the hood and locate the brake master cylinder.
Check the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect the fluid condition; if it appears dark or contaminated, consider flushing the brake system.

3. Check for Leaks

Tools Required: Flashlight
Visually inspect brake lines, calipers, and wheel cylinders for any signs of fluid leakage.
Clean any spilled fluid with a cloth and monitor for reoccurrence.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container
Start at the wheel farthest from the master cylinder (usually the right rear).
Attach the clear tubing to the bleeder valve on the brake caliper.
Open the valve and have an assistant press the brake pedal; watch for air bubbles in the fluid.
Close the valve before the pedal is released, then repeat until no bubbles appear.
Move on to the next wheel and repeat the process.
Ensure to maintain fluid level in the master cylinder during the process.

5. Test Brake Booster

Tools Required: None
With the engine off, press the brake pedal several times to deplete the booster.
Start the engine while pressing the pedal; if the pedal sinks slightly, the booster is functioning correctly.
If the pedal does not sink, the brake booster may need replacement.
