Solution

1. Preparation

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

2. Inspect Brake Fluid

Tools Required: Brake fluid tester or gauge
Remove the master cylinder cap.
Check the brake fluid level; add fluid if low, ensuring it meets manufacturer specifications (DOT 3 or DOT 4).
Inspect fluid for contamination. If dirty, replace fluid.

3. Examine Brake Lines and Hoses

Tools Required: Visual inspection tools
Inspect all brake lines and hoses for cracks, corrosion, or leaks.
Replace any damaged lines or hoses.

4. Bleed Brake System

Tools Required: Brake bleeder kit, wrench
Locate the bleeder valves on each brake caliper.
Start with the brake furthest from the master cylinder (usually the passenger rear).
Attach the bleeder kit to the valve, open the valve, and pump the brake pedal until no air bubbles appear in the fluid.
Repeat for all brakes in order: passenger rear, driver rear, passenger front, driver front.

5. Test Brake Booster

Tools Required: Vacuum gauge (if necessary)
With the engine off, pump the brake pedal several times to deplete the vacuum.
Start the engine and press the brake pedal; it should feel firmer. If not, the brake booster may be faulty and should be replaced.
