Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, rags
Check the brake fluid level in the master cylinder. If low, add recommended brake fluid (DOT 3 or DOT 4).
Clean the cap and surrounding area before opening to prevent contamination.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Locate the brake bleeder valve on each wheel's brake caliper.
Attach clear tubing to the bleeder valve and place the other end in a container.
Have an assistant pump the brake pedal several times and then hold it down. Open the bleeder valve to allow fluid to escape, then close it before the assistant releases the pedal.
Repeat until fluid runs clear without bubbles, moving from the wheel furthest from the master cylinder to the closest (right rear, left rear, right front, left front).

4. Inspect Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel to access brake components.
Inspect brake pads for wear; replace if less than 3mm thick.
Check calipers for proper movement; lubricate sliding pins if necessary.
Ensure rotors are not warped; replace if necessary.

5. Test Brake Booster

Tools Required: Vacuum gauge (optional)
With the engine off, pump the brake pedal until it becomes hard.
Start the engine; if the pedal drops slightly, the brake booster is functioning correctly.
If it remains hard, the booster may need replacement.
