Solution

1. Preparation

Tools Required: Brake fluid, brake bleeder kit, wrench set, jack and jack stands, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off before starting.

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it is below the minimum mark, add the appropriate brake fluid type as specified in the owner’s manual.
Inspect the reservoir cap for damage and ensure it seals properly.

3. Check for Leaks

Inspect brake lines, hoses, calipers, and wheel cylinders for any signs of fluid leaks.
If any leaks are found, replace the damaged components before proceeding.

4. Bleed the Brake System

Tools Required: Brake bleeder kit.
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder kit to the brake caliper and open the bleeder screw.
Have an assistant press the brake pedal slowly while you monitor fluid flow; close the screw before they release the pedal.
Repeat until you see clear fluid without bubbles, then move to the next wheel (left rear, right front, left front).
Ensure the brake fluid level in the reservoir does not drop below the minimum during the process.

5. Test the Brake Booster

With the engine running, press the brake pedal several times to deplete the vacuum.
Hold the pedal down; if it sinks to the floor, the brake booster may be faulty and should be inspected or replaced.
