Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety gloves and goggles.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer's recommended brake fluid (usually DOT 3 or DOT 4).
Inspect the reservoir cap for proper sealing.

3. Check for Leaks

Visually inspect brake lines, calipers, and connections for any signs of fluid leakage.
If leaks are found, determine the source and replace damaged lines or seals.

4. Brake Pad and Rotor Inspection

Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn below 3mm.
Check the rotors for scoring or warping; replace if necessary.

5. Brake Booster Test

With the engine off, pump the brake pedal several times to deplete vacuum.
Hold the pedal down and start the engine; the pedal should drop slightly if the booster is functioning properly.
If the pedal does not drop, replace the brake booster.
