Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect Brake Fluid

Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect the condition of the brake fluid for contamination.

3. Check for Leaks

Visually inspect brake lines, hoses, and connections for any signs of fluid leakage.
If leaks are found, replace damaged components as necessary.

4. Brake Pad and Rotor Inspection

Remove the wheels using a socket set to access the brake components.
Inspect the brake pads for wear; replace if they are below the manufacturer's minimum thickness.
Check the rotors for scoring or warping; replace if necessary.

5. Test Brake Booster

With the engine off, press the brake pedal several times to exhaust vacuum.
Start the engine while applying light pressure on the brake pedal; the pedal should drop slightly indicating proper booster function.
If the pedal does not drop, check the brake booster for vacuum leaks or failure.

6. Bleed the Brakes

If air is present in the brake lines, bleed the brake system to remove air.
Use a brake bleeder kit or have an assistant press the brake pedal while you open and close the bleeder valves on each brake caliper, starting from the furthest from the master cylinder.
