Solution

1. Preparation

Tools Required: Socket set, brake fluid tester, OBD-II scanner, brake cleaner, lint-free cloth.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves to protect yourself.

2. Inspect and Top Off Brake Fluid

Remove the cap from the master cylinder reservoir.
Check the fluid level; if low, add the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Clean the reservoir cap and reseal tightly.

3. Check for Leaks

Visually inspect all brake lines, hoses, and fittings for signs of leaks.
If a leak is found, replace the damaged component (line or hose) and ensure all connections are secure.

4. Brake System Bleeding

Tools Required: Brake bleeder kit, clear tubing, catch container.
Start with the brake furthest from the master cylinder (usually the rear passenger side).
Attach the clear tubing to the bleeder valve and place the other end in the catch container.
Open the bleeder valve slightly and have an assistant press the brake pedal several times until no air bubbles appear in the fluid.
Close the bleeder valve and repeat for the other brakes in the order: rear passenger, rear driver, front passenger, and finally front driver side.

5. Inspect Brake Components

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

6. Reassemble and Test

Reattach the wheel and lower the vehicle.
Pump the brake pedal to ensure it feels firm.
Test drive the vehicle to verify that braking performance has returned to normal.
