Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level; if low, refill with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Check the fluid condition; if dirty or contaminated, proceed to flush the system.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, brake fluid, wrench.
Start at the furthest wheel from the master cylinder (usually the rear passenger side).
Attach the bleeder kit to the brake caliper bleeder valve.
Have an assistant press the brake pedal slowly while you open the bleeder valve.
Close the valve before the pedal reaches the floor and instruct the assistant to release the pedal.
Repeat until no air bubbles are visible in the fluid, then move to the next wheel.
Continue this process for all four wheels, ensuring to keep the master cylinder topped up.

4. Inspect Brake Components

Visually inspect brake pads and rotors for wear; replace if thickness is below specifications or if there are deep grooves.
Check brake lines for any signs of deterioration or leaks and replace if necessary.

5. Test Brake Booster

Turn on the engine and apply the brakes; the pedal should feel firm.
If the pedal sinks to the floor or feels excessively soft, replace the brake booster.
