Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety gloves and goggles for protection.

2. Remove the Old Brake Fluid

Use a turkey baster to siphon out the old brake fluid from the reservoir.
Dispose of the old fluid according to local regulations.

3. Flush the Brake System

Locate the brake bleeder screws on each brake caliper (front and rear).
Start with the wheel furthest from the master cylinder (usually the rear passenger side).
Use a brake bleeder kit or a clear tube attached to the bleeder screw.
Open the bleeder screw slightly and have an assistant press the brake pedal gently; watch for fluid to change color and become clear.
Close the bleeder screw before the assistant releases the brake pedal.
Repeat this process for each wheel, ensuring the reservoir is kept full of fresh brake fluid during the process.

4. Refill the Brake Fluid Reservoir

Fill the reservoir with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).
Ensure the fluid is at the correct fill level marked on the reservoir.

5. Final Checks

Check for any leaks around the brake system.
Test the brake pedal feel to ensure it is firm and responsive.
Dispose of the used brake fluid properly.
