Solution

1. Preparation

Gather tools and parts required for the fluid replacement.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves to protect from brake fluid.

2. Remove Brake Fluid Reservoir Cap

Locate the brake fluid reservoir, typically near the driver's side of the engine bay.
Remove the cap carefully, ensuring no dirt or debris falls into the reservoir.

3. Drain Old Brake Fluid

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

4. Flush the Brake Lines

Locate the brake bleeder valves on each wheel assembly (one at each caliper).
Attach a clear plastic hose over the bleeder valve and place the other end into a container to catch the old fluid.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow old fluid to escape, then close it before your assistant releases the pedal.
Repeat this process until new, clear brake fluid emerges from the hose.
Ensure to check the brake fluid reservoir frequently during this process to keep it topped up.

5. Refill with New Brake Fluid

Once old fluid is completely drained, refill the brake fluid reservoir with the appropriate type of new brake fluid (usually DOT 3 or DOT 4, check owner’s manual for specifications).
Replace the reservoir cap securely.

6. Test the Brake System

Press the brake pedal several times to build pressure in the system.
Check for any leaks around the bleeder valves and the reservoir.
