Solution

1. Preparation

Gather tools and parts required for the brake fluid replacement.
Safety gear (gloves, goggles) should be worn.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Remove Old Brake Fluid

Step 1: Open the brake fluid reservoir cap.
Step 2: Use a turkey baster or siphon to remove as much old fluid as possible from the reservoir.
Step 3: Dispose of the old brake fluid according to local regulations.

3. Flush Brake Lines

Step 1: Starting with the wheel furthest from the master cylinder (typically the passenger rear), loosen the bleeder valve on the brake caliper using a wrench.
Step 2: Have an assistant press the brake pedal slowly to push old fluid through the system.
Step 3: Monitor the fluid color in the tube connected to the bleeder valve until it runs clear; then close the valve before releasing the brake pedal.
Step 4: Repeat this process on each wheel (passenger rear, driver rear, passenger front, driver front) in the same order.

4. Add New Brake Fluid

Step 1: Fill the brake fluid reservoir with new, manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Step 2: Replace the reservoir cap securely.

5. Final Checks

Step 1: Check the brake pedal feel; it should be firm and responsive.
Step 2: Inspect for any leaks around the brake lines and connections.
Step 3: Test drive the vehicle at low speed to ensure proper brake function.
