Performing a brake fluid flush on your 2017 MINI John Cooper Works is an essential maintenance task that helps ensure your braking system remains responsive and safe. Brake fluid absorbs moisture over time, which can lead to corrosion and reduced braking efficiency. Here’s a simple step-by-step guide to performing a DIY brake fluid flush with Everyday MINI.

What You'll Need

  • Fresh brake fluid (check your owner’s manual for the recommended type)
  • A wrench or socket set for bleeder screws
  • A clear plastic tube
  • A catch container
  • Brake bleeder kit (optional but helpful)
  • Gloves and safety glasses

Step-by-Step Brake Fluid Flush

  1. Prepare your MINI: Park on a level surface, engage the parking brake, and remove the wheels for easier access to brake calipers.
  2. Locate the brake fluid reservoir: Open the hood and find the reservoir. Clean the cap area to prevent contamination.
  3. Remove old fluid: Use a syringe or turkey baster to remove as much old fluid from the reservoir as possible.
  4. Refill with fresh brake fluid: Fill the reservoir with new brake fluid.
  5. Bleed the brakes: Starting with the wheel farthest from the master cylinder (usually the right rear), attach the clear tube to the bleeder valve. Have a helper press the brake pedal slowly as you open the valve to release fluid and air. Close the valve before your helper releases the pedal. Repeat until clear fluid flows.
  6. Top off the brake fluid reservoir: Keep it filled to avoid introducing air into the system.
  7. Repeat for all wheels: Move to the next farthest wheel and continue until all brakes have been flushed.
  8. Check pedal feel: Ensure the brake pedal feels firm before driving.

Regularly flushing your brake fluid every two years or according to your MINI’s maintenance schedule will keep your braking system in peak condition. When in doubt, consult your owner's manual or a professional mechanic.
