Brake Fluid Mix-Up

Q: I accidentally poured a small amount of windshield wiper fluid in my brake fluid container. What do I have to do to fix it? What is going to happen? My car is only a year old.

A: Your braking system will need to be flushed (all of the brake fluid completely removed) and refilled. If left in the braking system, the wrong fluid could end up ruining the brake calipers, brake master cylinder, rubber brake hoses, and other brake components – leading to brake failure. To be on the safe side, I would have the vehicle towed to your dealer, tell them what you did, and get their recommendation so you don’t void any warranty items.
