Been going around and around on the internet trying to find a replacement brake fluid cap for a 2014 CX9 (Grand Touring FWD). Mazda apparently doesn't sell the cap by itself, you have to buy the entire replacement reservoir for $300 which is insanity. So now I'm trying to track down a sort of universal cap but nothing from autozone, Napa, O'Reilly fits. I've now tried to go through Amazon and so far no luck. Does anyone has an idea or direction to point me in?

I was afraid of having to go that route, sounds like its gonna be a pain calling around to find a yard that has the car but probably will be the best means to replace the cap at this point. Thank you

 

do you still have the old one?...wonder if you could take a photo and us AI to find one for sale...could maybe find a universal brake fluid reservoir cap at an auto parts store but i would bring the old cap with you...also check ebay

 

I wish I still had the old one, its for a friend's car. She somehow lost the cap, literally has no idea how

Look again . That is a common brake fluid cap available for under 15 buck or less!
