had a leaking wheel cyl. that didnt help when i replaced it, tech at work said master cyl, that didnt help after i replaced it…this was just out of random after i put bad gas in my car…i let it idle after putting good gas in and then i hop in to take it for a ride, go to stop at the end of my driveway, and where do i go? right out into traffic
ya may have a hung caliper slide or the wheel cyl came off the pad and let go ya need to get it apart and see …your best bet is to bleed the whole car out and make sure ya pushin fluid out of all the bleeders wit some pressure if not ya may have lost the master
just replaced the master, and all of the brakes are under a year old (new cailpers/brackets, all bolts + wheel cyls.) rear shoes could use replacing but i doubt that i would have nothing
the only reason i did one wheel cyl was because the other one was replaced a few months before out of emergency, it was leaking…all of the calipers were replaced at the same time and same with pads/shoes
