Hi all, I change the back brake caliper, now I've got no brakes, I've used an ezzebleed kit 2 bleed them 4 times, and just took it to ats types and let them power bleed it, still no peddle and hardly any brakes, I kid at ats said he thinks its the master cylinder, but I've only changed the brake caliper, I don't touch the cylinder and don't think in wood just pack up wood it ?, any advice I'm pulling my hair out again, why carnt I get a peddle ? All the air seems 2b out. Please help some 1, thanks.
