Very odd problem. For weeks I have been chasing a problem around to fix my sticking and binding brakes. Everything is new. And I’ve swapped out master cylinders and flex pipes etc again with more new kit. The pedal has plenty of free play. The wheel cylinders return no problem, and springs are all correctly orientated, etc...But just noticed that once the pressure builds up, if I yank up on the brake pedal with my foot or hand the pressure releases!!!! You can hear it release.
What the hell could be the cause of this? What’s the fix?
