How difficult is it to access these six mounting bolts for torquing? I do not have a lift. I may want to replace and tighten the bolts myself to ensure it is done to proper specs. Since body shop did not do it properly to begin with, I’m not confident they will do it correctly with new bolts.
I think you are right the brake booster must be leaking internally. I have tried everything else. Yesterday I replaced the check valve thinking it maybe wasn't closing all the way. Didn't really believe it since the booster held vacuum when the truck was off. I even bought an original gm check valve from Rockauto.
That booster isn't even a year old. O'Reilly's lifetime warranty.
I am not looking forward to removing/installing that brake pedal clip again.
Good news is that my truck is running great after the throttle body re-built issues.
Thanks for the support.
