K&R Posted August 29, 2018 Report Posted August 29, 2018 So I have 90' Cutlass Supreme with the Powermaster 3 hydro brake booster. The brakes are firm but when you take your foot off the pedal it does not return back far enough to turn the brake lights off. I was replacing the calipers and went to bleed them and pressed the pedal and I heard a snap. The brake light switch is fine and the hydro boost system is still working properly. Do I need to replace the whole booster? What do you all think? Quote
redgrandprix Posted August 29, 2018 Report Posted August 29, 2018 Pretty sure there is a return spring up high under the dash, most likely what you heard snapSent from my SM-N900T using Tapatalk Go4DaMo 1 Quote
