FeelthePathos95 Posted June 2, 2016 Share Posted June 2, 2016 So the other day I went to drive my '94 SE and noticed that brake pedal was suddenly very stiff. Had to just about stand on it to bring vehicle to stop. And then when I pulled over and put it in park if I then applied pressure to the brake pedal the engine idle would increase. If I then released pressure on the brake pedal the idle would drop back down below normal and the vehicle would nearly die before returning to normal idle. Repeated this several times to verify and it happened every time. Thoughts about what I've got going on? Link to comment Share on other sites More sharing options...
Rebelord Posted June 2, 2016 Share Posted June 2, 2016 Brake booster line broken or booster itself is bad. Sent from my SM-G920V using Tapatalk 1 Link to comment Share on other sites More sharing options...
FeelthePathos95 Posted June 2, 2016 Author Share Posted June 2, 2016 Wondered about booster. Just confused as to how that would have any effect on idle. Link to comment Share on other sites More sharing options...
Rebelord Posted June 2, 2016 Share Posted June 2, 2016 Because it works off vacuum. 1 Link to comment Share on other sites More sharing options...
Kingman Posted June 4, 2016 Share Posted June 4, 2016 Bad booster or vacuum line going to it. When they go bad they create a large vacuum leak, instead of drawing vacuum into the diaphragm to give assist it just leaks out Link to comment Share on other sites More sharing options...
