94 olds vert Posted November 19, 2009 Report Share Posted November 19, 2009 My break lights after using my brakes remain on, including the center one. I tried to adjust the that white switch that connects to the brake. It seems like to me the brake isn't returning to where it is supposed to be at, because if I pull up on the brake with my foot the lights go off. Now lets say I pull the car into the garage, shut the door and the all the brake lights pop on. Any ideas? I checked the fuse and its good. The turn signals still work. The lights still work. Checked the bulbs and they are all good. Quote Link to comment Share on other sites More sharing options...
tunerlover3 Posted November 19, 2009 Report Share Posted November 19, 2009 Sounds like a brake switch problem to me. Quote Link to comment Share on other sites More sharing options...
94 olds vert Posted November 19, 2009 Author Report Share Posted November 19, 2009 Sounds like a brake switch problem to me. I've adjusted it several times now, Maybe a new one then? Quote Link to comment Share on other sites More sharing options...
Twenty Posted November 19, 2009 Report Share Posted November 19, 2009 Could be, but I can't say I've got experince with a problem like this. At least they're coming on, period. Quote Link to comment Share on other sites More sharing options...

manifoldsrme Posted November 23, 2009 Report Share Posted November 23, 2009 I noticed on my 90 TGP that someone before me had taken a soft throttle return spring, and wire tied one end to the top of the brake pedal arm, and the other to the front underside of the dash. Works perfect. Pulls the pedal "up" towards you when you let off and lets the brake lights work and turn off. I can take a picture if someone wants to see it.

White93z34 Posted November 23, 2009 Report Share Posted November 23, 2009 if the lights go off after you pull up on the pedal, then you need to unplug the wires on the bottom of the switch and turn it in. so it cinches down closer to the top of the pad on the pedal. then plug the connectors back in Quote Link to comment Share on other sites More sharing options...

94 olds vert Posted December 13, 2009 Author Report Share Posted December 13, 2009 I started messing with this again. If I put the key in the ignition and do not start the car and pump the brakes the lights will work fine. I thought the switch was bad but after doing this the brake lights work. So the switch is probably good. When you step on the brake the switch moves out turning on the brakes, you remove your foot from the brakes and the switch is pushed back in turning off the brakes. I was going to start the car to test the brake lights after I turned the switch, but the damn battery is dead. Quote Link to comment Share on other sites More sharing options...

94 olds vert Posted December 13, 2009 Author Report Share Posted December 13, 2009 So would taking a spring and jury-rig it to the brake pedal be safe? Or just replace the booster. With the car off, pump the brake pedal for like a minute. Then start the car with you foot on the brake pedal just slightly. When you start the car, you should feel the brake pedal drop about 1/4. If it drops, the booster is fine. Should I test it first? Like stated above. Quote Link to comment Share on other sites More sharing options...

94 olds vert Posted December 15, 2009 Author Report Share Posted December 15, 2009 I am thinking its something simple like air in the brake lines, would this cause the pedal not to return to the proper position? Quote Link to comment Share on other sites More sharing options...
cutty Posted December 15, 2009 Report Share Posted December 15, 2009 I'm gonna agree with ken on this, a bad booster wont allow the pedal to return all the way back up. Air in the brake lines would only cause a spongy/soft pedal. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted December 15, 2009 Report Share Posted December 15, 2009 However a out of adjustment brake lamp switch (Especially 88-92 switches!!!) will do the same thing, PMIII or vacuum. Quote Link to comment Share on other sites More sharing options...

White93z34 Posted December 15, 2009 Report Share Posted December 15, 2009 older switches can be bad for it, even pulling back on the brake pedal too hard can cause them to get out of adjustment. 94 olds vert, can you get us a picture of the switch you are adjusting and how it sits on the brake pedal when it is not pressed in?

94 olds vert Posted December 15, 2009 Author Report Share Posted December 15, 2009 I just had the best Idea...I really don't know why I didn't think of this before. I am going to take electrical tape and wrap it around the spot where the connector meets the metal on the brake pad. And that will push that stupid thing in enough and will turn off the brakes.

White93z34 Posted December 15, 2009 Report Share Posted December 15, 2009 you know that the switch is threaded for a reason. just unplug the connector and twist it in towards the brake pedal and it should 100% solve your problem. Quote Link to comment Share on other sites More sharing options...

White93z34 Posted December 15, 2009 Report Share Posted December 15, 2009 Key is to push in on it while you turned it. but good to see that you got it working right either way. Quote Link to comment Share on other sites More sharing options...
