Brakes problem

SOURCE: 98 caravan no abs

sounds to me if you replaced all of that than the power booster is sticking

SOURCE: front brakes stick on

either your calipers are sticking and need replacing. OR the hoses have failed internally. and need replacing.. very rare but possible the master cylinder is not allowing the fluid to return usually caused bu a booster failing and causing some down travel in the master cylinder. I'd start by raising the front end up. appling hard brake pressure. turn the tire.. then loosen the brake bleeder to check for pressure. if the bleeder sprays fluid and the brakes release forget the calipers. if they are still tight then replace the calipers. pump them up again if they released.. and break the line free at the master cylinder. if they don't release then replace the hoses..

It sounds like you should check for power at brake pedal switch. Hook up a test light to the switch and press the brake pedal. If the light does not go on and you have power in the wires to the switch then the switch should be replaced.
I hope this helps you out

^ Turbo Cars have Lots of Vaccum, Where did you ever get this idea from. I have personally converted 10+ Turbo Buicks to Vac brakes.

Make sure the check valve is okay at the booster. but it does sound like you have a bad booster.
Also, did you change the brake pedal to a Vac brake pedal?
They are not interchangeable.

Also, you should not have drilled the plenum, you can get a vaccum block to replace the plastic one on the top of the plenum with a vac brake port.

SOURCE: 2004 Chevrolet Aveo Brake lights not working

A couple of days ago my brake lights on my 2004 Chevy Aveo wouldn't work, so I attempted to remove the lamp covers to check the bulbs. Also, before this my shifter would get stuck in park and could only be released by pressing the unlock gadget next to the shifter. Back to the brakes...Well, you open the trunk and remove the two screws just like the manual said, but it was very hard to pull off. There's 2 prongs holding the other half of the light on. The lamp will come loose by prying it (very hard). You think the cover will break, but it'll come loose. The bulbs were all OK.

After much frustration and internet info, the STOP LAMP SWITCH, GM#96436331 ($9.30 at Chevy dealer), which is located under the dash and has contact with the brake pedal, was defective. Once replaced, both my brake lights AND SHIFTING problems were cured. So if the brake lights suddenly don't work or you have problems getting the vehicle out of park, check the switch by pushing the prong (end that has contact with brake) of the switch in and out. If it doesn't retract smoothly...that's the PROBLEM. Good Luck.
