As I said, I have a laazzzy brake pedal in my '91 Sonoma. It just doesn't really want to come back up...like its tired or something. Brakes work OK and whatever is causing it doesn't trigger an error code from the ABS, but I'm getting really tired of driving around with my brake lights on half the time. I'm wondering if any of you brake techs have seen this before and know what causes it. I'm thinking it either the booster (1st choice) or a very small vacuum leak behind the dash (2nd choice) that isn't big enough to throw a code yet. I hate to just throw parts at it, and GM made those vacuum hoses so short they are a real pain to get at. I have recently replaced both front calipers, rotors and pads along with the master cylinder.

This is the "ZT" model booster with ABS just on the rear wheels.

Thanks very much for any ideas you may have!

Could the brake light switch be out of adjustment ??
I had a 88 Silverado that would do the same thing. Replaced the switch ... problem solved ... shot in the dark maybe ... maybe NOT ...
