1996 Olds bravada brake issues

1996 Olds bravada brake issues
I have a 1996 olds bravada. When you push on the brake the pedal is hard and no stopping. If you pump the brake it will release and quickly pull front drivers side and then will release. Then you hear the antilock kick in. I'm completely confused. Master cylinder, bad caliper, or maybe the brake booster. I'm lost. Please help

RE: 1996 Olds bravada brake issues
What I would do is jack up the car and have someone work the brake pedal to see if each wheel stops and releases on it's own. (checking the calipers) While it's jacked up also check for wheel bearing play as a bad bearing will also cause this issue. If the bearings are good (no slack) I would suspect a bad speed sensor is causing the ABS to kick in. You may need professional help in the way of someone with a scanner that will do ABS systems but I can tell you that it's probably not a MC or brake booster issue.

BTW, if you have recently noticed any extra noise up front (like riding on snow tires) you may have a wheel bearing starting to go bad and that's what's making the speed sensor on one wheel act up.

I am leaving on an extended vacation in a few hours but the other guys can probably guide you once it's narrowed down a bit more.

You may want to post your findings after consulting a local mechanic. We can educate you enough to keep him honest if needed and there may be others who can learn something from the final fix.

Leaving for the airport in 6 hours!
