97 Jimmy brakes

I'm thinking of getting a 97 Jimmy. Anyways, there is a concern I have. Sometimes when you press the brakes you can here a buzzing sound coming from what it seems to be the front driverside. It sounds like an electric motor or something. I was told the ABS sensor, calipers, rotors, and pads have been replaced. Also said he had a diagnostic ran on it and showed no problems. Was worse before replacing the before mentioned parts. The brakes felt a little spongy to me. Had a friend said his Grand Vitara did the same, all it needed was bled. Question is anyone had this problem before, and how did you resolve it?

Sure the sound is brakes and not a vac problem - check all the vac lines on the drivers side for rot from PVC to the reservior and also the large hose to the power brake unit. See if all OK and that the throttle cable is not against the PCV as that gives off a buzzing noise as the retainer clips on the intake always break off so resecure.

I don't think I clarified enough. It almost sounds like a really loud fuel pump, like when you turn the ignition on before starting. It comes on for a couple of seconds then goes off. But it is in the front driver side by the wheel. it doesn't stay on. Does it only when you are pressing the brake. But not everytime. This is with the engine running.

97 Jimmy Brake Problem

I just put new front brake rotors and pads on my Jimmy, which I've done many times before. Immediately after replacing them I went for a test drive. When I apply the brakes I feel a mild vibration/shaking and the right wheel gets hot and the right brake pads squeel. Do I have a bad rotor, if so which one, or do I have a bad caliper? All worked fine before I changed them. Thanks, Keith

Sounds like when you pushed the pistons back in the right one jammed on applying the brakes. Did you grease the slides? Pads must also freely move in the calipers on the metal inserts - if they jam that could be it too - sometimes the caliper bracket gets rust under that metal insert and the pads bind - pop the insert our and remove all rust if binding and use alittle grease on the pad to insert mating points.
The rears are known for binding as the single piston is composite plastic.

Thanks repairdog, that was it! The caliper slides have rubber bushings in them and they were all gummed up. I cleaned and lubricated them and they don't get hot anymore, but now when I brake my Jimmy shakes like crazy. I probably warped the rotors, didn't I?

Most likely with that dragging pad. Get them turned $10-15 each if enough material left or new $35 each and a simple swap out no waiting. Most new ones are warranteed for 1 year so if they do it again you get new ones free with your labor of course.

Yea, the ones I got have a warranty so I'll just take them back and get new ones. Thanks for all your help. If you're ever in NJ look me up and we'll tip a few. Beers not cows. Keith

Where did you find info to help replacing booster? I need to replace mine on my 96 jimmy and can not find diagrams or instructions. My pedal instantly went hard and I replace valve but no change so I'm replacing booster. Can anyone help with instructions or diagrams?  ">

The Haynes manual sold at all stores tells how about $17.
