Oldgamer Posted July 7, 2006 Report Share Posted July 7, 2006 Hey, everybody. I didn't visit a forum a while. A lot of changes. Can't see Scotty anywhere. Hope hi is fine. OK, now back to the problem. It's not a big deal, but still... When I release the brake pedal for start driving i can hear the sound and feel vibration on a brake pedal. What it can be? Otherwise, everything is OK. Thanks. Link to comment Share on other sites More sharing options...
Cadillac Jim Posted July 7, 2006 Report Share Posted July 7, 2006 Sounds like a sticking caliper to me. I would have it looked at by someone who knows brakes. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Ranger Posted July 7, 2006 Report Share Posted July 7, 2006 My guess would be a dragging parking brake not fully releasing. You have been gone awhile. "Scotty" is now "Body By Fisher" aka BBF. Link to comment Share on other sites More sharing options...

Oldgamer Posted July 7, 2006 Author Report Share Posted July 7, 2006 Thanks guys. Good "Scotty" is here. Well, I never use a parking brake, so it's possible a sticking caliper. I'm not sure what is it, but I can guess it is a moving piston, and it stocks and vibrates when it's moving. Hmmmm, and what should I do about that? Check all four of them? Change them?

Cadillac Jim Posted July 7, 2006 Report Share Posted July 7, 2006 The brake caliper is to disk brakes what the wheel cylinder is to drum brakes. It has pistons that push the brake pads against the disks. If one sticks, the pad will drag against the disk. Ranger's suggestion about the parking brake is also a good one. Even if you never use it, there might be something there. Whever regularly services your car may be able to clear up your problem with a rag and a brush, or somthing minor like a retractor spring on the parking brake.

BodybyFisher Posted July 7, 2006 Report Share Posted July 7, 2006 It sounds like your caliper might be releasing slowly. Question, are you getting high speed pulsing when you brake? If you are, hold your parking brake down while you are moving to see if its coming from the rear. While the car is in gear it won't engage...

adallak Posted July 7, 2006 Report Share Posted July 7, 2006 Check the caliper bolts and the related rubber bushings. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
Oldgamer Posted July 7, 2006 Author Report Share Posted July 7, 2006 Wow! Just got home and got some answers already! That's fast! No, I didn't feel any vibration when I brake. Only when I release the brake after stop. I guess specially after staying long time. I barely use my car, sometimes it stays weeks. I'm going to New Jersey today, didn't start car for 2 weeks. I will try to look closer for the symptoms. No, I never did my brake (adallak, i remember yours poll ). Only 5 years ago polished front rotors and changed pads. Never had a problems, leaks and never changed the fluid. I'll check parking too. I remember hen I heard that sound I thought that is something from the stearing. But later I felt brake pedal vibration when release and now I think like it's caliper or something like that. I will back from New Jersey sunday evening, hopefully in whole peace.

BodybyFisher Posted July 8, 2006 Report Share Posted July 8, 2006 My front calipers have two rubber bushings in them, if they are worn, dry rotted or damaged I could see the caliper being able to oscillate back and forth. I would determine if its the back or front and inspect the system carefully.
