My brakes, at under 200 miles on the odomter still - from day one, seem to stick, when I come to a stop - in other words - it slowly stops without me even stepping on the brake pedal, but only once (initially) - is it cause its new or am I having a brand new car/ brake problem developing? I have noticed hesitation under 1000 rpm , when taking off from 1st as well .. I have to give it some gas, or it will start to shake real bad ..(the car, in general I am saying) I have been babying it since I picked her up, at 10 miles. Something I didn't notice until I got home.

No problem.

Bring her in to the dealer and they'll replace the booster and seal...

PS. Don't try to duplicate in reverse /phpBB/images/smiles/icon_smile.gif its much worse...

Sticky brakes was a well known problem last fall. A number of vacuum boosters were made with worn-out (out of spec) tooling which would not let the brake pedal fully return up after braking. It was most noticeable after running the engine over 3000 rpm and soon or later braking. I had my booster replaced last December at about 1100 miles and I have had no more problems since. I now have over 3400 miles. You can use your right foot to return the pedal to the full up position and you should immediately realize that the brakes are no longer dragging. This should pretty much confirm that the problem is your booster.

Good Luck

Yes thanks guys - I am expecting the part tomorrow ... and an installation the following day - I hope this fixes it - because some Baer rotors and new pads are going in, and wanna fix one problem first so they cannot blame it on the new rotors /phpBB/images/smiles/icon_wink.gif

Just the other day, I was in reverse and went backwards at about 10mph and i guess i must have put some pressure on the brakes to start slowing down and this pulsing/jerking feeling went thru the entire car like the brake calipers were grabbing the rotors in a weird manner. Much worse then the feeling of deceleration going forward!

N4C5S... was that the type of feeling you got in reverse?

This is really pissing me off now cause when I took my car to the dealer MONTHS ago, they said that my car had updated BOOSTER and that my vin wasnt in the range of cars they had issues with. But ROBNYNJ posts that he's got the brake issue and getting his done and he JUST GOT his car. Ugh!

Can anyone please get and post the offical TSB on the booster issue.

HI there,
I dont know of the build dates, as this particular bulletin is for the 01 models only.
I tried to find out but I have no information. Sorry I could not be of more help, c4c5

robnynj,

Glad to hear you got the problem fixed. Did your dealer ever show you a TSB or something similar? My car goes in this evening and I want to have as much info as possible. Thanks.

I dropped my car off this morning at the Chevy Dealership other than the first one that told me my car had no problems and will see what they do and update you guys that are interested.

Their guys have told me they have replaced quite a few so far. And if that's the case with mine, I'm gonna rip into that other dealership starting with a call to Chevy Customer Service.

Update...

The rep called me at home verifying I had the brake issue and that the car needs to sit overnight while they get the part.

He labeled the car as disabled and offered me a car but I have a daily car.

I dont like the idea of my car sitting anywhere overnight but I want this thing taken care of once and for all.

Great ... you all need to have it fixed - anyways, the correct bulletin # is 01-05-22-002 @ 178.86 charge - covered by GM minus fluids and labor, if any needed.

Well friday I was backing up and the brakes seemed to apply themselves. It was quite the shock as I have 3400 miles on the Z now. It happened again on saturday and I took it to the dealer on monday night. So It will be about a week before I know what the fix is but someone at the dealership did mention the booster valve. Ill update as soon as I get it back.
