Pontiac Grand Am Brakes

chergibchergib Posts: 1
I am trying to sell my 2002 GT1. Beauty of a car, but the sale was held up today because of a grinding noise when the potential buyer used the brakes. Now, I have been living with this for quite sometime; and have had it in the shop for grinding while braking & turning (under warranty - lucky me!) and the tires were replaced because there was a "bulliten" on the tires, and also at 16000 mi the pads were replaced and rotors resurfaced in the front only. So what I need to know is does anyone else have grinding brakes? :confuse:

    My 2002 GA does the same thing. I bought it last July with 25,000 miles on it and the salesman said they put new brake pads on it when I bought it. I have not had it looked at though.

    I bought my 2003 grand am se in april w/ 32,000 miles on it. Told the dealership about the grinding brakes they told me it was just the usual grand am brakes. Another friend of mine her dad said that it is the titanium they use now days.

    I knew a dude who had 99 model, and nothing but noisy-grinding problems with front brakes/rotors and wheel bearings every 10-20k Miles. Several times replaced entire sets. They are NOTORIOUS for it. This car is a disaster. Run away. Not mentioning antifreeze penetration into engine oil (cracked gasket), belts failing and myriad of electr-ical/onic problems.

    Not much had really changed with this car over the years, mostly its ugly cladding. That's why they discontinued it, because its name was (is) synonymous with low quality, UNRELIABLE junk priced in same range as 10 times better Hondas, Toyotas, Nissans and Mazdas.
    G6 is its replacement. It is loosely based on German Opel, but with too much of Grand Am legacy, especially seemingly same engines and transmission (old fuel thirsty pushrods.)

    Yes, I had grinding brakes and took it to Belle Tire. They installed the rotors incorrectly. The rotors sit on some sort of pin and they left that peice out. I took it to Tire man and had the brakes fixed correctly and what a difference! I also got a refund from Belle Tire for them not installing the brakes right the first "three times" I had it there for repair. Make sure the rotor is sitting on some sort of Pin/Bracket. :)

    Check to make sure the rotors are installed properly. See other email.
  • Any one help? My 2001 grand am brake dummy light is on. Nothing appears wrong with braking. The cruise won't work , I think they are related perhaps a safety circuit? the cruise switch light won't even come on.
  • :P Trish – my sexy 97 Grand AM Coupe – just wont stop when I tell her to.

    Every morning, early in the morning, after rolling down a hill on the way to work, I need to stop. Usually, I roll through the stop because the girl’s breaks (like an anti-lock thing kicks in) grip and release until I’ve pressed her break pedal to the floor and her legs, sorry, breaks finally grip and hold.

    Trish will also play these games RANDOMLY during the day and night. She usually likes to tease me when I’m parking, or when stopping at a traffic light.

    We have had this problem for three years. There have been many mechanics in our life, but none that could provide us the diagnosis we need for a healthy relationship.

    Usually, the mechanic will rework the breaks, which does not solve our problem. We’ll go in for a follow up, only to be told that we are healthy and he/she can’t see anything wrong with Trish.

    So now I’m wondering, is it me? Am I pressing to hard on her pedal?

    Symptoms:

    -Heavy pulsations (break-release-break-release) until pedal is pressed to with all my might
    -The pulsations are very aggressive/serious/loud, very scary for passengers
    -Always in the morning at same intersection, and randomly throughout the day.
  • I have an 05' GA, and I had my brakes done last Oct. at a local dealership. Recently, I started getting this really bad grinding crap going on. So I took it to Merlins for an inspection. The tech. told me that Pontiac put my brakes on wrong, and that my calipers were locked in one position. Only one brake pad on each of the front axles were working, making my rotors work more, and causing them to overheat. So I need Brakes, Calipers, and Rotors($400).
    The problem is, the dealership is going out of business, and I can't get a hold of anyone. Do you think it's possible that another Pontiac dealership will honor the Pontiac brake warranty? :cry:
  • hi! i am desperate for some help here. i have a 96 grand am that has become a massive money pit. now the brakes seem to lock up -well the whole front end...whenever its wet or been sitting. obviously a little dangerous!!i cant just start fixing things because i dont know where to begin...could it be a sensor or my abs or shoes pads....anyone hear of this? help me please!!!!!!!!

    Do you mean that you put it in drive but it won't move? If so, are you sure that it's the front brakes?

    Could be contaminents in the brake line. This could restrict the fluid flow to from the master cylinder.

    How dirty is the brake fluid in the reservior?
    More details needed.......

    First off, I wouldn't pay 400 for any kind of brake job.
    If the cars brakes were still working, except for the grinding, your calipers are fine. they need to be replaced when they leak or start rubbing.
    You can bypass the rotors if you want too depending on how long they were grinding. Anything more than a couple of days, they need to be resurfaced/replaced.
    Sounds like a load of crap from merlins.
    I don't even know how you could put the brakes on the wrong way.
    The grinding noise is from safety clips on the back of the brake pad to let you know it is time to change them.
    When the pad gets to low, the clips start rubbing against the metal rotor and you get the grinding noise.
    These clips dig into the rotors and cut them up.

    If only one brake pad was working, the car wouldn't stop!!!!! Brakes work by putting pressure against the rotors on both sides like a vise to slow the car down.
    the harder you press the brake pedal, the higher the pressure is against the rotors.
    And unless cows started jumping over the moon, Calipers are always locked in one position, it's the rotor that spins freely.

    Your getting taken for a ride!!!!!!!!!!!!Run fast
  • no it wiil move but it jumps and locks up when io go to brake.
  • going to check but how would wet weather affect this?
  • Hi, has anyone run into a problem of a noise when braking, driving at low speed (30 miles or below) or turning. The noise sounds kind of like dogs barking. The rotors and brakes have been replaced recently (but the noise preceded the replacement). When I first replaced the parts, the noise went away for about a 1000 miles but has returned. We took the new brakes off and cleaned them (thinking it was dust). The noise went away but again came back after about a 1,000 miles. The car is a 2001 and only has about 36,000 miles on it. A few mechanics have looked at it but no one can figure out what the noise is.
    Thanks!
    :confuse:

    Check the surface of the rotors. They could also be warped. Also check the wheel berings. You may also want to look at the calipers to make sure they are square on the rotor and the shoes are on correctly and seated all the way in.

    You should also look at the mounting bolts and make sure they are not bent. They are cheap to replace.

    Hope that helps
  • hi. i have posted before but am hoping someone can help me. i have 96 grand am se and am having trouble w/ the brakes. they seem to lock in the front end if there is any moisture in the are. they dont lock up if its dry out. the tires lock up and i kind of loose control. i dont even know where to start because its only when its wet out...........any help would be appreciated.
  • Thanks for your suggestions. I actually went online and found the TSB reports for my model...turns out that there is something with the tires...if I inflate them more than is prescribed the noise goes away...very strange! I'm actually going to get new tires so this issue should disappear.
  • Lately when I start my car in the morning to, I have to press unreasonable hard on the brake pedal to get the brakes to engage. After that they seem to work fine, however the brake pedal still feels a bit "stiff". I've check the brake booster function by turning the car off and pumping the brakes up until the pedal no longer moves. So it seems like the booster is working ok. I also don't think it is an engine vaccum leak, because I don't get any irregular engine shuddering or sudden jump in RPMs when the brake pedal is pushed. Also this problem only seems to happen when it gets chilly (40 degrees) outside (this problem did not occur during the summer). The only thing I can think that it may be is air in the brake lines or a bad brake booster check valve.

    Does anyone have any suggestions on what might be causing this problem, because I'm taking it in to the dealership tomorrow to have it looked at.
  • I recently have been hearing a sound in the front of my car that sounds like a manual upshifting and downshifting when I accelerate and decelerate, respectively. I don't have a manual car. I was told it might have been the wheel bearing, so I took it to a mechanic and he didn't hear anything when he checked them.

    Last week, I was rearended from behind about about 5 miles and hour. No damage, but when I was driving home, my ABS light, Trac Off and Service Vehicle Soon (not the Service Engine Soon) lights all came on. They come on now at sporadic intervals after I start up the car ranging from after 25 mins of driving to right when I start the car, but once they go on they remain on until I shut the car off.

    I took it to Auto Zone and had them hook it up to their computer but there were no codes. They also tested the Charging System. Then I took it to a mechanic and still no codes. Both places tried with the car and and off to test the codes and they couldn't figure out what was wrong.

    I then took it to the Pontiac dealership and they told my it was most likely my Hub and Bearing Assembly and it would cost $400. (But the mechanic couldn't hear anything wrong with the bearings before.)

    I tested a theory today (it just snowed) and hit the brakes. The lights weren't on at the moment and I could feel the ABS working. A few seconds later, the lights were on and when I tried them, the ABS didn't work.

    Can anyone tell me what's wrong? Is it really my hub/bearing assembly or something else. I don't want to pay $400 if it's just wasting my money.

    Thanks.
