Original brakes worked fine for about 50000 miles then heavy shudder on front when brakes applied at highway speeds, pulsating at low speeds unless heavy brake applied. Local oil change repair shop turned rotors and replaced pads on front only. About a year and 25,000 more miles later, same problem. Same shop replaced pads only. This didn't last very long and it was back to doing it again. Same shop turned rotors again and replaced pads on all four wheels. This lasted about one year and same thing, pulsating at low speeds and shudder at high speeds when brakes applied. Vehicle now has 121,000 miles on it and they again wanted to fix it but this time it would take new rotors (can't turn them more than twice) and new pads. They said they would warrant the pads. So for three times in three years I've had brakes done. The problem is excessive heat warping the rotors. I did not let them make the repair because I had another problem with the vehicle and I took it to a Buick dealer. Installed GM rotors and GM pads. Hopefully this will give me a longer fix on the brake issue. I'll let you know a year from now.(Feb. 2012)
I had the brake vibrating problem. I bought new rotors from AutoZone. The rotors didn't have the screw hole to screw to the hub. So I had them double check the part number, and it was the correct one. So I left the screw out, and put everything back together. Miles later when I usually get the vibration, I don't have it now. For some strange reason I believe the rotors being bolted to the hub causes the vibration. So far two years inc brake job later, still using the same rotors.
Front end vibrates sounding like a helicopter when driving. Pulsating from brake pedal.
I am very easy on brakes. I live in flat country, don't tailgate, and don't run up to stop signs/lights then brake at the last moment. The factory set of brakes lasted 75k miles and weren't too bad when replaced but did have the pulsations starting to develop. Pads and rotors replaced all the way around with typical auto parts store "platinum" series. Now at 97k,the pulsations are back. I blamed it on the fact that I now only put 3k miles/year and the rust builds up between drives creating hot spots. That is just a guess.
pluse when breaking service ABS light comes on
ABS Sign keeps coming on, along with repair brake system. Have replaced computer chip in front wheels but still happens. Brakes pulsate when in use. Have replace brakes on this car too many times to count. bad design.
When u hit the brakes, u have pump them like its raining.
Had rotors milled under warranty and replaced completely after warranty and now they're shaking again. My last GM.
We have had the same experience Had the problem since new New rotors only seem to fix the problem for 10000 or less miles before it returns. Seems more pronounce, the more weight the van is carrying. With 4-5 riders at 70 mph, the front end vibrates violently when breaks are applied. Local servicing dealer seems to think that the hubs are worn out. However the vehicle glides effortlessly without the grinding noise associated hub failure. Tires are wearing evenly. Thoughts anyone?
We have had this problem since we first bought the van new. Whenever the brakes are applied the van shudders. We were told it was a front suspension problem that GM was aware of but didn't know how to fix.
