Had rotors milled under warranty and replaced completely after warranty and now they're shaking again. My last GM.
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)

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.
