04 Rodeo brake problem

My 04 Rodeo brakes have an intermittent vibration when I press the brakes. At first it was only when I was going at a low speed, but now it does it anytime. When you press the brakes you can feel the vibration in the pedal. It only started after the dealer serviced my car and rotated the tires and checked the brakes. I've been taking it every month for the past 4 months and they still can't find the prob. They say the pads are good. Anyone got any ideas?

the roters are warped or the drive shaft is out of balance.

I'd guess warped rotors, too, but it's a little odd that it occured right after the brake service. I can't imagine they did anything to cause it.

Thats why I wont let anyone near my wheels with an impact wrench and torque sticks when they put the wheels on. The brakes on my mitsu would warp every time they did that. I make sure the service manager writes on the ticket to use torque wrench by hand only for install.

Might be too late now since its been a few months but I usually take it back to them and make them have the rotors and drums turned.

I've been taking my car in ever since they did the check on the brakes back months ago, and have been taking it in nearly every 3 weeks. Tomorrow my car is going back in and hopefully they'll find the problem now. I'll be sure to have them check the rotors, drive shaft, and tell them to only use a torque wrenchby hand only for installation.
