Vibration in brake pedal
I jus put my new wheels on they are 18x7.5 well after putting them i have noticed a slight vibration in the brake pedal when im goin over 45mph and i step on the brake, it almost seems like the rotor is to small for the rim. can someone help me with this or give me some advice, i dont want to take it back to the dealer cuz i dont want them to void warranty cuz i put diff wheels on it. thanks

in this case ill put the originals back on ,it wasnt doin it before i put the wheels on, the rims are balanced. with no locking lug. it only does it when i brake, when im driving its fine.

Without looking up the actual number, 100 lbs. ft. should be safe. You can have any number of possible problems with different wheels/tires. Wheel and/or tire runout comes to mind along with balance. Someone suggested putting your original wheels and tires back on. That would be a great diagnostic tool to at least eliminate the rotors.

Also on an empty clear road you may wish to pull the hand brake on, GRADUALLY. It will help to determine location of problem.......rear in this case.
Also, heard the little retainer washer on the rear drums are causing some problems.....not allowing to machined surfaces (wheel and the drum)complete contact.
The hub and outside drum surfaces, according to GM, should be wire brushed BY HAND, if any appearance of rust, corrosion, dirt is apparent....otherwords cleaned well.
