brake shudder?

[Kendog013]

i got a 97 grand am....just had the front struts replaced by goodyear, new tires on the car, they aligned the wheels and also put new bearings on the rear wheels, and it runs very smooth at high speeds, except now anywhere over about 65mph pushing the brake pedal produces noise and the steering wheel and entire front end shudders all over the place, i found the pins in the brake caliper FR side were loose today....any suggestions would be appreciated, i have abs brakes too

I would say warped rotors as a posibility.

i heard about that, but it didnt do it before i took in to goodyear, and that was only like 2 weeks ago, its been doing it since. it doesnt always shudder either, usually only when u take it above 75mph....im thinking maybe a problem with the abs...
