    what kind of rotors? if they are slotted they will growl when you get on them hard.

    98 Buick Regal GS, F body brakes, Caddy STS wheels, tinted tails L36 bottom end, lightly ported heads, 1.95 roller rockers, headers, gen 5 N* 3.0 pulley, FSIC, 42 lb injectors, a BrandonHall rebuilt trans, DHP tuned and AEM water/Meth injection https://goo.gl/gpV5kW

    Yes they are slotted and cross drilled but when I slam brakes there is no sound its just when medium pressure is applied

    as long as its not pulling to one side when braking, id blame the slotted rotors. if really new still the pads might be breaking in still. the r1's i use take up to 500 miles to fully bed in.

    Did you use a torque wrench on the hubs?
