I have a 1998 Blazer and the brakes are making a deliciously crunchy noise. I'm looking to buy both set of brakes and rotors and this is the best/cheapest one I could find. It says these are for a 2WD. I have regular 5 stud wheels, not a ZR2 model. Can I use these?

 

Have you positively determined that it is bad rotors and brakes (calipers and pads) that is causing this? The abs system will rapidly engage and disengage the brakes on each separate wheel during hard braking to compensate for loss of traction causing the pedal to flutter and some noise will result which some people label a crunching type sound. Do your tires have good tread on them still? It could also be that the shims that mediate between contact points where the pads slide on the caliper are not properly greased. Unless you really don't care I wouldn't spend all that money on new brakes if you don't have to.
