Who knows if the 1998 Chevy Blazer has disc brakes in front and rotors in the rear or rotors all around?
Some versions had rotors all around, but 99% of these trucks had
rear drum brakes.,,,,,,,,,,,disc and rotor brakes are the same
thing, they are the ones that are squeesed from both sides with
pads and A calliper, DRUM brakes are the ones that have "shoes" on
the inside pushing outward.Hope this helps, Jamison.
