I'm Awesome
I have a 1988 C1500 RCSB. The early year GMT-400's in this configuration come with the JB3 brake option. The JB3 brakes have 1.03" thick rotors unlike all the other brake options that have 1.28" thick rotors. Rotor diameters are the same. JB3 also comes with tiny 2.5" piston front calipers vs the 2.95" front calipers of the JB5/6 or the 3.15" calipers on the JB7. I'd like to put the JB7 calipers on my tiny little rotors for more stopping power. The 0.25" difference in rotor thickness is well within the wear thickness of a new set of pads. Is there any reason why this wouldn't work?
