Think about this, an 11" rotor is the same size brake as a 9" drum brake, but it requires Power to make it work near the same...Chris@whiterhino said:On the Rockwell Axles I use for my chassis we put an old Cadilac caliper on it. It has a build in Manual e-Brake so you don't have to use the disk/ drum combo.
AutoZone part Numbers:
C242 Driver Side
C243 Passenger side
These come off the 1984 Eldorado with the 11" rotor if I remember correctly.
