74/75 Imperial rear disc brake system

[30dodgeboy]

On the 74/75 Imperials with rear disc brakes, are the rear brake calipers mounted ahead of or behind the brake rotors? Anyone have service information on this system? Are the same calipers/pads also used on other applications?

Thanks in advance.

Can't answer your question but welcome aboard. Some members here specialize in your vintage of car and likely know the answer. How about some pics of your ride?

Caliper mounting depends on which side of the car you're on. The Passenger side has the caliper on the trailing side; on the driver's side, it's on the leading side.

Imperial Rear calipers are the same as the front calipers on a Volare (F/M/J cars up to 89). Pads are the same, but the steel tab must be modified on the outer pad (ground out) to clear the rotors.

They are very hard to find parts for, which scares a lot of people away from these.
Nearly impossible parts to find list:

Rotors, Emergency brake shoes (fit inside the rotor "hat") and spring hardware. Rear hoses (the stubby ones).

They are worth the trouble to keep working in my opinion...my 74 Imperials are the best braking cars I've ever owned.

Mr. C: Different axles from the drum rears?

Nope... regular axles. The rotor "hat" slips over the normal axle, like a drum would.

So a drum brake conversation is doable as a Hail Mary Save in a worst case scenario.

Yup, easily done, just transfer everything over and you're set. I don't know how the Imperial Master Cylinder (it's different with equally large resevoirs for both disc systems) would behave...theoretically it should be fine as the resevoir is now double/ triple the capacity needed for drums.

Hmmm... Now all those 74/75 Imps I previously scratched off my list.....
