Quote: Getting that type of pressure from a 1 1/32" bore master cylinder will require a VERY HEAVY FOOT... more than most people are used to or expect.
Do you mean 1 1/8"? They do require a heavy foot. I'm running one on my Duster and will be changing to a smaller bore. The common bore sizes found for replacement a-body master cylinders (Referencing NAPA) are:
15/16" - Power disc/drum 1 1/32" - Manual disc/drums 1 1/8" - (Common on trucks, including manual)
The interesting thing is, MP brakes says larger bore MC's are for power brakes, whereas Mopar seems to be opposite.
