Rear rotor question for full size axle

I have a Sterling rear and want to move the calipers to the front of the axle, remove the backing plate and caliper mount, and mount some smaller bore calipers.

Problem is the rotor is 1.1 inch thick, calipers are 2x44mm bore. I can't seem to find to find a smaller bore caliper that has the width for the 1 inch rotor. The closest I can find is a rear Dodge 1500 caliper that has a bore of 54x1, for a .86 rotor. I have yet to see if I can fit the Ford rotor inside the caliper with new pads. May have to shave some off the pads, but that's not my favorite option.

My other though was to cut the venting out of the Ford rotor and using a rear Jeep caliper back there, but that will give me like a 3/8 thick rotor or less. ANy thoughts on this? Or a vehicle with a large enough bore for the hub that will be thinner than 1 inch?

Thanks, all.

I know you are a complete total newb, but I'll pull out the important part for you.

I cut the vented part off both my front, and rear axles(steering 609s, with dodge UB outers) So they're solid, Toyota type rotors, with Toyota calipers.

Works fine for me.

But why bother with smaller calipers and peigion holing yourself into exactly this problem?

Sounds like a ruffstuff disc kit with the gm calipers would get him away from the dual piston caliper. Dont know if the kit brackt will fit the later disc axles though.

Hit up gubni,

you want shittier brakes....got it

what is the actual question you are asking cause all I see is rambling?

yes you can make a bracket to mount shittier brakes, and it can orient the caliper where ever you want...yes you can machine the existing rotor in half to make future rotor swaps a pita

Hit up gubni,
I need rear calipers for correct brake bias. The D52s you are recommending are even larger than my rear dual pistons, and no one should run them in the back of anything, short of a monster truck.

BTW, not sure what a peigion is. In fact, I'm sure you made that up.



The proper answer is to get a set of 2-piece Wilwood brake rotors in the thinner width, so I can run calipers that are made for the rear, but those run about $600.

Holy shit.

Not only do they work great.

All you need is a simple psi reducing valve, they about $50 and tune down 50% psi.
