grinding dayton calipers to fit 15"rims?

joesolo71 · 12-30-2012, 05:53 AM

Have a 79 hp dana 60 with Dayton dual piston calipers. Can these calipers be ground down to fit 15" rims? I have seen and read a lot of info on grinding calipers but none were daytons. They actually look lower profile than the ones I've seen ground down. They don't wrap over the top of the rotor but they do seem pretty long. Anyone ever tried to fit 15's over these?

I ran 15's with dual piston calipers on my rig only way for it to work is getting wheels with a 2.75" back spacing. No grinding necessary.

I guess you could get 1" spacers and stock wheels would work.

Awsome, they look just like mine. Thank you.
So your saying 2.75 bs and i can fit 15" steelies on it. Cool. If i wanted more backspacing i would have to do some grinding then. Do you think 2.75 bs won't put to much stress on the wheel bearings? How far did your wheels stick out. I'll be running 35" 12.5 r15 tires.

It looks like you did your own break refurbish/rebuild. That's what i would like to do. Where did you find the new parts?

If you want more backspacing that would require you running a 16" wheel or bigger. I had no premature bearing wear/failure. With 15x10's the tires stuck out 2 inches from the fenders with 35x12.50's. I ran 44's with the same wheels and thats when you start burning out bearings and snaping knuckles at the ball joint.

I got all my parts from NAPA Auto

i really appreciate all the great advice. One more thing. Did you use compressed air to remove the pistons and do you need special connectors to do this?

**badass1tonf100** · 01-01-2013, 10:31 PM

Pistons are easily removed. pull the silcone/rubber boots on the piston and the cups slide right out. only speciality tool you need is a brake hone.
