I need info on piston diameter for the ITR caliper and piston diameter for the GSR caliper. I'm hoping to get an idea about a possible change in brake force resulting from piston size differences when going from GSR to ITR caliper and rotor upgrade.

Additionally, I'd like to get info on part #s for the ITR ABS controller and the GSR (and other non-ITR integra) ABS computer. I read an article at StopTech on ABS activation w/ bigger front brakes only and want to get an idea if Acura engineers changed the controller unit (NOT the modulator) for the ITR.

Last, does the ITR use a different REAR caliper than the GSR? Some folks have asked this before, but never got an answer from everything I found during a search. I'm wondering if the caliper can be remounted to utilize 10.2" rears w/ 4x100 redrill.

Thanks for any info you can provide.

Surely somebody knows the answer to at least one of these questions, or even a part of one.

 

Get a Helm's manual.

I have the Helm's manual for my '94 GS-R and my '01 ITR. I don't see the piston diameter in the manual, either in the Standards and Service Limits section, or the Design Specifications section, or the sections about the calipers.

Yes, absolutely. The difference in the size of the rear pads is HUGE.

What change? Were the first few made with a smaller caliper?

 

I think it has something to do with the bleeder screw. I am not sure what other years are but on my 97; I use a 11mm wrench on the bleeder screw.

 

If I remember correctly I used an 8mm on my 00.

Guess what?

It isn't in there.
