I'm planning on upgrading my 95 integra gsr brakes and I was wondering what are the benefits of having EP3/DC5 brake calipers over the ITR brake calipers? They both have 10.2in rear discs, so I would assume that the calipers should be about the same size, am I right?

 

they are the same caliper in the rear. but the bleeder is in the wrong spot on the ep/rsx calipers. they bolt on the same, but when you are bleeding, you need to remove the whole caliper and flip it around. its much easier in the end to just use the itr calipers.

 

thanks batboy for the reply! that's what i thought, i guess i'll go with the itr rear caliper. also should i use the itr caliper bracket?

 

ITR calipers can mount on either bracket. Calipers are the same size. But good luck finding those ITR calipers because they are rare and when you find them they cost alot more than EP3/RSX calipers usually because the owners know what they are worth. Use 2002-03 EP3 rear rotors too

 

itr calipers are not terribly difficult. You can buy them new/reman from a dealer for about $150 each, whereas a set of ep3/rsx rears will cost roughly $140 for the pair from a salvage yard.

I've used both calipers in my rear setup (I've also had rear 99-00si rear calipers, so done it all). If you use the rsx/ep3 rears, you have to flip the calipers, so the right goes on the left, and left goes on the right. You ahve to do this because the caliper body will hit a flange on the rear trailing arm and not swing into position. You will also have to grind off a lip on the brake shield for caliper clearance. You may also have to fight with your brake lines to get them to clear properly at the caliper. This also forces your bleeder screw to point down. This isn't a big deal unless you have to bleed the brakes often like on a track car, then it gets annoying.

The itr caliper is the better way to go. Makes life simpler...

As for the bracket, you want the bracket that goes with the caliper. The reason for this is because the brake pad is dictated by the bracket *NOT* the caliper. If you use the stock gsr 9.5" rotor bracket, then you must use the smaller gsr/si pad as well. if you use the larger ep3/rsx/itr bracket, then you can use the much larger rear brake pad.

Here is a pic of the difference in brake pads. Shows a gsr/si rear pad along with an rsx/ep3/itr/prelude rear pad :




This pic shows the flange/lip that must be cut off on the dust shield. This is the rear drivers side. 2 bolt hole locations are for caliper mounting bracket :

 

Only thing it did to me was point the bleeder down. There was no machining, forcing the lines or anything. To deal with the 26 dollars i paid for both EP3 calipers and brackets at a salvage yard here like i did on half off day, I'll deal with having to bleed it once in years by taking the caliper and lifting it up. I didnt mind doing it and if it ever needs to be done again, I wont mind. Its not hard (for me that is) but if you can get the ITRs go at it.

If you need the brackets (cause some people wont separate the calipers from the brackets) let me know

 

Out of curiosity, what car do you have? I did this on a 98ex using 99-00si rear trailing arms.

 

2 different ones. A 93 Del Sol Si and a 92 Civic Dx with rear drums converted to discs using the Scarebird rear disc conversion.

 

question.. can I use the ep3/rsx bracket with the gsr caliper and pads? all i want to do is use a bigger rotor and i dont want the bleeder screw facing down... any info would be great
