I haven't been able to find an answer on this after searching extensively, and not wanting to deal with the melee that is the Integra forum, and since this is racing related I figured I'd post here.

After running a janky brake setup last year on our endurance race car with DX civic uprights/Legend calipers/DC rotors, having to grind down the new pads quite a bit to not hit the rotor hat, and having caliper/rotor rubbing issues, we decided to just run all DA parts.

That said, we realized that Hawk doesn't make many options for DA brake pads. We really like Hawk HT-10 pads and they aren't available.

My question: Will DC pads fit on DA calipers/brackets? I have been able to determine with some certainty that DA rotors and calipers are the same as the DC alternatives, the only difference being the caliper bracket.

If the pads won't fit, can we run a DC caliper bracket? Will there be any downsides or limitations to doing that?

Thanks for the help.

 

I'm 99% sure those dc calipers will fit.

what rotor were you using that the pad hit the hat? 10.3? Just put 11.1" rotors on and you should be fine.

 

did you mean pads? I don't think you really answered my question...

 

Hawk does not list a DTC60 pad part number for the 94+ integra.
They do list a DTC60 part number or the DA integra.

I have been using the "DA" pad for 2+ years in my oem 01 GSR calipers with no issues.

 

I asked you a question to better answer your question. An 11" rotor will fix your ' having to grind the pads' issue and give you a larger rotor.

 

The DA pads are a slightly shorter and thicker than the DC pads. If you are looking to stick with the DA brake system, I would recommnd the DTC-60 pad if you like the HT-10. Hope this helps!

wow, that is awesome info. Thank you very much!

I'm thinking the DC pads might fit. as the important length (distance between ears) is the same, and I'm guessing the calipers will accomodate the increased height, and thickness certainly shouldn't be a problem. Although the ear dimensions look different... Is there any way you can get measurements on the ear width for each?

I think I can get my hands on some DC pads to try out in the DA calipers. I'll post with my results.

DTC-60 might be a tad aggressive for us, I dont think our temps will be high enough to get into the effective range of that pad.

 

I appreciate the advice but that would still be a frankenstein setup. The rotor would have to have the correct backspacing, we also had the caliper brackets machined for our old setup and I can foresee complications that could lead to problems on-track we're trying to avoid.

 

Are you running this car in any particular class? Would just switching out to the complete DC Integra setup be an option? Would be all factory, no modifications and much better pad choice. Just throwing out ideas here..

 

I ran that set up for about 10 years problem free.
I don't know what class u run in, but more brake for an enduro car would be nice.

Oh, and as far as rotor offset, there is a spacer you can now run behind the rotor.

 

My primary question with that is, are there any complications running DC calipers/pads on a DA knuckle?

 

So here is what I've been able to find out with some certainty: Experienced opinions have told me that the caliper bodies are the same, as well as the bracket on both the DA and DC. It seems as though the only difference is the caliper bracket *Hardware*. Whether or not the DC hardware is actually needed to run DC pads, I am not sure yet. I'll post an update tonight or tomorrow on this.

 

Depending on how thick the spacer is, that is another part that could be potential issue (if it gets damaged, bent, making sure it is proper thickness to get even pad wear and life, etc) and if its too thick you lose your hubcentric centering of the wheels when you mount them.

Like I said, anytime you run a frankenstein setup there are *always* complications. Just not worth it to us. Reliable, cohesive Integra brakes all around on our light EF chassis with good race pads will be plenty. Its looking like we'll be able to run DC brakes with only a $5 switch of bracket hardware.

 

OK, so we verified for sure that EK civic calipers are, in fact different than DC integra, contrary to what i've been told/heard for years. The pistons are smaller and the brake pads are bigger. That is what I was going to use to compare to DA calipers, but obviously that didn't work out.

I'm trying to get my hands on a set of DC calipers. But perhaps someone on here has a set and could take some pictures? Particularly of the bracket and bracket springs/hardware to hold the pad in place, and maybe some measurements like the piston diameter, the size of the canals where the brake pad ears sit, etc.

 

Any update on this s1ngle? I'm interested in running the HT-10 pads on my DA setup as well.

I've used DC pads on my DA racecar just fine.

 

Last year I was all gung-ho, in love with the DTC-60's until they bit during a qual session while I was in a heated championship battle. The DTC-60's delaminated and the pad came clean off the backing plate. I still have it and can take pictures. Pad was only 20% worn if that. This cost me a session and could have cost me a race and championship.

Right up until they delaminated I loved them but once bitten twice shy. So now I'm trying a couple other compounds (both oldies) that are new to me until I find my "miracle" pad.

Actually I have a miracle pad called the Cobalt XR1/XR2... My last 2 times doing business with them however made me swear not to give them another dime... that verdict is always up for revision however.

 

The real miracles are made by Carbotech.

I will never stop recommending Carbotech Brakes. I have specifically run the Hawk, Cobalt and Carbotech and speak first hand.

My experience. The Hawk HT-10 pads came as freebies, spares with my track car, a 2000 Si, 2150 lbs empty, lasted about 400 miles and totally disintegrated to metal on track. No excuse for that.

Colbat XR2 were a huge upgrade, but they devour rotors and leave a highly corrosive film of dust that turns orange like rust all over everything.

Carbotech XP10 are by far superior to both, two sets lasting more than a full season of hard track time. They are incredible stable, very strong under abuse, never fade right down to the final 16th of an inch. Very little dust, like an oem street pad. Also, they are silent.

I wonder if those recommending Hawk have ever used Carbotech. Maybe, maybe not, probably don't know what they are missing. I've used all three.

 

That's very, very odd. Are you certain you didn't have a set of Hawk Blues? The reason I ask is that I've used those, and when they're cold they sound like cheese graters scraping the rotor. The dust that comes off them is corrosive, attaches itself to wheels/painted surfaces and rusts.

I've also used Cobalt XR2s. There was barely any dust from them, and the dust was very light colored. What dust there was came off easily. The rotors also had very little identifiable wear after beating on them for 4 hours of track time. I did have a set glaze, but I think that was due to a different brake issue that basically forced the front brakes to provide ALL of the stopping power for the car.

 

Yeah, I still have the two piece black plastic box/case the Cobalt XR2 shipped in. Nice pencil holder. Two other guys have had the same experience. We were all running ITR calipers and pads. I liked the way the XR2 worked, it was the dust and cracked rotors that ended their use for me. What you describe for the Hawk Blue is exactly the issue with the XR2 as I experienced.

So did you settle on running Cobalt XR2 pads a few more times or migrate to something you found even better? What vehicle are they one?

 

I went back to the Raybestos ST-43 I was using before. I've tried the ST-41 and preferred the extremely hard initial bite those have but I had problems getting them to bed properly unless it was scorching hot outside. Got weird pad deposits and vibrations. I *think* the problem was that I couldn't keep them hot enough to properly bond the transfer film.
In hindsight, I did forget to block the brake ducts, which probably would've helped bedding the 41s.

This was running on my ITA-prepped '92 Integra, stock size brake hardware so it sees some pretty high peak brake temperatures under race conditions.
