After collecting parts and info for the better part of 2 years I finally made the move and started my Legend caliper swap on my 2000 Gsr.

My problem now is that my passenger side seems to be grinding the front part of the caliper and the rotor together. It was making a rhythmic slight ( not grinding but rubbing ) sound as i was driving and I bent the dust shield back, torqued everything down, bled the brakes and i was able to reduce the sound but not eliminate it. Has anyone else had issues with getting this setup to work for them? Here's a list of my specific setup


Legend Gs front calipers w/ stock hardware, positioned where the bleeders are upsidedown

Fastbrakes.com 11" HD rotors for the Legend/NSX swap

Fastbrakes.com Legend GS caliper brackets machined to fit the integra.

Gsr Blade rims.

To using the correct directionality for the dual-piston caliper.

The rotor is actually contacting the caliper? Post a picture.

 

yeah we need a picture. did fastbrakes mill your brackets for you?
and did their "HD" rotors have centering rings? (I persoanlly use Legend GS rotors and rings.)

I didn't know those actually cleared the blade wheels.

The front of the caliper cannot touch the rotor, as there is a big *** pad in the way. Its possible the brackets were milled wrong. Check the edge of your rotor for contact.

Good call. That would be obvious by watching the rotor rotate in the caliper with the wheel on.

 

I can't really tell where between the rotor and the caliper there is contact but i drove down the street and my caliper was smoking.

I went back home, took the rotor off, took off the dust shield completely, took off the hub centric ring, sanded down the hub a bit to get rid of the rust so the ring could fit better and tried again. This time a lot less of a rubbing sound but still some traces of metal on metal rubbing together somewhere.

The calipers do clear the blades. Contact with the rims is not a problem.

I tried checking where the contact is coming from but I can't tell.

Fastbrakes did mill the bracket for me. Both sides. Only the passenger side is having issues.

Oh, and i think this is a product of me not having bled the rear brakes ( and letting all the fluid drain out overnight on accident ) but the brakes REALLY pull to the left when i stop.

 

I'm frustrated, i need help. I'm almost ready to just give up and do a simple accord v6 caliper upgrade. something that is hub centric and does not have to be bled updsidedown.

Does anyone know what year accord v6 calipers i have to buy to be the same as the ITR? What other stuff do i need?

Disassemble and look for scrape marks. Are you sure that the caliper is moving on the slide pins?

I tried looking for scrape marks on the caliper but I couldn't find any and the thing is all black.

The slide pins seem to be working fine.

 

Spin the wheel by hand with the car raised while watching and listening.

 

can we get a picture of the centering ring? Also, if the whole system bled dry, did you do the proper bleeding order and bench bleed the MC before? If the system has any air in it, its possible one or more of your brakes are working much harder. Regarding that front brake, take the caliper off and check it out. You may have one of the retainer clips that fell off and is rubbing, or the pad spring is [freak]ed up.

 

i have done the same swap had to use washers to space out the caliper from the rotor i used the washers in between the blots that mount the caliper bracket

I tried that but nothing makes that much of a sound, I'm talking about a rubbing that is only noticeable when i'm driving +20

I double checked the retainer clips and although it hasn't fallen off, i believe it is rubbing somehow. What do you mean by the pad spring? You talking about the clip at the bottom of the caliper?

 

I've been working on this project for 3 days, I'm fed up. Dogginator, i know you've done the accord v6 upgrade. Are those rotors you use hub centric, and is there any caliper bracket grinding required? I think I'm gonna do that or go back to stock.

 

As a man who has had the Accord V6, ITR, Legend GS and NSX brakes on his car, I would doublecheck the milling job. However if this is a high speed thing, I'm wondering if your lug nuts aren't torqued properly, or your pads aren't bedded in. Are you running shims?

 

Is this rubbing constant or a swish-swish-swish?

I machined the mating surface of the caliper bracket by 2mm with a mill. The 92-96 Prelude VTEC rotors are hub centric with the correct 64mm center bore.

 

Not to nit pick, but I've always machined them 3.2mm, as the ITR hubs relative to the 4 bolt hubs are 2.5mm more in protrusion from the knuckle.

They are centered. I used the total rotor height for the 2mm (47mm for ITR and 92-96 Prelude VTEC vs. 45mm for the non ITR DC2).

Kinda like the swish swish thing.

So those rotors work with the accord v6 or itr calipers? What years of accord v6 will work?

 

pics coming soon

Check your affected rotor for runout (wobble). Debris or corrosion on the hub face can cause this. Also check your wheel bearing because it could cause this type of issue.

If I recall correctly, my calipers are from a 2000 Accord V6.

 

ok pics. Notice the line. It's very slight and can not really be felt by hand.

ok, to answer some PM questions:

The ring was hard to get on the hub. I had to hammer it in and i was still left with about a fingernail sized gap from the back of hub and the ring but i didn't think much of it cause I figured the lug nuts would push it in. Diameter wise, i think the ring is actually about .01 mm too tight, which is why i have had a hard time getting it over the hub.

I found out what's happening, the rotor is partially hitting the caliper bracket. At a certain point it does make contact with it. If i back out the caliper bracket bolts just a bit it centers it better. I'm going to get some washers and see if that helps and allows me to clear the rim. I'll then bleed the abs the right way to see if everything is fixed.

This is still a big pain in my *** and I really wish i had gone with a hub centric ITR upgrade....if only i had been warned.

Just used a washer in between the caliper bracket and the car and it seems to space it out well enough to where there is no contact.

Still, i don't like this upgrade due to the rotor not being hub centric. The upsidedown bleeders i can deal with though.

Plus side, I haven't even bled the system correctly yet ( just the front calipers and with the car off ) and i can tell a huge difference. I'm sure it'll be just as good if i decide to get the accord calipers, minus the hub and bleeder issues.

 

sounds like a pain in the *** for sure.

 

Ok so I'm movin on from this project to the ITR one since that seems easier to deal with, with the hub centric rotors and the bleeders being upright. I just wanted to ask you guys to clarify which hub centric rotors I should be getting.

Fastbrakes.com has the older Prelude 4x100 rotors for sale and the ITR rotors redrilled. Are ITR rotors hub centric to the non-ITR Integras?
