Evo 8-10 Brembo Calipers DSM Conversion (for 1g too)

[bradikus7]

I read somewhere that the factory Rx7 5 spoke alloy wheels will fit and those are 16's right? So we could run slicks on them? Plus they are like 13lbs each. Anyone able to confirm the fitment?

 

[907dsm]

Yes that is true... IIRC you would have to run a 20mm spacer or at least that's what the Evo guys do. Search on Evom I'm sure you will find more information.

Finished the swap today and thought I had enough clearance in between the caliper and rotor (wasn't exactly centered for some reason but I thought it would be fine) but I drove it and they are definitely hitting each other. It is offset to the outside of the car, meaning the outside of the caliper and rotor are hitting. I am thinking about just getting 1/16" spacer to add on to the spacer that came with the kit..thoughts? I will be taking a caliper with me to the hardware store to verify tolerances.

You mean it is offset to the inside, if the outer part of the caliper and rotor are touching. If the caliper was offset in the outer section, the inboard part of the caliper would drag.

Did you make sure to grind the casting smooth on the knuckle where the adapter bracket mounts? Excess casting material here will not let the bracket sit as it should.

 

[Dyesuperman]

Just to update the above post. I had all of the casting grinded off but for some reason mine just needed more taken off. Took off the bracket and grinded some more off and problem was solved!

Anyone have really bad brake squeal issues after doing the swap? Mine have howled like a banshee ever since and I can't see to figure out why. Nate (9!'clipseDOHC) came out to San Diego for a few days and him and I drove around in my DSM, he suggested the squeal could be because the pads aren't flush on the rotor. I checked and it seems pad wear is even however the loud squeal is still there, I've narrowed it down to just the front driverside though.

Any ideas? Thanks.

I have the same issue, not sure what to make of it. I'm using pads with shims (Posi Quiet) when I have some free time this weekend, I'll take everything apart and see what I can find.

My pads won't/aren't flush with the rotor (grinded a little too much off the bottom ear so it sits a little bit crooked) and they don't make any noise. You may check to make sure the rotor is centered in the caliper. Before I centered mine up every time I would turn the rotor would rub against the caliper and squeal obnoxiously.

 

[gofer]

I'm going to look into it more this weekend as well, its annoying because its so loud under light braking.

 

[Dyesuperman]

Just want to show my steps to the install. To my knowledge nobody has posted up pictures of how much needs to be grinded/ what needs to be grinded when they are clocked upwards, So here they are. Also had my calipers machined instead of grinding them then I painted the machined part red.

I'm in the middle if doing my install also. I said "screw it" as far grinding the caliper, and will have them machined also.

Btw, sick. The red wheels look great.

 

[arrowhead]

Anyone using wilwood for these set up I have a set see if maybe I could use them, if not I am leaning towards the brembos.

PLEASE contact me if using the wilwood set up.

thanks

Gimmie gimmie caliper brackets, finally after 5 years am resurrecting my money pit

 

[bradikus7]

I am not done with the install but I wanted to share a few pictures. I had my uncle do the machining for me. He did an amazing job IMO. My setup is slightly different than most because I went with the Evo X setup. I also am clocking them up. When it comes down to it, there is less material removed than you think.

We used that casting line as the depth. Worked out perfectly.

So i have finished up my swap with the jam knuckles and have a few questions. Like the person a few posts above me i too have low pedal pressure squeal like no other. It is highly annoying and i don't know whats causing it. Also my pedal seems to be much softer, i bled the brakes at least 10 times each myself before taking to les schwab to have them do it when I was getting my alignment. They gave the car back to me today and said it was all done with no issues. Feels like a slightly softer pedal than my old 2 pot brake system. Any suggestions.

Did you upgrade to ss lines? I went ahead and got ss lines when I did mine and pedal pressure is maybe a little soft but definitely nothing to worry about/get annoying. It feels pretty good on mine...did you bleed in the correct order as well?

 

[bradikus7]

People have had a soft pedal issue. You can upgrade to a 3G Eclipse master cylinder and it should solve this problem. Do some research though because I am unsure of the exact model you would need it from.

 

[bsbllfit7]

Ya i upgraded to SS lines and everything. I had the feeling the brake pedal was supposed to be more firm with this upgrade. Much like the brake lines of a Volkswagen Jetta for anyone who has drove one (for those who have not you barely need to tap them for them to engage). I was hoping for that feeling and didn't just want to have the cool look that came along with these brakes. I was trying to search for information on if i needed to upgrade my MC but couldn't find any. Anyone wanna point me in the right direction.

Also when i have the car off the pedal gets extremely firm if i pump it. Almost to the point where you can't push it anymore because it is so firm. Could this have something to do with the ABS or Brake Booster? If the MC was going i would think it would have the same issue when the car is off.

 

[gofer]

The soft pedal you're feeling is because the brake master cylinder size, you'll have to upgrade it to something similar to the Evo's. Some have tried swapping in a Evo BMC with no luck because the fitment, below are a few pictures that Matt Laplante took of his Evo BMC install. What makes it even worse for me, since my car still has the GS-T BMC on it, is that its even SMALLER than the AWD's.
The sizes are as follows:

2g GS-T - 15/16" (0.937")
2g GSX - 1"
Evo - 17/16" (1.062")​

Beau Brown (EclipseGSX1736) found that an easy solution to this is picking up a 300zx TT BMC which is the same 17/16" as the Evo's. Pair it, with the larger 3g GT brake booster and your pedal feel will improve.

'91 300zx TT 1.06" MBC
'03 Eclipse GT 9.75" Brake Booster​

You'll have to bend your own hardlines but your mushy brake pedal will disappear.

Here are the shots of the fitment issues with the Evo BMC.

Hey Corey what about the 3g master cylinder? Will that have the same fitment issues?

 

[bsbllfit7]

So is this a common problem that all of us are having after installing these bigger brakes? They brake just fine but I definitely like the feel of that more form pedal than what I have now. Just wanting to see what other brembo dsm converters are going through with their pedals.

 

[gofer]

Yes but the problem DSMers have ran into running the 3g BMC is that the reservoir is too big and hits the body of the car.
I'm fighting the same issues as everyone else has with this brake upgrade, without changing the BMC the pedal is going to feel like a sponge.

I'm still trying to find the source of the squeak though, its only the front driver side so at least I know where to start looking.

 

[bsbllfit7]

Mmkay as long as I'm not alone on this spongy pedal then that makes me feel better. I am gonna swap the rear pads out this weekend and put shims on the back. Hopefully that will get rid of my noise. Is there anyway of machining the mc? I've never tore into one so I'm unsure as to if it would be possible.

 

[gofer]

Machining the MC, possible? I'm sure, anything can be fabricated to work but by no means is it going to be cost effective or easy to do. If you don't like the pedal feel or brake response then spend the $200 extra bucks for the 300z BMC and 3g BB. The only fab work you have to do is the brake hardlines which is a simple DIY'er mod, they sell that stuff at any car parts store and you can rent the bender.

The hardlines you'll need a 10mm x 1.0mm.

 

[Dyesuperman]

Yes but it isn't the 17/16" (1.062") bore size that the Evo's is, its 1" like the GSX BMC. I'm fighting the same issues as everyone else has with this brake upgrade, without changing the BMC the pedal is going to feel like a sponge.

I'm still trying to find the source of the squeak though, its only the front driver side so at least I know where to start looking.

You know right after you posted earlier about your brakes making noise, my driver front started making some noise too. Only when cruising though, not when braking. It's weird because I made sure everything was installed in a way to prevent any brake noise and I still have it.
