98+ CAMARO “LS1” Brakes: Bigger & Better Period

[Xophertony]

wow, i can't believe i read EVERY SINGLE PAGE. i feel as though i just ran a marathon. well, after all the pages i have a question i do not think was covered, asked, but not answered. the bolts that bolt the calliper to the caliper abutment bracket (carrier). i have not seen a GMPN anywhere. can anyone help me, or point out what post# it is in so i can see where i missed it? thanks much. EDIT* figured it out. 8mm x1.25 x 28?mm with a flange hex head with green loctite applied is the way they are factory. i could not find a 28MM at the hardware store so i went with a 25, a 30 was too long. i also could not find a flanged head, so i got a washer. i spent 4$ and i have 4 extras.

[Xophertony]

well, i am having a bit of a fitment issue, i bought my brackets from Ebmiller (so i did not just hack these out myself) and they are not quite right. the bracket rubs the caliper. look:



i am wondering if i should clearance the bracket or the caliper... i could probably do a little of both. there is a casting injection mark right there that sticks out a bit i could sand down.... then i guess i will have to take a file to the bracket.

I`m thinking of doing a C5 LS1 brakes conversion on my 3rd gen Formula. But I have a question. Will they fit with Ronal 1991-92 Firehawk 17 x 9,5 wheels?
Anybody tried fitting those brakes with 1991-92 Firehawk wheels?

Thanks again for reply and sorry for offtopic.

check out this thread on the brake board: http://www.thirdgen.org/techboard/br...l-fitment.html (Brake upgrades and wheel fitment)

[J's T/A]

Here is the deal on the brakes and the Ronals.. I have them and love them but brake clearance sucks.

You can fit:
firehawk brembos if you can find the parts
1le kit
Baer sport with a 12inch rotor
Ebmillers 12 inch four piston wilwood kit
LS1 brake kit

You can't fit:
anything else, up to and including:
LS1 kit with upgraded c5 calipers
C5 brake kit
Baer kits with 13inch or larger rotors.

Hope that info helps.

holy crap, this is an AMAZING thread!! Im getting my parts from a donor car tomorrow and hope to have up some pics once Im finished. I heard someone on here talk about polishing the calipers. Anyone done this yet, and if so any pics? Im polishing mine, and Im thinking about putting some candy blue powder coat over it to really make it pop. Plus, the color almost exactly matches the color of my car!! So how bout it, any poslied LS1s?

[lock]

Wow, post still kicking. Installed fronts 3/04 thanks to Ed.. they are still rocking and no issues at all since then. Great job Ed, everyone who helped get it going... and of course thirdgen.org!

Ed, missed ya at the autofair... I was MIA in 07 though but the IROC is back on the road.

Polishing would look killer but hard to maintain. Polish with a candy coat would look killer. go for it. I went red/black powder coat on mine. Also polished up my spacers... notice the caliper reflection

[V6canvas]

Nice job on the caliper and houb, I mean mirror you have there...

This thread is great, hopfully I will have my car back on the road soon with the LS1 engine and trans to match the brakes I think the brakes might have 200 miles on them since I put them on, definatly less than 500. its been 3 and 1/2 years since they were put on, dang.....

[BlueZee28]

Ok I'm still waiting for Ebmiller to PM me back about getting some brackets for my LS1 brakes, but in the mean time, is there someone on here that has been making hubs for people? Or do you guys just do it yourself? This is one of the steps that I'm afraid to tackle myself...

[spills]

I just got done with one of mine yesterday. I took them to work and put them on the brake lathe, and just turned the rotor .002" at a time, but only 1" out from the "hub" center. Took me about an hour to do one, but I didnt want to burn up any of the bits. Most machine shops wanted anywhere from $60-$90 PER rotor! Needless to say Im glad I work at a Chevy dealer

i just orded the 2 sets i've done from here..


http://www.bigbrakeupgrade.com/

[V6canvas]

I got my whole setup from ebmiller, don't know if he still does that or not.

[spills]

Im pretty sure he still does. I had to get some random piece for my PBRs on my 9 bolt, and he had plenty of them in stock, and zinc coated! Definitely the guy to see if you're looking to reduce the amount of fab'ing on this setup you have to do yourself.

[spills]

I think Im done with my setup, only one other question I have for ya. I made my bracket out of 3/8" steel, and I guess I have the "late" style spindles, the ones with the guide bosses on the spindle are raised. I flatened those down to try to center the caliper carrier over the rotor, and from the naked eye it looks pretty good. I think to get it perfect I would have to shim it, basically the thickness of 1/2 of a M12 washer (very technical, I know ). I was looking for some around the shop today, and just about everyone I asked said that as long as it looks pretty damn straight, I shouldnt worry about it being perfectly centered. What's yalls opinion on this, do I need to shim it to get it perfect, or would just slightly off center make that big of a difference?

[spills]

Just curious, how to yall measure the distance from the rotor to the carrier when you're trying to center the carrier? Ive guesstimated that I need about 1/2 the thickness of a standard washer to get mine pretty centered. But I was just wondering how precise yall get yours. Some of the guys at the shop that as long as it's pretty close by eye, it shouldnt matter. Any advice?

[V6canvas]

I would imagine, that as long as it's pretty close, and nothing rubs, you are good to go. Sorry I can't be of more help, but I got my whole set up from Ed Miller, so I didn't really do any of the fab work on mine.

Bump for you

[spills]

bump, Im about ready to bolt up the spindle on the car, I need some final input.

I had some clearance issues that seem to make the caliper carrier sit cock-eyed, now that that's fixed, all Im worried about is just how "center" the carrier needs to be. I measured a NEW GM rotor, and I noticed that the 2 sides of the rotor are not the same thickness I dont know if I need to take that into account, or just center the carrier and go. Again, just how "centered" are we talking about here?

[spills]

whoo hooo!! I got mine finished!! all I got left is the candy red top coat on the calipers, and the new seals. I got all my clearances done finally, and all looks pretty nice. a HUGE thanks go out to all yall who've contributed to this thread, I haven't even gotten these things on the car yet and Im already getting compliments on the work. Couldn't have done it without yall!!

[spills]

I did manage to find some 10.9 M12 bolts with the wide head (dont remember the exact name) at my local Ace hardware. About $2/bolt, but worth it in my opinion. Red loctite on all bolts, and hopin for the best!

Note: You can see where I had to shim out the carrier a little. I ground a little too much off the spindle. It's not 100% centered, but it's about as close as most brakes Ive seen from the factory.

[gta324]

Anyone has a picture of the grinding that needs to be done to make it clear GTA rims without a spacer?

/N.

[spills]

I thought all that needed to be done was put some small washers on the lug studs underneath the wheel? I've got a Camaro, so I didnt really notice any of the GTA info

BTW: I forgot to post pics of the polished and candy powder coated calipers! sorry for the small res, had to take pics with my phone

Here's a link to the pre-coated calipers:

Why would you want to grind your GTA wheels? You would have to grind a lot of material (not so much depth, but all the way around the wheel) to get the right clearance. Just get the spacers, they aren't that much money and you won't have to spend hours grinding your rare/much sought after GTA wheels.

[gta324]

I was thinking of grinding on the *"brakes" if its possible, but If I go this route I'll probably end up using spacers, just curios where and how much it would hit.

It's hard to find used parts over here............

That would make more sense , I read your question quickly, guess too quickly. I don't know that I've seen anyone grind down the calipers, if you want, I can take pics of what I did (spacer).

[84ls1_transam]

Just wanted to keep the thread going. I was just wondering if anyone has the measurements for the caliper bracket to spindle bracket. I can figure it ou if know one knows. just want to fight with it less.

[spills]

There's a pic somewhere on this thread that has a scaled drawing of exactly what size it needs to be. Just print it out to scale with the scales drawn on the pic and go to town.

[84ls1_transam]

I tried to bring it up, and it said that it had been shut down. Now what? Unless I was looking at the wrong one. Any idea what page?

[spills]

hmm, ya you're right I can't pull up the page either. I found one drawing on page 3, but that's not the one I used. I think mine said "version 2.0" or something, so I would guess that it was modified. Send ebmiller88 a PM, he's the brake man around here, maybe he has it saved on his PC somewhere.

[84ls1_transam]

Thanks man.

[gta324]

Did you get the LS1 bracket drawing?

I'm also looking for it.............

/N.

[daferris]

Here is a copy and a way to print it EXACTLY the right size to use as a template.... first download from Autodesk the free program "DWG true view" the current link to the 2009 version of it is at http://usa.autodesk.com/adsk/servlet...MP=ILC-DWG-PUV
2nd download the AutoCad drawing and print it. I will post it a copy of it on our local Boy Scout site www.masontroop763.com sometime tonight look on the very bottom of the home page for the link "LS1 bracket"

Dave

[gta324]

I use Autocad at work so THX!

/N.

[RAD5]

See attached.

[Morit]

Is this the final, best bracket?
And the sizing is ok, if I give it to the machine shop thy will need nothing more besides the thickness?
How do I know If i have early or late model spindles? Which year was the change?
Also I think all holes are the same size, is that how it should be?

Ok, really new here and may be posting this in the wrong thread so feel free to direct me to the correct area.

I found this thread in a Google search while looking for info on a Ford part I am trying to sell for a local garage. Another site (a parts store I think) only gave me a chart of Ford SUVs that used the bolt to hold the tranny to the bell housing. Reading here gives me the impression that the bolt can also be used for the LS1 brake assembly. I am looking for the most correct info before I post them on EBay.

Is the N805163-S100 bolt a tranny bolt that can be used for the brakes or a brake bolt that can be used for the tranny or was it designed for both? Also, is there anywhere I can get a list of vehicles/brake assemblies/trannys that it can be used for?

Thanks in advance.

Mount the sensors in the caliper bracket the and locate an ABS module off of a 1993-1995 F-body and you'll have all the hard parts (if using a 4th gen rear). I'm sdecifering how to wire it currently, don't expect updates too soon!

Can we use these instead of maching down the third gen discs?

That bolt fits a lot of things. I just used it for a brake caliper bracket.

[Strangecars]

Hello Everyone, I just changed jobs and found out I have access to a auto cad plasma cutting system. I have used the auto cad program for cutting the caliper brackets I will be using on the LS1 brake upgrade on my El Camino. I can cut stainless steel,mild steel and aluminum in whatever thickness for LS1,C4 and the C5 caliper brackets you might need. Also anything else that has a auto cad program. I don't program the auto cad I only run the plasma machine. Contact me if you need a set. Cost would be minimal plus shipping. strangecars@yahoo.com

Sorry to piggy back on this thread but would this same approach apply to a firstgen f-body. A 67 camaro with front and rear drum brakes. Would I just need a different bracket?

So all I would need for the front is the brake calipers pads and rotors right. I can use my drum spindles and hubs correct?

What about the rear?
