Has anyone here used rear disk brakes from a 2002 Camaro on a 69? I thought I read something about this swap a while back and bought a complete 02 disk brake rear end and am trying to figure out how to proceed. Thanks for any info or links.

The popular choice is the '93-'97 Camaro rear disc's because the way the e-brake connects, it fits into the 1st gen like it was made for the car. The '98-'02 will require a lot of fabrication and I don't know about finding brackets to mount them to the axles. Someone has to have done the deed, hopefully they will type up!

From what I remember, all caliper brackets (where thy mount to the tubes) are all the same. But I could be wrong.

One comment about the ebrakes on the 93-97 camaro disks... It is proving a little challenging to locate the correct bracketry to terminate the aftermarket rear ebrake cables to the calipers. The "loaded" calipers from most auto parts outlets do not include these parts and GM has discontinued the replacement part numbers (along with the caliper mounting brackets).

I am sure that given enough time and patience you could readily find the necessary parts. The issue that I mention above is chronicaled much more technically in other posts in this forum. Just wanted to give you a heads up that it is not quite a slamdunk if you are sourcing the parts individually.

FWIW - I have done a quick cost calculation and it would have been worth it to me to specify a kit from one of the multiple big disk brake suppliers that support this website than to piece my own together....:o

Maybe you didn't understand that I "bought a complete 02 disk brake rear end" and will not be piecing it together.

Assume you plan to transfer the brakes to a '69 rear end and not retrofit the '02 rear into the '69. You might be able to reuse the axle mounts and bolt it all up but I don't know what the '02 axle flanges look like. Give the folks a call at www.touring-classics.com I am sure Noel will help if he can, tell him I said to say hello...

I don't know what the '02 Camaro shock setup is like, but I doubt they are "staggered" like the 69 Camaro is, which could cause problems for you. The 69 has one shock ahead of the axle and one behind, and disc conversions "usually" require two passenger side calipers and caliper mount brackets to clear the staggered shocks, and to keep the bleeders pointing up.

02s aren't staggered and a lot of aftermarket kits require removing the calipers to bleed. Since it wouldn't be needed often, I wouldn't have a problem doing that if there are no dynamic issues having the calipers staggered.

Hopefully www.pro-touring.com will be back up soon. They have an excellent disc brake section, and those guys have tried just about everything.

I plan to do this swap, have a complete 98 rear. I plan to move the shock, and use the setup as is. From what I have read, the shock is the only issue, and you need a 3/16 spacer, some have even cut out the drum backing plate and used it. Like mentioned before, pro-touring has a lot of info on their site about the swap.

Looked around www.touring-classics.com and didn't find anything about OEM rear disc brakes or swaps/interchange which is what I'm interested in...just their 12" system which I don't care anything about. If someone could just point me to where I can find out if the caliper brackets will bolt up to my axle tubes so I don't have to tear my car apart to find out, I would really appreciate it.

My advice was to call them, they did the reasearch when establishing their kit which is a Vette C4 and Camaro 93-97 transplant. Noel sells what he sells but will share info and help if he can, I know they looked into the swap you are doing before deciding what they would offer and support.

Try TSM, ECI and Mosers and see if you can't pull up the housing end bolt pattern info b/c I will bet that this is a bolt-on.

pdq67 and my homemade "pdqCBB" 13" front and 11.75" rear disc brake set-ups!

I've been around the horn on this crap, but not this new a parts...

I did this swap on a '67 (non-staggered) and it was pretty easy. The '98 - 02 disc backing plates bolt right up to the '67-69 rear housing. On a '69, you will need to move your shocks inboard, or use two of the same side off the '98-02 setup. The calipers can be mounted up or down on the backing plates so there should be no problem getting the bleeder pointed up.

You might look at some of the Blazer/Jimmy rear discs. They are similar, but staggered versions exist and the PB cable mount is integral with the backing plate making the swap easier.

Since I already have this, the Blazer brakes are out. I pulled the parts off the rear end today (02 Camaro) and discovered the backing plates will bolt up but in order to get the E brake cables oriented where the levers move forward when applied (making fabricating a mechanism easier) the calipers would mount to the rear of the axles on both sides instead of to the front on the 02. This is fine except the drivers side shock mounts to the rear of the axle and I understand this causes interference with the caliper. If there really is a way to remount that shock to the front without causing any unseen issues, I'd like to find out how and what's involved. Except for the shock, this would be pretty straightforward. Then I was thinking the only other way to do it would be to somehow obtain another drivers side caliper and mount it to the front of the axle while the other side would mount to the rear. Have no idea if that would cause problems. If it would work, I could also just stagger the ones I have and remove the drivers side to bleed???? MAN...if that left shock wasn't in the way...

You could build something like this pretty easily, but as I see it there's a potential exhaust interference issue.

PS No problem at all with one caliper ahead of and one behind the axle.

Calipers don't cost that much. You could always get another driver side caliper from Autozone or the like and use your passenger as an exchange. The calipers are symetric and don't care which side backing plate they are mounted on. I saw where one person mounted the backing plate upside down, but this requires moving the holes a little in your one backing plate. There would be no problem having one cable pull forward and one pull back or one pull from the top and the other from the bottom.

Hmmm, thinking, thinking, thinking...

One thing I need to find out before I take my very enjoyable to drive car out of service for who knows how long is, will my 15x7" ralley wheels clear the calipers? The rotors are 12".

That's a big no, you won't get a 12" brake behind your rallys...

Man....I didn't need to hear that. I just refurbished all of them with new rings and caps (at great expense I might add) plus, I really like them. Any ideas? What will clear, 11s? And from what vehicle. I knew it couldn't keep going this well...

16" wheels for 12" rotors and 13" rotors take 17" wheels.

Do a search b/c all this is here somewhere.

16" wheels for 12" rotors and 13" rotors take 17" wheels.
pdq67

13" don't fit in all 17" wheels. The whole reason I'm running the LS1 brakes is that I couldn't get 13s to fit in my 17" wheels.

The LS1 rears are set back pretty far and the caliper has a low profile, but I seriously doubt it will fit. You can check it easy enough by taking one of your assemblies and laying it inside a wheel.

I found a couple of links on rear disc upgrades from both the 93-97 and the 98. The second link, scroll down a little past half way.

I got 12.12" behind my 15" Crager SS wheels (rear wheels) The front are 10.75" but I could have gone bigger!

I am using the good old fashion 79 trans am caliper/11" rotors on my 8.5 nova 10 bolt with 15X8 4.5"bs ralleys with no clearance issues. ebrakes work also.

Big difference compared to factory rallys. I tried to mount a 15x7 FW wheel on my '96 SS and there was no way it would fit. Your wilwoods calipers are a lot smaller than LS1 brakes as well...

Individual rim & caliper choice matters. I have 12" rotors on my 77Z with stock calipers & 5-spoke Z rims. But the same setup with SSBC calipers does not fit (by all reports). Other 15 rims do fit. So it's not always a hard & fast rule. Buyer beware, measure twice, yadda yadda yadda....

That's what I did. I also found out the 97 discs are a little smaller, 11 7/16". I may try them but I still have the shock issue to deal with. I don't like the idea of bolting/welding a brace and rigging shocks like that. I'm leaning towards staggered calipers if I can get the wheel clearance needed.

Which front disc system do you have? I'll just throw this out there - if you have factory 1969 single piston calipers in the front, the 4th (LT1 or LS1) Camaro rears are a poor and possibly dangerous match due to the drastically different caliper piston bore sizes, fluid volume requirements and line pressure requirements.

Hmmm...first I've heard of that. Is this just your opinion?

Early 4th end rear brakes should fit even 15" wheels, I believe they are carry over from the late 3rd gens. I might be wrong.

Hmmm...first I've heard of that. Is this just your opinion?

I guess it's my opinion, but it's based on the research I did when I swapped to big brakes. Here's what I believe to be true in a nutshell:

The stock front single piston calipers have a very large piston bore.

The bigger the caliper piston area the more fluid volume is required to move the piston, but less line pressure is required to provide adequate clamping force. Large(ish) MC bores are required to move that much fluid, and the larger the MC bore, the less line pressure will be delivered for a given amount of leg muscle on the pedal.

Kinda the reverse is true for smaller caliper pistons, like those that you're considering. They require more line pressure to provide adequate clamping force, but less fluid volume, and hence, a smaller bore MC to provide the proper pressure.

So if you mix the old large single piston fronts with the new small piston rears, you have brakes that really require two distincly different MC bores. The fronts will want a large MC bore, and the rears will want a small MC bore. If you were to use a small bore MC with this setup, you pedal would likely go to the floor because the fluid capacity of the MC couldn't keep up with the fluid volume requirements of the big bore front calipers. If you were to use a large bore MC you wouldn't create enough line pressure to effectively operate the rear brakes.

That's kind of a simplified version of how I understand things. There are guys on here way smarter than me who could explain it better. Here is a link to one such guy, CarlC, who really knows his stuff.

My 96RS came with factory 4 wheel disc brakes. My front and rear calipers are both single piston. The fronts are heavy cast iron and the rears are aluminum. Does the stock 69 camaro caliper have a larger piston than the 4th gen? Either way, you should change your master if your putting on rear disc brakes.
