I´m worry about improving the stopping power of my 69`Camaro with original disc brakes.
I bought two aftermarket calibers for the original setup, which I could use but david pozzi think that they could flex.
I own a complete brake setup from a 92`Corvette. Does anybody know, if I can put these brakes on the Camaro (with some minor modifications) ?
The car has a two piece setup for the discs so I can use the front hub (right word ?) and the Vette discs.
For the calibers I think about using the Vette brackets with an adapter to the Camaro`spindle.
I want to use the Corvette 17" rims so caliber/rim clearence will be no question.
Tips for this setup ?
Realistic plan ?

Markus,

Have you been following my 13" Vette rotors conversion on the first gen's that I am playing with? If not, I'm making a flat plate steel caliper bracket ta mount the big single piston truck type caliper to our cars using my drum brake hubs.

I don't know if you can use the Vette calipers if you make a homemade bracket along the lines of mine. I say this because I don't know how much clearance there is between the newer Vette caliper guide bolts solid attachment point on the bracket and the caliper slide point.

In other words, there has to be enough room between the rotors back face and the spindle mount bolt bosses to allow installing the flat plate bracket plus allow the caliper to slide on the guide bolts a little bit.

My setup won't allow using a 3/8" bracket, just the 5/16" (I think). It's that tight, unless you "s-curve" the bracket like was done on the stock 1969 and up single piston bracket. And that gets hard to do in a hurry.

But, hey, I will be glad ta help if wanted. pdq67

I apolojize, Markus because I forgot we had chatted earlier and you said that you had a very hard time getting parts in Europe.

E-mail me your full name and address and I will mail you a rough cardboard bracket template so you will see what I'm talking about along with a couple a pages telling my plan. No charge!! pdq67

[davidpozzi]

what aftermarket calipers do you have?

The late vette parts would be good if you can fit them on.
I would use your old caliper brackets as a base and weld something to them to adapt to the late Corvette caliper.
Wheel clearance will be worse with the late vatte parts because they use wheels with more negative offset.
But if you use late style wheels it should work.

Markus, do you have the 12" standard Corvette brakes or the heavy duty 13" brakes that use the two piston aluminum PBR calipers?
I don't know about the 12" system, but the 13" system is basically the same thing Baer offers as their "track" system. There is a caliper "cradle" bracket that straddles the rotor and holds the pads in place. This cradle bracket has two "ears" on the bottom that are threaded metric-14-2.0, and you can fabricate a bracket that will attach to these two ears on one side and then bolt to the spindle on the other side.

I gave up on trying to make my own bracket because they would have to be somewhat bent/curved to fit. I found out that Baer sells their brackets separately for about $100 ea. To me, that's worth not having the headache of trying to make my own. I still will come out ahead price wise over buying the entire kit.

I almost forgot to metion that I am using the hubs from a drum brake Camaro and I had to turn down the hubs to reduce the diameter enough for the rotors to fit over them properly. I also might have to modify the new brackets in some way because they were made to be used with the machined aluminum hubs that Baer makes and I doubt they are dimensionally identical to the hubs I'm using.

Markus,

It might be possible to take Bret's info. and my bracket template and come up with a bracket like David mentioned when he said add metal to it so it could be moved out, or at least use the template to spot the distance needed to move the reworked bracket out. Just food for thought. pdq67

I'm trying to do the same conversion useing '94 vette 12" brakes. I have both a drum and a disc brake settup for my 69 camaro and am going to experiment to see what works best- I'll post when i know something new

[Protour69]

I'm using the same C4 front brake package on my 69 Project. Just had to chuck the drum brake hub in a lathe and take a little off the OD (outside of the studs) until the 94 Vette Rotor slid on. There was two brake options available for the C4, the 12" Standard and the 13" J55 option. In fact the 13" option is the same rotor and caliper that BAER sells you in their track kit. One thing to note though, is that the 13" option will not allow you to use 17" rallies due to the caliper interference. (I chose the 12" package to be able to run 15" Torque Thrust D's too.) I made a caliper adapter from 1/4" thick steel plate based on a template I got from John Wilson who did the same swap on his 67 Z28. Make sure you use the drum brake knuckle too, because the mounting pads are level and allow you to run the factory caliper brackets with minimal shimming.

Protour69,
I can hear pdq67 panting right now!
Have you got any photos of your swap?
I'd be happy to post them on my web page with my CBB Cheap Big Brakes info.

Protour69, I'd be interested in that template if you could somehow get a copy to me or put me in touch with John Wilson. Do the 12" brakes use a different caliper and bracket than the 13" brakes?? Do you think it would be possible to adapt your bracket to the 13" brakes? I have disc spindles now but it would be nothing to change that. Glad to hear someone else has accomplished this!

Protour69,

David's right, I'm not panting (laughing alot, though) but really would like ta get a copy of the caliper bracket template you are talking about that John Wilson made so I can compare it to mine for the 13" rotor and big single piston truck caliper.

Hopefully, we can make one for the cheap big truck single piston caliper and another for guys that have the bucks and want ta use the Vette caliper. Then if wanted for either the 12" or the 13" rotor. (A total of four homemade brackets). pdq67

The way I see it is that either spindle can be used by removing about 3/16" off the top bolt boss on the drum spindle or by adding a 15/32" thick shim at the top boss on the disc spindle.

Thats great! you have already done this to your camaro! How do you like it ? any probs? what kind of master cylinder did you use? I hope to have my car back in one peace for Woodward this year.....will I see you there?

[pdq67]

Teetoe,
I just e-mailed John and asked if he would like to make a template swap with me. Hope to hear from him shortly. Will post any answer. pdq67

[Protour69]

My 69 is at my Father's Garage in Central Ohio, and like Radio Joe I plan to have it finished for Woodward this year. The car is still in pieces at this point, but the brakes are bolted on and are mechanically proven, if not hydraulically yet.
The bracket that I made will work for both the 12" and 13" conversion, if the proper Corvette bracket and caliper are used. (ie. the 12" (JL9)caliper and bracket with the 12" rotor, and the 13" (J55) caliper and bracket with the 13" rotor)
I plan on using a 96 F-car booster and master cylinder, so that I won't have to use a prop. valve. (Also using 96 F-car rear discs on the 12 bolt and the Vette front calipers are the same diameter piston as the late F-car.) I do have a Wilwood adjustable prop valve I'm installing just to provide some adjustability.
pdq67 is right about the knuckles, either one will work with slight modification and/or shimming, but the drum one was a little quicker for me due to the short amounts of time I actually get to work on the thing! (Sad to have your baby 4 hours away!)
I will try and get some digital pictures of the install this weekend and send them to David for posting.
