: 1968/69 Rear Disc Brake???

Has anyone found a rear disc brake kit that mounts on 68/69 staggered shock that uses a left and a right caliper? I don't want the 2 left calipers and other hokey things like that. Must have parking brake.

Any kit that puts one caliper ahead of the axle and one behind is likely to have identical calipers in order to keep the bleeder screw on top.

If you want to keep both calipers on the same side of the axle, Wilwood Dynalites are pretty slim and would probably clear the shock. They also make a kit for staggered shocks, but likely use identical calipers. http://www.summitracing.com/parts/WIL-140-9315-DR/Application/?prefilter=1

LS1 brakes have been used as a R and a L as well, but it's not a "kit"

To tell you the truth the LS1 link w/photos is not very clear, I can't tell which is which side exactly. The question then is will the stock, L & R LS1 set clear staggered shocks? There's plenty for sale as "kits" I just haven't determined if they actually clear staggered shocks in basically stock form.
Wilwood is not my taste, nice looking over priced imports.

This is the only picture he posted showing the shock and the caliper on the same side of the axle. He states that there is 1/4" of clearance between the shock and caliper. I assume this to be with new pads. As the outer pad wears that distance will decrease. There is a little room to fudge the shock closer to the spring also, if you modify the lower shock mount plate, but you might consider that to be hokey as well. I thought about trying it this way, but my rear hard lines were set up for one in front/one in back so I used 2 lefts.

Thanks, 1/4" is close, if you let the pads wear down to where you shouldn't they could touch. I wonder if there is a difference with mult leaf springs as compared to the mono.

Not sure on that. Check your PM

The Wilwood calipers are symetrical, they all have 4 bleeder valves, so they work fine in any orientation. Note these are fixed, not floating calipers, with 4 pistons not 2. They don't bind up, they don't stick.

Wilwood is an AMERICAN Company, that has made racing brakes in America LONG before Baer and others started bundling red painted autozone spare parts to enthusiasts. They are competitively priced.

I don't mind low cost Asian imports but $1000+ for Wilwood imports is too much. Plus since they generally put their name all over the calipers I would also have to overspend on a front kit as well.

Joe, are you saying CPP has a kit that uses left/right for 68/69? If so, which kit? I have only seen ones from them that use 2 left side calipers.

i have them on my 69> the drivers caliper is forward and the passangers is rearward opposite of the staggered shock locations>

got them with the CPP big brake kit from matts classic bowties camaros. give him a call

My bad, it uses 2 right side calipers. I would like to find a kit that uses a LEFT and a RIGHT caliper. I'm rapidly begining to think it doesn't exist. I was hoping someone has made a bolt on bracket kit that uses this configuration. Maybe it's impossible.

Now you got me confused. both bleed from the top, both E-brake cables enter the bottom and they are opposite of the staggered shock locations on each side. How can they be the same?

The calipers have to be two of the same side to keep the bleed screw up and have them on opposite sides of the axle tube. It's not bad, I guess, I was just hoping some company has figured out a way to keep both on the rearward side on a staggered shock application, without relocating the shocks. I've been searching but nothing found yet, so I thought i'd ask if anyone else has found such a kit.

There is no room on the drivers side with the rear shock crossing over the spring.

you could relocate the shocks inward and get them both rearward with the shocks staggered. other than that, you would have to place both shocks forward.

How did the factory do the JL8 brakes in '69? Were the calipers staggered opposite the shocks or were they both on the same side of the axle? Also - what did the JL8 use for an e-brake? Anybody know?

VERY GOOD QUESTION
I was thinking that yesterday also. I wish I knew how it was done-love to own an original.

OK - A little research shows the JL8 caliper at close to the 12:00 position. Not sure where the bleeder is. I think the e-brake was drum in hat.

To bleed that you would turn one end upward to bleed then re-install. If it used a drum in hat it could have been a modifed Corvette set up.

Put your own kit together utilizing parts from a 79 4 wheel disc trans am. That has the correct staggered shock orientation like the 68/69 and it will work with the 10-bolt and also has a parking brake you can get the calipers rebuilt from your local autoparts store and axle lines/brackets from right stuff if you are using stock 69 front disc setup then the rears will be a good match. good luck and work safe!
