Yes, the JL8 used the 4 piston calipers but they were mounted with different brackets than the 67/68 cars. Every piece to the JL8 brake system is unique and expensive. I know of around 12-13 documented JL8 cars. The crossram is a natural fit with the JL8 since the JL8 option was really for racing purposes.

I have a friend that keeps claiming he has a JL8 car and that its a COPO 427 to boot!
I guess I'm going to have to go look now and see what he's really got. What does the original JL8 cars have thats different he's
told me before the calipers front are different from 67/68 and the mount brackets.
I guess I'll have to dig up Camaro Untold Secrets and take a look I remember pictures in detail of the whole JL8 setup.
Does anyone know of big-block JL8 cars or COPO's being built?

I thought there was a dealer in CA that had a 396 Pace Car that is claimed to have the JL8 brakes, but I don't think it has documentation. I thought the special black/gold ZL1 that GM built for taking to shows or to show what they could build had the JL8 brakes as well.

I called about an RS SS 350 convertible that sounded like it had the JL8 option. The guy said he bought it from the original owner who raced slalom with it. He had the original paperwork and pictures of the car in a newspaper from the 70's. He kept telling me it cost over $5,000 new and that it had the disk brakes on it. I was on vacation and wasn't paying attention, so by the time I got back home and realized what it was, it was already sold. The car was Frost green with black deluxe interior but had repainted orange. It had power windows, tilt, gauges, M21. I wonder who's got it now? The guy was only asking $25,000.

The orange/orange JL8 car I had in the '70s was sold to a guy from Florida. He was building a JL8 Z11. Don't know what happened to it.

I remembered another JL8 car we had in storage for awhile. It was - - paint, black custom interior, X77, seemed to always be Dusk blue. Nice car, came out of Colorado.

Re: Z/28 / JL8 question

I just bought a 69 z/28 hugger orange that has 4 wheel disc brakes on it and I am trying to find out if they are the real deal. The car only has 16,300 miles on it.

Re: Z/28 / JL8 question

This might help... found it in the archives:
SHORT JL8 four wheel disc steering arms, 1969 Z/28 Heat Treated, Shot Peened, (probably short) LH 3916237, RH-3916238

JL8 brakes use a rotor that is 1.25" thick.

The JL8 rear calipers weren't clocked to the front OR to the rear, they were almost straight up at the top. Do a search and look for some pictures

Here's a post with pictures: https://www.camaros.net/forums/showth...t=jl8+calipers

Well, they were slightly clocked so that the bleeder screw was at the highest point. Even with that they were a pig to bleed and required pressure bleeding to get all the air out.

The centers of the rear calipers were like at 11 and 1 o'clock as the pictures show in the link provided by Joe.
