Source for JB9 brake adapters?
#2
Are you wanting to add '88+ 12"(JL9) or maybe '88+ 13"(J55) or maybe C5 to an earlier car? CTS-V stuff or ...............
Now for a GM truck JB9 would be a hydro-boost I believe. Does that interest you?

Maybe you need to clarify what you're attempting to accomplish. The JB9 reference is only I thought just a "light weight" usually mentioned when discussing B and W bodied GM cars.

If you are looking to improve braking performance, I would recommend going to a performance pad. The cost will be far less and there are some very good pads for the early C4's Hawk makes some good pads as does CarboTech.

The stock '85 front rotors are 11.5" in diameter. Why would you want to "upgrade" to a JL9 12" rotor? The front rotors for the '88 and later J55 brake option is 13" in diameter as is the C5 front rotors. But either of those would require special brackets to mount the caliper properly. And the 13" rotors would require 17" diameter wheels.

As you know, a 12" rotor with a dual piston caliper and larger pad will out perform a 11.5 rotor and single piston caliper and smaller pad of the same compound!
The JL9 fits in an 16"wheel (which i have 12 of)
I've read various posts that mention such an adapter and Im trying to identify it and where to get it . It would be a good option for my purposes!
so if anyone knows of them,it would be a big help!
Thanks

I have an 84 and the brakes I'm sure were great back in 1984, but i found them seriously lacking on the freeway when everyone else has a modern brake system with abs.
I did the C5 brake conversion, it's much better now.
There is also a bias spring for the rear brakes, i hear it will improve a stock brake system as they really underpowered the rear brakes.
Cost is about $20 shipped, search the forum, there should be a few references to the site (DRM maybe).

I've looked for a "sales guide" link in the past and actually never stumbled upon it. There's a variety of documents but I've never seen a "sales guide" that was all encompassing. I just glanced quickly again and didn't see but maybe I've overlooked it AGAIN!!

It's there - let me know if you find it - OK ??????

Yes - it's been found and that's the way I thought I remembered the conversion to "dual piston" from early "single piston" design.

Look here in the C4 Parts For Sale section. Looks like it's a complete set and has been on sale for a few months.
