Has anyone tried to do a mod to put rear disc brakes on these ol Bonnies?

I had seen an ol Olds or Buick in the J/Y with rear discs, and thought that might be a cool thing to do on a Bonnie, as long as you can keep the ABS working to boot....

no one has ever done it, you need to find a rear hub that accomidates for disc brakes and fits the bonneville (which is nearly impossible)

look into the pontiac 6000 STE, they are the only cars that used the same abs system as us and have rear discs.

Hmm... an STE might be hard to find in the J/Y... but its something that I'm interested in... could be an interesting adventure... if anyone has any ideas or tips, please let me know...

Nah, there were 3 in the JY by me a while back. All are gone now though.

I installed Riviera rear discs on my 87 Lesabre. I had to fabricate my own caliper bracket and my parking brake isn't installed yet, however. It is possible though with enough ingenuity.

If someone wants to do brake transplanting, find out if H bodies can add F body calipers and rotors like the W body guys can. I may dig into that this summer myself..

there is a guy on 3800Pro that added F body cailpers to his 91 Park Ave....

Keep in mind as you look into this that you need to maintain the front/rear bias. If the rears are not doing enough work the fronts will be over worked and have fade issues, if the rears do too much you may find yourself facing the wrong way at a bad time.

Pat do you have A link I couldn't find it and I am VERY interested.
