    Hello! I found a bracket years ago that is for a Jag 1980s Salisb/Dana44 that would flip the calipers rearward and have a parking brake to the front. If I remember correctly, it was sized for a wilwood caliper. I cannot find any saved information about the bracket as far as mounting instructions. It appears to require a minor bit of machining tho. I'll post a picture of it shortly.

    Welcome to the HAMB.
    First that's a bit out of the HAMB zone, which is why it got moved.
    You might get some help here, but you might have a better chance on a Jag site or some place that deals with them a lot.For example, the T bucket forum has a guy who is adapting a Jag IRS in his build right now, and he's a sharp dude.

    It might help if you say where you are or at least where it was you got this. We have members all over the globe and if this is a regional thing, that may help ID it.

    Thanks Rod
    The only information I have been able to track down was a bookmark back to this site with a user madmike3434. I'm still digging through some stuff....

    I did a search for that member, and they have not been active since 2019 and don't have a profile page.
    Pretty scant info. They mention Canada as home.
    Here's their postings. Most seem to be in the single thread.

    This will give this another bump. Hopefully someone who has some experience with this shows up.

    I just did a search for @madmike3434 and found that bracket on a Jaguar center section. Here’s a few photos from his installation, no mention of machine work to install the brackets that he had CNC machined, they were not from Wilwood.

    Wilwood is mighty proud of that manual parking caliper, $185 ea. from Speedway or Summit, less pads. The caliper floats on the brackets, you split it to install on the bracket.

    That looks like a very neat setup. I'd guess the machining might require adjustments to the face where they bolt up so they remain in the same plane.Perhaps shimming washers. That's common on Wilwood and Jag.
    Looking for others, I found this.

    Not nearly as clean, but the forum might have other stuff for you. Not trying to push you away, but they are more involved with this stuff.
    An old thread here, which has a link to another older thread.
    https://www.jalopyjournal.com/forum/threads/jag-irs-info.607606/

    and another forum discussing e brakes and the issues.

    The T I posted is being built 20 miles away, but I've never met the guy and have no way of contacting him. Only saw his first car once at a show. He's got a youtube channel, but this new build isn't there yet.

    Mike was serious about his builds, he had grade 9 bolts made to hold the calipers. Grade 9 is 180,000 psi tensile strength material, and I think the low crown socket heads were necessary to clear the third member. A socket and ratchet wouldn’t fit but an Allen wrench would. The bolts were drilled for safety wire.
