Jag rear brake Wilwood conversion help

cobrarkc,

I have the same rear vented brake setup as ERA Chas. It uses the Jag calipers with spacers and the Jag e-brakes. It is not a completely simple install, but works really really well on the street and on the track. It has over 25,000 miles on it and I'm on my second set of rear pads. Maybe the third, I forget, track use does put extra stress on them

Here's what it looked like when it was new:

I also use the Wilwood manual proportioning valve. The knob sticks through the floor at drivers right to allow on-the-track adjustment. I've found once I adjusted it to prevent rear lockup, I didn't need to do it again.

Dunno if Mike still makes this setup. If so, it's expensive but worth it in my view.

I used the same setup as Tom and Chas...very nice setup. If I remember correctly, the toughest part was modifying the brass forks to deal with the wider caliper.

John,
How do you modify the brass forks?

I don't know if Wilwood makes a kit for it but it would require a steel adapter to mate the W'wood bolt holes to the Girling locations. Then there's always the correct rotor type/width to source. I don't know for sure but it may require shortening the half-shafts.

I know it's no help but I think mine came from CWI with the correct forks. It's the brass 'plate' with safety wire seen here. Fit perfectly across the bridge and I just wired them on. They can be fabricated but the fork ends taper and bend into the e-brake arm's holes so it ain't easy.

I'd doubt you'd find any major performance difference between Wilwoods and these-possibly except in track-only use. And John has subjected his to that sort of use. Mine has seen less of that but once I got the F/R bias correct, they were perfect for 120MPH stops on the strip. Also, pad selection is a major contributor that helps performance. I'd try to find these if possible if you want a significant upgrade.

I also remember that someone made a Wilwood kit that put the calipers at the rear of the rotor but when I was researching mine, I rejected that because it put the calipers right against the ERA gas tank and bleeding and pad changes were impossible. Sorry don't know who made those.

I had an additional piece of brass, braised into place to make up the difference for the wider rotor on the original style Girling calipers.
