Hi Guys,
Neat looking install there. I've got the same setup with r31 calipers, English axle and Paul's fitting kit.
However, I have a bit of an issue with the caliper not clamping the discs evenly. From the picture you can see the outer pad is only sweeping the outer half of the disc. The inner pad appears fine and is sweeping evenly. It's the same case both on the divers side and passenger side brakes. 
Paul, when we chatted a few months back I since had the calipers removed, dismantled and inspected. The calipers are definately not siezed, so I'm at a bit of a loss..... 
Has anyone had a similar issue or could I have done something wrong with the install?  Would appreciate any suggestions!  Cheers guys.
(P.S. sorry to go a bit off topic)

Let them bed in...

If I recall the pads have a little knob on them to locate them on the piston. This is supposed to slot into the piston cut-out. If the piston isn't rotated and aligned correctly then the knob won't be seated properly within the cut-out and you'll end up with this problem.

Here's a pic of how the slot should be on the calipers.
 
Cheers,
 
Matt
 

Thanks for the suggestions guys, much appreciated.
I just had a quick look at my pistons and they are correctly aligned with the pad locator.  Sorry for the poor pics.  One photo is looking down the central gap on top of the caliper where you can see the position of the piston slot, the other is looking up on the opposite side.  Hard to show in the pics but the piston and pad look to be sitting correctly as you have described, which might confirm why at least the inner pads are sweepiing evenly, just doesnt explain why the outer pads are not sweeping evenly....  A while back i also marked the outer side of the disc with texta, the texta marks are still there on the inner half of the disc, so the pads are not even touching the inner part of the discs even under braking.  Any other thoughts?  Cheers!

Seized slides for the caliper ???
Or something blocking the caliper from moving (sliding) correctly ???

Shocking  photos,
however if it is all assembled correctly and slide pins are free and smooth,  just let them bed in. it may take some time before it looks 'right'.
Had it been the inner rotor side and not outer you probably wouldn't even know. 
Cheers

Thanks guys. I will double check that the slide pins still move freely and there's nothing blocking the caliper, then continue down the bedding in path.... It does seem quite a large tolerance though if it is just the case of more bedding in required.
Don't get me wrong RS2000, I'm not at all concerned about the look, but concerned about what braking performance I might be losing and also what my engineer might say when I try to get certification for all my mods.
The other half - sorry to hijack your thread!

Update: The diff and Caliper conversion is fully fitted and working perfectly. The new handbrake cables are a dream. I highly recommend this as a project for anyone wanting rear disk brakes. I'll post some photos of the diff removed and fully painted in a month or so...
 
In the mean time I've found out quite a bit about this R31 rear upgrade. Apart from the classic ford guys liking this option, Clubman and Datsun owners love this mod too. Paul Dunstan here on the forum makes excellent bracket kits to fit these. See here http://www.classic-ford.org/cfp/tm.aspx?m=21020.
However I've found that Datsport offers full spec upgrades for their cars. See here http://www.datsport.com/brake-rear-conversions.html
It seems they also offer fully overhauled and panted R31 Calipers ready to fit for $230. Quite a bargain IMHO considering how much it cost to overhaul and paint mine. See here http://www.datsport.com/brake-rear-R31-caliper-DBP2690.html
Might as well steal them off the Dat boys! haha
 
Escortinadriver: Yup, I'll get to that photo when I can....

Being a floating calliper it should be fine.
I have some extra gold plated 2.5mm spacers if it will help centre the rotor better? Might look nicer than washers too :-)
Free + postage if suitable.

 Can I take you up on these mate?
