English Axle - R31 Disk Upgrade

Hey Guys,
I thought I'd start a little side thread from my build thread to show how I've gone about my rear diff upgrade. I'll be running the R31 disk upgrade. So I'll show where I've run the lines, brackets and other little bits added.
 
It's not complete yet however I have a quick question for those in the know. Due to the Tran X halfshafts being ever so slightly longer the disk doesn't sit neatly in the centre of the caliper. I've added a washer which has made the gap about 40%/60%. This should be fine right?

    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.

    Cheers

    Well It's all been installed. Here are some photos of the handbrake mechanism. This was the head scratching bit. I used most of the standard R31 handbrake mechanism. I had to lengthen the standard cables from the calipers to the centre bit. PM for the exact measurements if you're interested to save you some time. I'll be pulling it all out and painting the diff housing etc to finish the job. I'll post photos when I do.
     
    Cheers

    If you could send me the measurements when you get around to it. Cheers!!
    The handbrake setup all looks pretty new from the pics.. where did you source it new? Or did you clean everything up and replace/refurb items individually? 
    Conversion looks great! Nice choice on the shocks as well

    Standard r31 h/brake cables can be used without lengthening.

    It's funny how thins work out.  I am doing this conversion right at this moment too.
     
    What did you use to join the handbrake to the cable splitter dealie?  I was thinking of using the original cable and just getting a plug welded onto it.
     
    Good work, it's looks nice and neat
     
    Cheers,

    RS2000: Yes, however the length chosen will depend on your setup and clearance from other items like exhaust etc. I was going to get new lines anyway and I wanted heat sleeve put on mine near the exhaust. So I thought I'd extend a little in the process.

    There are a few other little things that need to be done to make everything work flawlessly which I'll send via PM if required.

    No worries EVO. Yes the handbrake cable from the splitter are new. The splitter I just cleaned up. Calipers are fully overhauled with new parts. Bracket is from Paul Dunston. I like, new, painted and shiney ;)

    Matt, I'll PM you :)

    The other half, of course, there is many ways to do something and achieve similar results. However you posted that you had to lengthen rear cables, this can be taken as 'its a must' when it's guite the opposite, standard cables fit perfectly. I also run r31 brakes and have 3 inch exhaust with possibly bigger muffler and it all clears nicely. Also I consider using off the shelf r31 cables a benefit.
    Good work tho cars coming along nicely.

    Any chance of some pics of it all with the 3 inch exhaust as i'm struggling to find room for mine. I have the disadvantage of 45degshocks though.
    Thanks, Shaun

    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)

    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.

    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!
