    Straight discs again!

    My buddy Tony and I went up to Pumabuild in Birmingham yesterday to get my brake discs skimmed. They have a very cool machine which will do the skimming while the discs are still in place on the car, thus making them perfect for my specific (dodgy) hubs

    I was a bit worried that the vibration I was getting was being caused by something else, but with the DTI attached it was pretty clear the discs really were about as straight as a £9 note.

    Some pics...


    The 'brake lathe'


    How the disc looks like to begin with


    That's after 2 passes with the lathe - they were pretty shagged to say the least


    Finished article - better than new (in theory!)

    There's a small video here of the machine doing its thing, and some more pics here.

    Cost was £100 plus a tank of fuel, which is about the same as a new set of discs for me, but the discs would have taken 4 weeks from America so...

    Anyway, good service from Pumabuild even if the Brummy accents sometimes needed a translator Well worth having done if your discs are expensive (or a long way away..) and you have cooked them!

    Looking good, how much does it actually take off the disc?

    in his case, enough to remove the warp, it could be as little as a tenth of a mm,

    what are the discs and whats the car ?
    are they by any chance floating discs ?

    Yeh it was just enough to flatten the discs again, only a few thousandths of an inch.

    They are Willwood rotors and bells on my CRX, which looks a bit like this...



    The trouble I had apparently was running too hard a pad. I'd changed to DS3000 compound pads for Silverstone but the discs are only 280mm and they just couldn't cope with the increased heat from the extra friction the pads were creating. So it's back to the DS2500s again and hopefully the discs will last a bit longer

    DS2500's are pretty cool - but you can see where the break force comes from - it ends up all over your wheels

    Got DS2500's on my Cally, like Martin @ Reyland said to me, pads are cheaper than disks to stick to what I got instead of going harder...


    so to speak...
