... in the centre of the disc? Im running 16v calipers with modified sliders, and basically the rest of the disc gets a good pounding by the pads except for about 1cm in the centre. The sliders were modified by a mate of mine and I dont think the bolt section at the top which was reduced was done quite flat? Could this be causing it??
Im going to try renewing the disc when I get chance. Do you think the sliders could make this kinda problem?
One of the reasons why I didn't machine down my sliders!!! Brakes are a vital piece of kit and VW made them to exacting tolerances!! Get some proper 280mm Calipers from a Seat and be done with it.
If it`s the sliders it`d be the top or bottom part of the disk, not the middle.. Best bet is to get some new slider pins modified on a lathe the get them true, but the thread into the caliper should have trued the ones you have up. Or get the propper calipers as Dayspring said. I`d go for either pads or disks as well, check them with a straight edge and feeler gauges to be sure.
Yeah i think im going to get some reconditioned calipers when i get chance, renew the discs and pads, and get my arse to a decent lathe. Its going to be an expensive winter!! [:^(]
if the caliper was on the "slightly drunk" then the pads would wear accordingly - not leave a centre mark *i take it your referring to the centre of the braking surface (wear the pad touches the disc)and not the inner edge of the disc i.e. where the hub is ??*
Definitely the caliper isn`t true then, if it`s not running on the inside edge of the braking surface (not the centre/middle of the braking surface).
