Nobody seems to want to do this.

I now have a bad brake setup on the S4 where the inner pad is pinched hard between the caliper and the disc.
Obviously I'll get that sorted but in the short term, I can take 1mm off the inner pad and things will be ok.

Anybody know who could do this for me in the edinburgh area, this week?
I started with a sheet of sandpaper but that will take me a week just to do one!

I've done loads as I had the same on the rear of the vw.
I just used a grinding disc on an angle grinder & any uneven bits soon bed in against the brake disc.
Wear a good mask tho

Cheers Chris.

I'm going to shim the calipers inwards by 0.8mm as that will sort the silly offset I've ended up with. The Calipers are around 1mm too far outboard. 0.8 is a close as i could get.
Those pads cost about 10quid per mm while the shims (hardened bearing thrust washers) are much cheaper and should do the job until I can get hold of the guys who made the brackets. Plus I'm on track on Saturday so I can't wait for them. M12 bolts with a 25.5mm O/D washer will be plenty of area to spread the load and only a couple of mm less contact diameter than the brackets themselves.

The angle grinder occurred to me but I'd be guaranteed to leave the pads looking like a ploughed field, and give myself lung lurgy to boot. These XP12s aren't even legal on the continent, they're so nasty.
But that will be my last resort, as I'm not missing SIDC again, plus there's another on the following Thursday.

If you know anyone who works in a machine shop, you could get them to skim a bit off for you in a milling machine, it would be neat and equal across the face of the pad.
Just an idea..

Just watch out for the dust! Nasty stuff.

Belt or orbital sander with a dust mask on. Very Happy
