DTR brake seals

[Tristan.]

Ugh, ordered some seals for my completely seized rear calliper, and the seller had front ones for half the yamaha price so I ordered front ones too

removed the old rear seals which disintegrated and the front ones (lost the fluid seal, dust seal is here but unusable) when the new seals turned up they are the wrong sizes, the seller sent two o the same sets, the DT brake pistons are very different sizes, one of the oil seals sort of fits the front piston, but with ~ .5mm slack, when it's in the calliper there's no slack, but I would of thought it would be a tight fit without the calliper pressing it in.

Anyway he's asked me to get him the measurements but the only old seal I have is the front dust, so I'm really really hoping someones recently stripped DT calipers or has autodata and feels especially helpful

it's an '88
