The pump on my Ur started to leak from the top cap (brake circuit) - tried a
reseal kit, no joy, tried another type of o-ring, still no joy. Second-hand
pump (from an early RR Ur-q) lasted 6 months before it started to leak from
the same place. Exchange pump from Audi fitted last weekend - no leaks so
far.....
