this is the master cylinder and adjustable span lever, the black powder-coating was flaking off where the brake fluid was leaking out of the reservoir which was damaged, quick splash with nitromors, a blast with the brass wire cup-brush in the drill and some stainless domies out of the stock draw and it's looking good, i'm going to use a little plastic harris fluid reservoir on a carbon fibre bracket, i got a formula 3 racecar airbox off one of the girls at work who's old man works at a racing manufacturer, they were going to chuck it in the bin but i can re-cycle it, it's good quality autoclaved carbon.
