These caps are relaced by the big cap Davo mentioned. Either or. Like rocking-horse p!!!!!.
Had a master cyl. done up a few years back and the bloke managed to get a 2nd hand 1.
Every brake shop I've been to have come up zilch.
I did get 1 from the states. Cost me more in postage than part. It's in 20l drum with all of the other brake
parts. Will use it on the master cyl for the GT from Adelaide and KB.
