I had a small proble with my brake slave cylinders not releasing quickly, so i stripped emm down to have a look... All looked OK but there are little machine marks left from the CNC process.
So i got a little felt polisher and some Belgom and flashed up the dremel and in no time at all the bore's were mirror polished and super slipery
When rebuilt and all bled through the brakes were 100% better.
I assume this would work well on other brakes as well
Anyone else tried this ?

Lauterbacher twin pots work fine without polishing them
