Ok here is my dilemma
Baer Calipers
Earls banjo fitting 3/8 or 10mm
Copper and alloy crush washers, no mixing just
M10x1.0 banjo bolts
3/4 leak under pressure, granted slightly but leaks..... eat paint
Only legit suggestion I have is add thread sealer "ARP" to the bolts and retighten using new crush washers.
Has anyone else encountered this ?
