i may just be venting but does anyone have any little secrets to seat new brake lines? replaced the single chamber w/ dual chamber master and where i ran new lines just don't seem to be able to get them to seal! maybe just getting weak as well as "feeble minded"! about to put a cheat pipe on my flare wrenches!
Remove the lines and make sure that there are no metal filing on the flair. Tighten the shit out of them
