Have fun with the brakelines
Those crush washers are 1 time use only, no matter if they are steel or copper. The minute they are cranked down, thats it. If you have to break that fitting loose for any reason , they need to be repalced. Thus why they sell them in 10 packs
I have fought with my brake system for the past week or so, and every time I look away
something else is leaking. Be careful of chromed fittings, as they leak like a #$%*. I had to sand off the chrome in order to get a good seal. GOODRIDGE line of products BLOWS, as all of their parts are junk, poor build quality, etc.
If I could do it again, (which I might) I would go with standard black line, with reg. fittings from the autoparts store.
