Reply to "Brake Master Cylinder question"

An interesting consideration when flaring brake lines...
I needed to customize my lines when I went to a new master cylinder and booster. I bought a double flaring tool as suggested by my auto parts professional. I kept having leaks at the flares. I called Dennis at Pantera Performance and he told me that the original lines are prone to cracking when you double flare them. He suggested a Rigid single flaring tool from Lowes/Home Depot. It worked. Now I can flare anything on the block! If you're using all new lines, then the double flare is best, but if you're adapting old lines, I'd go single flare.
Also, watch out for a combination of European "bubble" flares on your junction blocks and proportioning valve, with metric or american flares at the master cylinder. A "real" auto parts store should have the Euro bubble flared tubing if you need it.
Mooso.
