    I'm having trouble with a brake line at the proportioning valve on the front crossmember. I'm converting my rear D60 to disk brakes, and I'm changing to a disk/disk unit from Inline tube that was discussed on here recently. I've got four of the five lines switched over to the new valve without a hitch. But for the live of me I can't get the fitting on the line on the pass. side of the valve loose. I've tried soaking with penetrating spray, heat, cold, bent two wrenches and a pair of pliers in the process - nada. Any ideas how to get the bugger loose?

    I suppose I have to cut the line, get a new fitting, and flare the line. I know brake lines are double-flare - where's the best place to get the flare tools? The line itself appears to be in good shape - should I just replace the whole thing? If so, does anybody make these lines in ready-to-go shape? Thanks for the help, michael

    I assume you are using a flare wrench? If not, then yes you should go buy one now.
    I would not use heat on the brake line fittings. PB Blaster and a 9/16{" flare wrench (with maybe some taps from a heavy hammer) ought to do it.

    I have used a small pipe wrench before after the fitting got rounded off using a flare fitting wrench. If the rest of the line is in good shape you could just cut off a bit of it and re-flare it. You should be able to pick up a double flare kit at any auto parts store for under $20.
