    Doing Up Old Mags

    Morning everyone (or is it night time over there )


    I've picked up an old set of HFX Mags from my brother for dirt cheap. They used to belong to a mate of mine and he tells me there a 2000 model, he's a mechanic so they actually feel pretty dam good for there age. So I'm thinking, New levers, New Lines, New Pads, a fresh bleed and some new bushings to get rid of the sloppy lever, they'll be good as gold

    I'm abit of a forum junkie, and every now and again, no matter which forums it's on, I see someone who has done this to their mags and absolutely swears by it, I must say it's got me alittle interested

    Im going to go with Goodridge lines, the only think I have to verify is if they have a G1 or G2 caliper. I had a squiz on the Hayes site and I'm pretty sure there G1, is there any physical differance between the G1/G2 I can see to confirm ??

    Considering the G2 came along in 03' I'm pretty sure there G1, but would just like to confirm.

    Also, has anyone else done something like this to their Mags? I'd love to hear about it !!

    G2 caliper has a cutout in the back. That's the most obvious difference.

    This is a G2 caliper

    And this is a G1

    Glad I can help. Those Mags are terrific brakes. If the MC in mine hadn't gone out, I probably would've stuck with them.

    I agree with Will, the Mags rock! I have them as standard issue on my '02 Jekyll 3000 and was thinking of upgrading the levers to carbon and maybe doing the lines. Do the lines make a big difference to feel? and do you have any ideas on the best levers, eNVy make some nice alloy ones as well.
