I've got a new dc pots mod quick release that you could swap with that one :daumenhoch:
-
you sure it can be changed? the actual quick release is rivetted on....or do you mean the little bolt on part? :daumenhoch:
-
old qr is cut off and the potts mod qr fitted
the adjuster is different for a front as well rob
both the above parts are available at porkchops
alternatively just cut off the qr and fit a cable guide. take off the adjuster and set it up as you would an fs880 caliper
you will need a longer spindle as well
get a bulldog front for 9.99 and swop all the parts maybe :-\

grind off the rivit and press the new one in. I can do it for you if you like .. i use a friends industrial press :daumenhoch:
i have a spare one of these .. http://porkchopbmx.com/Dia-Compe-replacement-quick-release-for-front-brake-1008304.htm
then you just need one of these .. http://porkchopbmx.com/Dia-Compe-Brake-Adjuster-FRONT-883QLADJ.htm

The spindle is fine as it's going on a set of LG's so the rear spindle is just the right length.
Wildon, PM me with details and how much you want for the work and if no one wants a trade then i will take you up on your very kind offer :daumenhoch:

You don't need to drill, cut or fook anything up to convert it to a front:

New one from Porkchop

Unbolt the micro adjuster and bolt on a one from Porkchop then feed the cable through the QR mech up to the newly fitted adjuster which has a cable pinch olt on it :daumenhoch:
OR you could just take off the micro adjuster and put the pinch bolt there and lose the ability to adjust cable tension ;)

So Marty, you're saying i don't need a new QR just a new adjuster bolt from Porky?
???
-
the quick releases are different front and rear. how would the cable slide through it? you'd have to leave the bolt loose. it'd be a bodge job and the nut would work loose and fall off
-
thats what id say as well terry
the qr on the front has like a cable guide fitted
-
i'm sure the QR is diferent Marty, i will check out the front on my other street beat later :daumenhoch:

I've done this before and the solution is really easy. Remove the anchor bolt that (secures the cable) from the QR and get a pear shaped ferrule and put that in the hole were the bolt used to go. (this holds the outer cable in place like a proper front Nippon QR does - then the inner cabe is clamped by the new Porkchop QR) It was a while ago when i did mine so I can't remember if the ferrule need a little fettling with a file so it fits snugly in the QR assembly but it definitely does the job.
Ferrule
