have converted to cooper s disc's on a dual circuit master cyl and have been told that this will work, but when trying to bleed the line nothing is happening and the pedal isnt going its full travel

help would be great
is there a different master cyl for disc or can i modify mine or is there something simple im doing wrong
have wasted 4 hours already

I have just changed to alloy 4pot 7.5" calipers from 8.4 standard calipers, and the pedal is no where near desirable.
It pulls up fine, but the pedal is crappy.

After changing masters three times (dual circuit) , and also the proportioning valve (due to locking rears before - even with the 5/8 wheel cylinders) the pedal still doesn't come up like it did with the 8.4s.


Have you changed your rear wheel cylinders to 5/8 (assuming it doesn't have them already)

no the only thing i have changed is the front disc's from the drum its a 78 clubby
do i have to change anything else

1275LS's used dual circuit MC's with disks, as did late drum braked minis... so they're the same, some Nb racers use dual circuit MC's too... it should work just fine

just check you have the calipers the right way up - the bleeder goes at the top, otherwise you get a nice big air bubble in the top of them that'll never bleed out
