my xvs had a( bodged ) rear disc setup when i bought it

due to the old setup not working very well (the pedal pulled a cable that went to the back of the bike that pulled a linkage(that flexed sideways) an moved the master cylinder arm

i decided to fit a master cylinder from a yamaha wr i mounted it through the engine mount

as the pedal is bolted directly to the linkage it will work alot better

heres a pic to explain

the problem i have now is the master cylinder is smaller than the one desined to work with the rear caliper

the old one had number 14 on it

the one i m using now says 1/2

so i guesss this wont push enough fluid through?

so i should change the rear caliper to match the master cylinder

but this is the mount the attaches the original brake to the swing arm

an this is the caliper an bracket i need to use to match the master cylinder

not sure if it will be possible to modify it so it will fit to the bracket above?

there's only 1mm difference so the rear pedal will travel a bit further, but you should still have a rear brake.

have you tried it with this set-up yet or are you assuming there is a problem?

i havent tried it yet the old master cylinder had 14 embossed on it (i assume this means 14mm

the new one says 1/2 i assume this means half inch (approx 13mm)

i noticed the old master cylinder is quite abit longer an if i mount in the new location the pedal would hit the ground (hence using a shorter one)

so i should be able to use the new master cylinder(1/2) with the old caliper intended to work on 14 master cylinder

i need to get a braided hose made upto use them but if it doesnt work chances are the hose will be the wrong angle if i fit a different caliper

Dont panic Mr Manwairing, Yamaha used 1/2" calipers for europe and 14 mm for the states on many bikes with the same calipers on the bikes, you will never notice the difference

thanks mervin

the caliper an swing are are from a sachs xtc not that it really matters

i ll get my hose made up at weeked an hopefully it will work

better get the right Hose
