Maintenance & Technical > KX500 Original
is there a front brake master cylinder upgrade?
alexander-vmann:
i noticed that my 93 k5 is leaking at the front master cylinder (the brake thingy at the handelbars) and was wondering if a kx250f or kx450f master cylinder would fit on the hose, or if even a newer hose would fit on the caliper?

you can try a rebuild kit, some guys have good luck with them....
if you buy a new hose/line, get a stainless steel.
I threw on a 2012 CRF450 master on my 250, made a huge difference...then about a month after, I backed it up with one of these...

the slightest touch on the lever will lift the rear wheel off the ground now.

sweet :-D but will any master fit my hydraulic hose? or just 450 master?

I've only done the Honda swap....but as far as I know, the Jap bikes all use basically the same banjo bolts...and you should be able to use just about any master you want.
I don't know if KTM or any of the other non Jap bikes use the same banjo bolt...maybe someone else can answer that.

Alexander,
Check if the leak is just coming from around the Banjo Bolt (the bolt that goes thru the brake line to that thingy). It could simply be just the Banjo Bolt Washers, a very simple & cheap fix.
