Hi, I have a bit of a problem on my front brake for my cbr 125, one of my pistons is not moving atall there is no pressure in my leaver and it seamed like there is no break fluid getting through to the piston but I can see the fluid passing through as the other piston is out, Can any one help? hope I have explained my problem well enough.

Yeah one piston has come out of the caliper and the other does not move (can't get it out) ? Also there seems to be a problem with the break fluid getting through?

if one piston is out of the caliper exposing the hole you will need to put it back in and bleed the caliper


then once bled up you will need something in the caliper to stop the pistons popping out again while you pump the lever to free the other piston

:stupid:

I usually use a large allen key laid in the disk slot on the caliper......that stops the pistons coming out completely......so when the free piston hits that it can't come out any further.....and the other piston can then move when you pull the brake lever......as long as you have some fluid in the brake system...... :wink:
