I've just bought some brake levers and fitted them to my gilera runner. I am not sure what master cylinders I have or if they are all the same on the runners, with just different front calipers, Heng tong etc They are operating the brake but have freeplay/movement in them. I have found a video online to show the same pronblem. This is what mine are like! Does anyone know how to correct or source the right master cylinders without the same problem occuring! ( as my levers are nice ones!! ) Thanks Rick.
I think the master cylinders are diff, as just tries the lever on a scrap yard grimica master cylinder on it fits lovely, shame there not for a runner!!!
