Took me a while to work out how to connect the grease gun but once it was on it worked like magic; I didn't think there would be enough force to push out the piston and the pad together but pop; out the came. Brilliant; how did you come up with that idea?
Bryanj:
Back in the 70's trying everything in the workshop to get one out, you just have to be careful with the thread, original idea was to screw a grease nipple into the hole but at that time couldnt get one the right thread and found that the steel pipe fitted just enough
Laverdaroo:
The modern grease guns should come with an end that you can take out and turn round to fit the different sized nipple’s…….snigger.
Just a standard grease gun for doing the ones on a digger etc.
I tried it thinking there’s enough pressure to re tighten the tracks on a 25 tonne slew so a piston shouldn’t be too much trouble as mentioned and proven.
I did mine after employing the process on an old Ducati 748/853 I had some years ago After doing it, a pal rang me and suggested trying it, typical but you’d be surprised what you can shift using this process if you can get suitable purchase.

I had some time to work on the bike today and rebuilt the front brake. I have a new master cylinder assembly, new top, middle and lower brake hose/pipe. New piston, seal and bleed nipple. I cleaned the caliper parts and hose union (brake light switch assembly) with brake and clutch cleaner and made sure it had plenty of time to dry. New brake pads too. I filled the system through the bleed nipple. There is still some air in the system but no leaks and brake seems to be working ok. However, the brake fluid looks dirty already. You can’t see through the fluid in the master cylinder reservoir. I don’t understand where the dirt has come from; maybe I should have flushed out the new master cylinder assembly? I’m assuming this isn’t normal; should I flush out the system and start again?
