Piston Removing.

No-one has any pics or vids.

Not many people need to do this.

Actually, I never knew you could get the piston out of the lever, I thought it was part of the brake itself.

I know you can get the seals and the plunger out though.

Why do you keep coming in here if your not going to be helpful dude. Dont get me wrong the topic starter isn't helping himself with his literary skills, however its fairly obvious which part he is trying to get from the inside of the lever. The bit you call the plunger is what i would call the piston as well!? So can you offer him any help at all, or will i have to do it?

Topic starter - take everything off the lever (this includes lever blades, hoses, and anything else).

Rest the lever body on a hard surface and get a small allan key that will fit through one of the holes in the hose end of the lever body.

You will notice that at the end of the threads which hold the hoses in there is a small hole - this is the hole i was talking about above - push your small allan key through one of these holes, do it gently as you do not want to damage the spring.

Once you feel the resistance of a hard surface you are on the back of the piston. Now put as much pressure as is required to force the piston out. I had to do mine just recently and it was quite difficult to push out.

Once you have forced the piston out, give it a clean, clean out the inside of the lever as well as the spring.

Now a little lube on the seal / piston will hopefully allow a smoother running of the lever.

After you have lubed the seal replace the spring, then the piston (ensure its the right way round) the piston might need a tough push back into the lever body!

re-fit the lever blade and without re-bleeding, check that lever springs nicely back into place when compressed. (if not, you will need a new spring i think available from any DIY shoppy, in which case repeat the above, and replace the spring with a new one before yuo re-fit).

Re-bleed the brake and see if you still have problems with air / leaking. (if your brake isnt leaking at the piston, my assumption is that your bleeding it wrong) If you do have problems with leaking then im afraid your easier to buy a new magura lever rather than try and source a piston.

You either have a working brake or not at this point.

If its working - be happy - go ride - and learn to research your topic before posting and clearly write the problem.

If its not working - be pro-active - go to the wanted / for sale section and make a topic / find a lever and purchase - and learn to research your topic before posting and clearly write a problem.

Hope that has helped a little bitty :)
