Magura TPA disassembly/replacement?

[foz]

Can anyone help with some instructions on taking apart and rebuilding magura TPA adjusters? I think they're the earlier style, with the adjuster in the lever blade.

There doesn't seem to be anything in the manual or in the RB archive, and I don't want to force them or do it wrong for fear of breaking them (if they're not already :facepalm

thanks!

and another question... on HS33 brakes, can I use either a shroud nut and olive OR a barbed fitting?

just unscrew them iirc, then they just come apart.

Quite obvious or at least I didn't have to think about it, think it may have been lever bolt off fist to take the lever off.

does this help any

thanks. just unscrewing them they seem to come to a point where they don't want to unscrew anymore, i?m not sure if turning them more will break them?

In the manual there doesn't seem to be a detailed explanation of the tpa assembly, or how to replace it

Just remembered some fool put some stuff in the archive after he bought a set early this year

can't think who that was

that was the first place I checked this morning... nothing there on the TPA that I could find though

I stopped by the LBS this afternoon - he has shimano hoses complete with the barbed fittings, olives and shroud nuts (turns out I need to use all 3 of those bits :facepalm: ) for little more than a tenner, so a fair bit cheaper than the magura equivalent and a lot easier to get hold of.

Any idea if the threads on magura and shimano shroud nuts are the same? or if I could just use the shimano barbs and olives, and my existing magura shrouds?

Also, I see magura sell rim brake and disc brake specific hoses - what's the difference? Can I use a (shimano) disc brake hose on magura rim brakes?

As you can probably tell, I have no idea at all about hydraulic brakes

thanks!

I think you need to use shroud nut and olive where they go into the pistons but but barb is OK where it goes into lever body. At least on hs11s

I also know little and have spent a few hours tonight bleeding a hs11 without getting it to move at all!

Re:

You can pull the pistons out to clean and grease them.

It was all new to me a dew months back. I think Shimano are a larger fitting.
Tartybikes have info on their parts and trials forums to.
