Shimano Caliper Piston Removal Method - RS785 - 2 Piece

Removal of ceramic pistons from Shimano calipers.
As long as you're able to lock some air pressure into these calipers you should be able to push out the pistons. If try to push one out without something between the pistons it could be that the ceramic pistons flies out and hits the opposite ceramic pistons which can lead to them cracking.

I just refurbed my 785 calipers so this was really useful, thankyou.

No problem. Did you use the Ali Express seals?

@@Chambers36TheEnter Hiya, no. I got what appear to be the correct material seals from an eBay seller.

[@Chambers36TheEnter]

@@squicker Cool, good that Shimano stuff has finally gotten the spares.

What is the Machine you used for this ?

[@Chambers36TheEnter]

It's just a battery operated tyre/tire inflator. The one I have is made by vonhaus.
