Gravel / Gravé / Gnarmac / Groad / ATB

Ive a several days training with Shimano whom explicitly said this, and in their training module too (Shimano T.E.C.), it also what I teach other mechanics, including one who was a bit too giddy with a Ribble and made an audible pop sound when spreading a completely worn out pads with exposed piston much to my dismayed.

Shimano being Shimano don’t mention it on their website, despite them telling us not to spread piston without taking the bleed port out and in their training video.

@hippy the bladder in the levers, not the calipers.

Several years ago Shimano don’t sell the bladder on its own until recently due to so many warranty from the bladder bursting on their levers, we send a lots because we simply couldn’t get the bladder at the time to repair it, especially during the pandemics.

We have to find old broken levers to take the bladder out and fit it in the bursted one, now a new bladder is about £9-10.

This what happened when the bladder burst (incidentally show that the person couldn’t get that part at the time).

I’m not kidding when I said some of you are incredibly lucky not to burst them, I did a couple times before realising.
