We get a few in for service that are fine once bled, but after several times cycling up and down they can begin to slow again.
I’ve got one that does this, though it doesn’t suck down, it just gets slower until it stops moving at all.
Weird thing is, I get it home in the warm and it starts working again and can go back to full speed even.
I’m not sure if it’s the temperature (done this in not that cold conditions and the very cold), or just through use and stopping using it for a bit seems to help. Except now where I’ve not used it for weeks having taken it off the bike and now it won’t budge at all.
Noting that I swapped the LH lever for an older RH lever and I do suspect the RH is iffy.
