Hi folks
I've just been cleaning my calipers, put rubber grease on the pistons etc. When I was pushing them back in, one of them popped out - not completely but enough for a few drips of fluid to leak out.
What consequences might this have? Not sure if any air got in the caliper or not.
Any advice?

When you say popped out, did it go past the seal?
-
bleed the brakes dont risk it !
20 minutes of messing around is better than weeks of being deaded because your brakes stopped working and you hit a roaming cow

Think it must have edged past the seal (or at least part of it - was at a slight angle when it happened) in order for the bit of fluid to leak out. It slipped straight back in though & was only out of place for a fraction of a second.
Would bleeding remove any potential bubbles in the caliper? I think I read about a technique on here where you remove the master cylinder cover, tie the brake lever back & leave it for a few hours for bubbles to migrate to the top of the system. Or it could have been a dream, I'm not 100% sure. Anyone else heard of this?

If it's the rear caliper on a 600 I wouldn't bother, they're shite and ain't gonna stop you hitting a cow from any culture, bled or unbled! :b (Says he who's going to be giving his 600 rear caliper some maintenance love this weekend)

Yep you heard right, I normally do that trick after my brakes have been bled, it tends to sharpen them up that little bit more, so definitely worth a go. Best to leave it over night though.
If you loosen the MC lid make sure the bike won't get touched and I normally stick loads of rag around it in case of any accidental spillage.
I've been known to leave something on my seat to remind me as well, I'm not a morning person!

If the brake feels normal and not spongy you haven't let enough air in to be a problem. But bleeding it won't do any harm either way.

I hear what you say about the rear caliper. Just spent a couple of hours on that one alone. Pushed the pistons out & cleaned them. Would they go back in? Hell no. Used a G-clamp to apply pressure. Broke the G-clamp! Used a bigger G-clamp. Faffed about for a l-o-n-g time & finally got them in far enough to get it back on again.
Haven't been for a test ride yet - will do this over the weekend & report back with the results. Right now though it's time for the pub!
Cheers all!

Shouldn't be that tough to push back in at all.
