Rear brake cylinders

Hi all.

Had my rear brakes apart today for a clean up as the bus was pulling slightly to the left (not much) under braking. As I had to replace one of the cylinders last time around, as it was leaking, I thought I would check them again and found some moisture under the dust caps. I have done a quick Google and another site said this was normal.

Is this normal? I have good brakes and am not loosing brake fluid as far as I know.

Cheers

no idea

bump, so someone with knowledge replies

 

If you replaced a cylinder and bled it then there would be some residue of brake fluid in the bleed nipple after you'd nipped it up. Is this what you're seeing?

 

I am seeing a little dampness under the dust covers.

This article said a little was acceptable.

Take off the dust caps, wipe off any brake fluid residue, drive. If nothing more shows you're OK. Sounds pretty normal to me.

 

Its probably residue from bleeding if you worked on the brakes recently.
