Technical Stickey Calliper/Piston

[Trancendental]

Hello all, more technical questions for you If the Tipo had a Stickey Calliper or Piston how would I tell it was stickey and what would I use to fix it? WD40? 3M Grease?

And where would I apply it?

Ta very much

If you are having brake problems, with pads out, push piston back in and get someone to lightly apply the foot brake. Does the piston move ok? If not, take piston out and polish it with some emery paper. Smear with brake fluid only, nothing else. Your problem is probably the pads not moving in the carrier properly. Get rid of all the crud, and smear with copperslip on carrier face and pad edge.

Just to clarify I believe my problem to be a piston that is not returning "at all" after the brake pedal is released.

What do you mean by "pads not moving in the carrier properly"?

Pads slide in the carrier when piston moves out and clamps the disc, yes?? If the piston was right out, you would have serious brake problems.

oh I can visualise now, you mean the pad slides inwards and outwards as in towards the disc when braking and then outwards again when released. I thought you meant up/down/left/right or something.

If the piston was right out though that would mean I would be braking constantly. could this not be the issue, even if it was just lightly?

I'm still waiting for my spanner set to arrive before I can dismantle anything so I'm just mentally preparing so I don't fraff about.
