Dumb brakes question.

Hi,

If you were reassembling an old Brembo rear master cylinder like this

then would you apply any red grease, and if so, where.

It had a load of ordinary grease in the boot, around the pushrod and the
outside of the piston, which is probably why it was sticking before.

 

If you are dismantling it, I would put just a smidgin of red on the
piston seal itself, and maybe just another smidgin where the rod goes
through the sealing boot.
