My front brakes are Sh1t

[Jimmygixxer]

that just may be the one then?...strip it down again and check it over!!...you should easily be able to push them in with you fingers if OK!! ...

I remember that it was harder to pump out than the others, is the only way to fix it new seals or do i clean around the seal and re grease?
I never thought one piston would cause sponginess and i thought as the seals got older they would actually get smaller with wear and create less drag, but then again what do i know  :lol
