Hi Spec Billet 4 Calipers

[Robs-se]

Hi, does anyone know anything about the above. i have them on my SE2 put there by a previous owner.
Have been told my discs are warped slightly and as the pads are getting low will do all at once.
the pads on it are Green Stuff. I require some advice/instructions on removing caliper/pads as i have none.
also being a 4 pot will the pads i get have to have the metal inserts on the back removed.

Please help before i pull out what little hair i have left
