how do i know if my brakes need the metal sliders on the carriers?

hey i bought the 280mm brake set up, its from a corrado G60.. i got the pads and fitted them as non were supplyed and they seem a nats cock from being a tight perfect fit.  how do i know if i need the metal parts that the pads slide in?

just to note my 97 ibiza 16v has 280mms and that doesnt have any, maybe im just being paranoid lol?

Dont know but......

If the pads have built in spring clips then no

The metal sliders are often only anti-rattle devices.  If you hear a clattering over bumps - you need them.

the pads have there own spring on the back, ill see if i get any noises or nought
