I thought so. Gets rid of the crappy steel retainer clip that was starting to crud up. Boy does it fly out at speed though, once you manage to prize it out!
spring is about the same length 4maybe 4.5" long and 2" wide as it goes over the disc (holds both pads in place) rather than just around the outside pad.
have caught fingers with those clips before bloody hell its sair as its such a small area
