Getting ready to change brake pads and rotors since I've got the front hubs apart for the wheel bearings and had a quick question:
I've had Brembo rotors on the past few years with Porterfield R4-S pads and they've always squealed under light pressure at lower speeds (never been bothersome, I've just figured it was the pad compound and dealt with it). This time I picked up some Napa Premium blanks and another set of R4-S pads, but ordered new wishbone/anti-squeal springs and pad support plates since the old springs are either gone or almost. Also, the anti-squeal shims/backing plates are nonexistent. Didn't know how important these backing plates were in the whole operation, but since I've been running the past few years without full sets I was just going to let it go.
I was wondering, however, if I could chamfer the leading and trailing edges of the Porterfields to mimic EBC's pads. I've heard that a chamfered edge cuts down on chatter/squeal but would like to ask people with a little more knowledge before I ground up some brand new pads on the belt sander.
Thanks!
