Title: GM front pads. Asymetric backplates - which way round?
Post by: Enceladus on 16 September 2019, 03:06:39

I want to fit a new set of GM front pads. Part# 9192124.

These pads have asymetric backplates. One of each pair has a glued on shim with a rectangular window cutout, So this pad is about 0.5mm thicker. The other pad in a pair has no shim. Please see photo.

I can't remember which pad goes under the piston. Is it the rectangular cutout?

It's to stop the pad seizing to non piston side,as GM don't use copperslip, just slap copperslip everywhere, be fine then..

That.
But thoroughly clean the caliper where the pad moves with brake cleaner, then scrape it before fitting the new pads.
