Am installing new front Brake Performance Rotors and Pads on my 2010 HHR SS Brembo based on good feedback from this forum. Unfortunately, their tech support rep was unable to provide feedback on whether they recommend grease between shim and piston, and what the Brembo mount caliper torque setting is. They referred me to 'my mechanic'.

Most importantly I think is the caliper mount torque setting - anyone have it? Searched the forum but unable to find. TIA

Oldblue - do you have the breakdown handy for the RPO codes J42, JL9 and JM4 - ie: which model/years?

You know me, I just hate using the search tool.

Cool - I'll update the Torque Value thread. Thanks.

The Brembo package is RPO J56(not listed on the torque spec page). After searching over at CSS forums, it looks like the recommendations are 96 lbs. ft.(same as RPO JL9).

I have heard people profess the use of both grease and glue between the pistons and the shims. Personally I have never seen a difference, so I leave them dry like the factory.
