I changed F pads today and L/F inner pad was half the thickness of the L/F outer.. 2mm and 4MM respectfully. R/F was equal @ 4mm. Can someone tell me how to correct this. Going to NJMP on Tues.

Lube your slide pins. If that doesn't work, rebuild or replace the caliper.

What type of lube and how much? Thanks

You can find the guide pin lube at any parts store. Look in the section where the small tubes of lubricants, RTV sealant, and similar things are stocked. Or ask for brake caliper guide pin lube.

Remove the caliper and pull the guide pins out of the caliper bracket. Clean the hole in the bracket (I use Q-tips) and the pin using a spray can of non-chlorinated brake parts cleaner. Dry everything off and apply a coating of the lube and re-insert the pin. Doesn't have to be a real think coating, but enough to completely coat the pin.

It would be a good idea to replace the small rubber boots at the same time. These boots are common to GM disc brakes and you should be able to get them at the same time as the lube.

Clean the threads of the bolts and apply a dab of Blue Loctite and torque to about 26 ft-lbs. You will need to hold the guide pin with a wrench.

Any high temp synthetic grease will work.

When I was changing the pads yesterday, the pin on the C6 is the bottom bolt, Correct?

There's one on the top and one on the bottom.
Looks like this:

that's not a bias issue, something is binding. You'll never get it perfect though, just the way it is.
