** At a Dead End ** Hello All.... I am at the end of my rope with this problem. Had a rear right inner brake pad worn down to nothing. Changed both rear rotors and pads, replaced and lubed slide pins and still same problem... Caliper piston not re-tracting fully. Then I even changed the whole right rear caliper and the rubber brake line. Still same problem. I cant figure this out. Is this a master cylinder issue at this point? Thanks to anyone that had this same problem and can help. All 3 other wheels totally fine.. I'm out of ideas. 2009 Infiniti G37x sedan. Plain stock single piston rear brakes. ( No Brembo)

 

Here's the FSM, check link "BR" for the brake system.

Sure sounds like it's something amiss w/ the Master Cylinder/ABS proportioning
system. Probably best to take it to the dealer, a Nissan shop may be cheaper.

 

Thanks so much for the reply. Yeah I think its time for the dealer as I am out of ideas. I found some "ask an Infiniti expert" internet site that will answer my question for $18 but I think at this point I'm throwing good money after bad. Whats he going to tell me anyway that its an ABS issue. I cant fix that anyway!!
