G37 sedan rear right brakes
 

Seems like my rear right brakes on my G37 xS is wearing faster than other 3 sides. Looking at the pads, right rear is worn out significantly more than others. Any suggestions

Sticky caliper?

unless you suspect bad calipers just repl the rear brakes.

I'm going to replace the pads today and make sure the sliders are good. Hoping it's just dirty pins preventing it from retracting properly.

Spray a lot of brake cleaner around the pistons while moving them, might be some buildup there that can cause some sticking as well.

Update: I replaced the pads, which were just about gone compared to driver side. I cleaned the pins and greased all moving parts. Looks like the seal/boot on the piston has light tears in it. I proceeded anyways with the pad replacement as it is my daily. The piston itself did not move easily with the clamp when putting new pads in which seemed like a red flag to me. Anywho, the next day after driving back from work (stopping power is good, in Neutral the car moves easily on the slightest incline) the passenger rear wheel was a great deal hotter that the rest. This boggles my mind because for it to be hotter, means it is binding and/or stuck yet the car freely moves in neutral.

Need advice. I have new seals/piston coming from Rockauto just in case.

I will jack the back up and try to spin the wheel by hand.

OK so left side spins fairly easy, almost no effort. The right side sure does require effort, there is binding going on.

Has anyone rebuilt their calipers? I've never done it but from seeing videos it looks simple. I've done pad/rotors bunch of time and I'm handy so shouldnt be difficult.

Update: For anyone looking to rebuild their calipers, do it. Super Easy. I only did the right rear, might do the left rear at some point but it looks good still. The whole job too less than an hour. Sure was handy having my wife operate the brake pedal to bleed. I had her pump the brake until the pressure popped the piston out. I clamped the hose with a hose clamp. cleaned out the inside of the caliper. Removed the old seals and oiled the new piston up with new fluid and re-installed it all back. bled the brakes 3-4 times and all is good. Cost me less than $20. I got the seals/piston from Rock Auto.

That wheel no longer gets hot from a short drive. The piston had corrosion on it and the seal are torn up. I used plenty of brake cleaner and cleaned the inside real good. Installing the new piston was super easy, just make sure its straight and well oiled with fresh oil. Throw the seal around the piston and make sure the bleeder is open and push it into place. Press the seal into place by pushing on the metal ring of the seal. Re-installed caliper and begin bleeding process.

I'd love to see a DIY on a caliper rebuild...I've wanted to give mine a refresh but I'm too chicken to ruin the mechanical bits on my Akebonos
