Hey guys. Long time reader first time poster here.
Iv got a 04 g35x and last week a caliper froze up messing up my inside brake pad and the rotor. Iv replaced the calipers on both rear wheels, the rotors, the pads, and the rubber hoses. But the rear brakes still drag up on the rear. They dont grip hard just hard enough its hard to move by hand, but once thw brakes warm up they really start to grip on test drives. If I take off the calipers they spin freely so its not the drums. If I pump it a few times and crack the blender they don't squirt out a bunch of fluid, maybe a drop or two. Slide guides move freely and easily. When depressing the caliper cylinder there is a small amount of force it seems to take then it moves fairly easy inward.

I'm at a complete loss here. It seems its just dragging a tiny bit and then they start to expand and drag more. Any help would be greatly appreciated


Edit. Only the rear passenger caliper was originally froze up. The driver side brake pads looked new. Now the driver side is the side that gets the hottest

The driver side rear is always hotter

 

Sounds like a blockage in the brake lines. With the rear lines cracked, the brakes should bleed easily.

If you unbolt a line from the caliper, does fluid come out easily if you push on the brake pedal, or is it just as stiff?

 

Bleeds easy and to the floor with a steady stream. Turn the motor by hand? What do you mean? I don't think I could turn any v6 engine over by hand.

 

Wrong thread. That post was meant for someone else. Ignore it

 

Then there is an issue with the calipers.

Are they installed on the correct sides?

 

I did them one at a time and made sure it was right. But, Is there a picture I can see to make double sure as I'm not going to rule anything out.

 

I'm bringing the calipers I. To get checked maybe swapped out today.

 

I don't have a pic, but the bleeders need to be positioned as high as possible on the caliper. It is possible to install upside down in which case you will trap air.

However, i don't think that would be the source of your dragging brake issue.
