how change out the front brake pads. I couldnt get the locator pin out. What size alen key?

 

If you're changing out pads on the non s calipers shouldn't it just be a matter of undoing the lower bolt and sliding the caliper up? I think it's like a 14mm isn't it?

 

I have a G37 two wheel drive car. I ordered rotors for a base model which I thiught I had. The rotors were 13 inch and didn't fit. When I called the teck line they said I had a G37x because my rotors were 12 inch. I this right! can I upgrade to 13inch? If I do will they fit my 17 inch wheels?

 

As far as I know, there are only 2 types of brakes on the G37:
Sport 4 piston front 2 piston rear:
Front: 13.98 × 1.260
Rear: 13.78 × 0.787

Non sport 2 piston front, 1 piston rear:
Front: 12.60 × 1.102
Rear: 12.13 × 0.630

 

The calipers you have are single piston and do use I believe a 7mm Allen. You cannot install larger rotors on your car because you will not be able to install the calipers.
