Ok so l have an 03 Infinti G35. l hate my brakes! When it is not the front one's, its time for the back one's! Why do they run out so quickly in this type of car? Anyone else with the same issue?

It is probably more related to the way you are driving. Do not rely on your brakes all the time. If you see a red light ahead of you start coasting so you do not have to come to a stop before it turns green.

Why did not you replace all 4 when you did the front. Sounds like your brake problem is really a bad decision.

Infiniti learned their lesson by putting racing brake pads on their cars, they had to extent the warranty because they were wearing at 15k. Your car has a weight ratios 50/50 mix that is why your brakes wear so close. Brake dust was a common complaint but nobody complained about the car being hard to stop, that is for sure.

Get use to it. Infiniti is are notorious for wearing out brakes.
