I need your help
So I have a G37s coupe, 2008. I have a problem with my brake system which even the Infiniti dealer could NOT fix.
Three months ago I have changed the brake pads by myself, but mistakingly instead of replacing the brake pads with the right way, I OPENED all of the four calibers a part and most of the brake fluid came out of the system, which I know I should not do. later when I put the calibers parts back togather and test drive the car, the brake pedal goes all the way down almost to the floor. but the car does stop. I already bleed the system from air and changed the brake master cylinder but the same thing is still happening.
so what do you guys think I should do?

Also, verify you don't have any existing leaks. Look very closely at the piston seals on the calipers. They may have been damaged if you disassembled them.

Just say no!!!!!

No dealer worth their name would release a vehicle with something as serious as a fault in the brake system without giving you an estimate of repairs and having you sign off declining the repairs.
What does it specifically say on the invoice?
You need to get this addressed immediately before you cause a wreck!!

There's also the ABS that needs to be addressed if you replaced the MC, never replaced my MC but I've read that that also requires a bleed if the MC gets too low in fluid or the MC is replaced.
Sounds like there's still more to be done w/ the bleeding. Might try a Nissan dealer.

Holy water doesn't work well in braking systems.

If dealership bled your brakes and your pedal still hit the floor then something is wrong with your calipers. Something to keep in mind is the seals will require replacing every time you break them apart. Please refer to pg.41 with all the (X) marks which symbolizes replace after each disassembly. Hope this helps.

sounds like the caliper piston seals may be leaking fluid pressure causing the low pedal. check to see if those piston seals are available to be replaced by themselves. otherwise you may need to buy a complete caliper. lesson learned the hard way, if you don't know what you are doing keep your hands off it.
