Hey guys, I have a problem with my 06 g35 coupe I hope yall can help me with. I am installing new slotted and drilled rotors, ceramic pads and new calipers. The calipers are stock but painted. I have installed the front on both sides and I have bled the brakes and filled up the reservoir, however I have very little to no pressure when driving. When I pump the brakes they will tighten up and then lose pressure very quickly. I checked for leaks in the lines as best I could and double checked to make sure everything is tightend. Anyone had this problem before or have any ideas? Any help is greatly appreciated, thanks.

UPDATE: Turns out the order to bleed the brakes isn't what I thought it was. I have now done it correctly and everything is in tip top shape. Thanks for your help yall

It might be a good idea for you to follow the brake troubleshooting section in the FSM

Did you bleed your brakes in the specified order as outlined in the FSM?
Are you using the proper brake fluid?
Perhaps the problem is in your master cylinder?
Did you check your brake booster?
Did you check your vacuum lines?

Good luck

 

Did you bleed the rear brakes as well as the front??
Hopefully you didn't run the master cylinder dry when you replaced your calipers.
