Hello, I recently bought and installed 300zx calipers but I'm having an issue for some reason now my whole system does not have breaks the pedal doesn't seems to hold pressure its weird I thought it was air in the system but i bled the breaks about 5 times now still when the car is off after I pump the breaks there is some pressure build but but then when i turn the car on nothing. If anyone can help that would be great thanks

 

i cant remember but arent there two bleed screws per caliper on the ZX calipers? maybe your just bleeding one side of them.

 

There is only one bleed screw per caliper. When you installed them, is the bleeder screw on the top or the bottom. You may have them reversed.

 

^^^ My money is with you, I bet the bleeders are pointed down.

 

yes the bleaders are pointing down are they supposty pointing up?

 

Yeah, you need the bleeders on top. I ran into that problem too. Switch them around and you should be good to go.

 

x2 i did the exact same thing, i must have spent $100+ on brake fluid trying to figure it out, its pretty easy to reverse them. just remember that air is bouyant so your bleeder screws always have to be in the highest point/pointing up to get the air out.
