Well as it turns out my cars pulling to the left really hard was probably not due to my front brakes at all. It seems my passenger wheel cylinder is almost completely seized. I had replaced the drivers side back in 2011. But at the time the passenger side was responding well. Well no longer.

Just a note though. I called Courtesy Nissan and they said they had over 40 wheel cyilinders in stock for 240Z's.

so if you wanted an OEM part, they have them.

i need two, do you have the part number handy?

My canadian dealer is useless for any oem parts, numbers, etc. they couldnt care less.

Passenger side: Product SKU: 44100-R1000

Driver side: Product SKU: 44101-L1000

These are listed for 1970 to 06/1972 240Z

thanks a bunch.
