I just replaced the front brake pads on my 'new' '81 zx. Should the pads rub against the rotors all the time? The wheels are somewhat stiff (when the car is jacked up and I turn them by hand). Is there a way to adjust this? Also - the brake pedal sinks quite a bit- How can I make it 'tighter'(less play) If you can help, I would be very gratefull. I just bought my zed and I am enjoying it alot. It is a 5 - speed manual 2 seater w/ leathr interior, and power everything. THe body is black. In case you didn't figure this out when I said it is a manual transmission, it is not a turbo model. Nissan didn't make a manual turbocharged model in '81 because they didn't think the transmission could handle it. Thanks again!
