Ok I've read some threads about brakes and was thinking my master cylinder was going bad but after more searching and being under the car (found more rust:disappoin) I noticed that fluid looked liked it was leaking in that area and the caliper is stuck. It was sticking on and off and the car pulled to the passenger side but now the pedal goes to the floor. The driver side wheel has caked brake dust all over that i smacked off so im almost 100% sure the caliper is the problem.

I checked ebay and found this http://cgi.ebay.com/ebaymotors/Brake-Caliper-Nissan-240Z-260Z-280ZX-70-78-Front-Left_W0QQitemZ200206326593QQcmdZViewItem but for some reason it looks like its missing something other than brake pads but i don't know. If I replace the caliper will there be an issue with the other caliper later on or will there be uneven wear on the pads because the newer calipers are more efficient? Thanks

Get your self a couple of kits and rebuild your calipers. It's Not that tough.

i think the piston could be rusted though, and i'd rather replace the caliper for now and rebuild the original after the car is road worthy again. so is this caliper worth buying or is there something missing from it i compared it with the fsm but this will be my first brake job on the z.

Just remember you are dealing with your life as well as others. Calipers are cheep just go to your local parts store and buy a couple of rebuilds. you won't be sorry.

Just looking at that item, all that appears to be missing is a set of pads.

You are better off buying pads of your choice anyway, preferably high quality.

Also, it would be ideal to replace both callipers at the same time.

Why not use yours as cores for a pair of re-manufactured ones?

Too important to do by 1/2 measures:finger:

well thanks to the search tab i've found that i was sent the wrong caliper i've emailed the seller and am waiting for a response. i'm just going to go ahead and replace the passenger side and not worry about returning it, hopefully they really have the driver side caliper it only took 2 days to arrive too.

--just an update

i replaced my rotor and caliper today but have to wait till friday to replace the rotor on the passenger side. It was a PITA to get the hub off of the old rotor and i eventually required a hydraulic press. i also regreased/repacked the bearings and axle, this was my first time doing such an extensive job but the SEARCH bar( and fsm) makes everything easier.

I'm kinda regretting replacing the brakes though because if i'd known it'd been this simple i'd spend the $$ on a big brake kit, maybe i'll do a rear disc conversion instead.
