I bought an early zx rear disk conversion kit some time ago for my 280Z, and have only recently installed it. The install went smooth, but I have since ran into a few problems. The first time I push on the brake pedal it goes almost to the floor, if I pump it again it's at perfect pressure. I've ran a 32oz bottle of brake fluid through the system using the "clear hose in a bottle" trick, and bled the master cyliner so I dont think that there is any air in the system. The E-brake lever on the drivers side isn't working, and I don't think that caliper is clamping as hard as the rest. I have two rebuild kits that came with the conversion but I've heared that these calipers are hard to rebuild. I don't want to buy a zx haynes manual just to rebuild the calipers. Has anyone done or could someone do a good write up on how to rebuild calipers. Ive searched but I haven't found anything very helpfull. Thanks.
