Brake upgrade

I haven't been able to do much body work lately because of the rainy weather, don't need any more rust. I decided to do the rear disc brake upgrade and the 4 piston fronts.
I didn't like what was available so I designed my own. The rear uses Maxima calipers with 240sx rotors. The problem with other kits is the rotors are way to big and meant for a Mustang and or they don't provide for the parking brake.
The front uses the Toyota 4x4/4 piston calipers and a spacer I made to use the 280zx rotors. This is a fairly common upgrade and I've done it before on another car so it was easy bolt on stuff.
A lot of Z owners are reluctant to do the rear because of the stub axle removal and possible damage that often occurs to the bearings and the threads on the axles. I had a hassle as well so that was all I needed to get a better idea and so here it is.
A slide hammer is very bad for bearings!
The easy way now is to drop the rear A arm assembly and do it on the floor.
A bar is used to keep the axle from rotating and a socket/ breaker bar to loosen the nut on the axle. The axle nut is peened over but DO NOT attempt to undo that, the axle will be junk. The force of loosening the nut simply pushes it out.
The tool I made clamps on the hub and pushes the axle out almost effortlessly.
