KZ900 1976 front brake caliper help

The easiest way to bleed brakes is:

first gravity bleed. Fill reservoir and open both bleeders. Keep an eye on the fluid level in the reservoir. when fluid comes out of the bleeders, close them and top off the reservoir.

While bleeding, always keep an eye on the reservoir.

Next, pick one side. Crack open a bleeder, apply full brake, close bleeder, let off brake, repeat. Do that to both sides and you should be good to go. This method uses alot of fluid so make sure it stays full.
