Replacement master cylinder still spongy after replacement and bleed

96 polaris xplorer 400 4wd. This model has a caliper on the tranny jackshaft.

I replaced a blown polaris red handle master with a aftermarket master. I bench bled it with my thumb to get fluid through then unbolted the old master and bolted the line to the new. I bled the upper line by lossening the banjo bolt after pumping and holding brake. I then bled from the rear, right front, and finally left front. Ive bled this at least 5 times at the calipers. Im not producing enough brake pressure to turn the brake light on. If i pinch off the line by the handle bars it gets hard as a rock. Any bleeding tricks on these? Still think their is air in the system.

Make sure the flex lines are swelling during brake operation.

Can you rent a vacuum bleader from a auto parts store?

That should get the job done for you

Either way should get all the air out
