Brake bleed seized bleeder

[ourkid2000]

I was wondering how you can bleed your brakes with a seized caliper bleeder screw? Eric always talks about how you can bleed it back at the next closest fitting but I’m confused with this process….

Could someone give me a run down on how to do this properly?

Cheers!

Pump the brakes and hold the pedal as you normally would.
Then crack the banjo bolt at the caliper. Then close when
the pedal goes down.Then repeat.

So forgive me if I’m a little slow….lol

If you do it this way, how can you ensure there’s no air forward of the banjo bolt?

[Its me]

As long as there is pressure through the line on the banjo bolt (somebody pumping and holding the brake pedal)…and there was no air in the inside the caliper to begin with, then there is no opportunity for air to get in the system.

So lets say you’re changing your brake pads and you have to push the piston back. You go to crack the bleeder and you find it seized. How, generally, would you proceed? I’m assuming heat is a last option?

I would have sprayed penetrating oil on the bleeder put a socket
or a brake bleed wrench and tried to work it free. If still seized
reset the caliper piston slow. also try taping on it with a hammer.

So lets assume you cannot budge bleeder screw after all that work….lets go worst case scenario (short of a snapped off bleeder).

Just reset the caliper slow not to push the fluid to
fast back to the master.
