Rear brake bleeding

[Vanderstel]

I replaced the drivers rear wheel cylinder and tried to bleed it with a vacuum pump. But I still have air in the line.

I'll try again, but what is this device on the rear axle housing? See arrow...

Does this prevent vacuum bleeding or do I need to use the "pump the brakes and open the bleeder valve" routine?

Looks like the vent, they use it to hold brake line block.

Use the pump the brake and open the bleeder method, start with the right rear. You probably introduced air in the other side with the vacuum bleeder. No need to worry about the front if it's 66 and up.

That's a dust cover for the axle housing vent. Does not affect the brakes.

I guess some air snuck into the other side. I have to replace that cylinder too, so I'll bleed both sides.

Also, I believe there may be a little metal pin on the brake proportioning/hold off valve that needs to be held out while bleeding the rear brakes. Check a factory service manual

Rear brakes are inter connected, so if replacing the rear brake both sides, do that first , then bleed passenger side first then drivers side ! I usually add a piece of vacuum hose to the bleeder if bleeding by the pedal technique, with the hose in a coke bottle with the end in some brake fluid , watch the fluid in bottle , no bubbles, then your good , go to other side and do the same ! If the car has a dual reservoir, then the rear is complete! Hope this is clear and helpful!

Very clear and to the point. This is the way.

bleed pass side first

I always loop the bleed tube high and then down. Wheel cylinder pistons pushed fully in, reservoir full and crack the GREASED bleeder screw.

OP hasn't told us what year, front discs? or what not. The only car I've fought with was the Bird, with it's hold off valve and nonsense for disc/drum. Had to get the Wife pumping on that one..

67 Satellite, drums all the way around.
