I have a 57 beetle with 356 brakes. I had to rebuild the right front wheel cylinders and since each drum has 2 wheel cylinders I was wondering what wheel cylinder should I start to bleed first? The one closest to the master cylinder or the farthest to get all the air out?
Thx

Are the cylinders cascaded like a stock config? If so, open the bleeder on the last one in the chain only, not both. Depending on where your feeder line goes in, that could be the top or the bottom cylinder.
It can be a pain to get all the air out if it is plumbed with the bottom cylinder last in line but that is correct for many cars. |

Yes they are cascaded and the feeder line goes in the bottom cylinder. So I just open the top cylinder right? It makes sense that that's where any air that's left would end up when I try to bleed the system. One thing though, why would they keep a bleeder screw on the bottom one?
Thanks alot!! |

The cylinders are interchangeable so they are machined same-same. The bleeder is vestigial 8)
Keeps manufacturing costs down and parts picking easy. Otherwise there would be 4 different cylinders - each position would have to be just slightly different. |
