I just popped on my newly remastered rear brake calipers from PMB and was wondering if there was a point to the lower bleeder? I only ever bothered with the top bleeder before but now that it's bone dry I was wondering if that might be why the second bleeder exists? I will be bleeding the brakes tomorrow morning.

I think the one thing we can agree on is that these calipers with two bleed screws on the same side of the casting are a bit of an anomaly among the brake world.
I’m certainly not going to claim that I know the machine operations with certainty. Despite the logical machine operation you’ve laid out, I’ve also seen plenty of instances where machine operations are dictated by the order of machines on the line or the direction that machine slides (axis) are oriented rather than the order of operations we might do if we had flexibility to do them in a logical order. It certainly would be entertaining to know the details of exactly what ATE did and why they were willing to give away an extra bleed screw and the machine operations that produced it. |
