Yea.. I don't know what "bench bleed" is.. other than having your hand slip off a wrench and smacking your knuckles on the bench vice!

Years ago I put a new Master Cylinder on a '79 Oldsmobile (first new MC i'd ever put on) and the parts guy told me I needed to bleed the Cylinder.. it involved hooking up little rubber hoses to where the brake lines connect. The hoses loop back up into the fluid fill spot.

With the cap off, the MC full of fluid, and the little rubber lines below the fluid level, you slowly pumped the brake pedal till no more bubbles surfaced.

That was neat and all, but in the dozen or so Master Cylinders i've put on since I haven't ever had to do it.

Maybe somebody will come along and explain what this "bench bleed" procedure is?


an idea is only stupid if you think about it rationally.
