found a good source for stainless-steel Speed Bleeders
Many years ago, I installed Speed Bleeders on one of my vehicles. I loved them - they made one-man brake bleeding a snap. However, much to my dismay, they began to rust up after a few years. This is not a big deal for standard bleed screws, but it matters on the Speed Bleeder where the ball valve must remain operational. Eventually I replaced them with standard bleed screws again, since those were at least cheap to replace.
I picked up a 2006 Yukon XL Denali with 90k miles a couple months ago, so I'm new to this crowd. While searching for stainless steel brake hoses, I saw in the search results that Speed Bleeder now has stainless steel versions of their bleed screws! Like many Chevy/GMC vehicles, my truck takes SB1015-SS in front and SB1010-SS in rear. However, the stainless steel bleeders are harder to find. You can order them direct from Speed Bleeder, but they want $15 each plus $5.95 shipping, for a total of $65.95 shipped. That's a bit steep.
I found an Ebay seller who sold some of the stainless versions at a pretty good discount. He didn't carry the SB1010-SS, but I asked him to order and carry them for the Chevy/GMC crowd, and he agreed! He sells the stainless Speed Bleeders for $12 each plus $5 flat shipping, for a total of $53 shipped front and back. That's a good price for one-man bleed screws that will last the life of the vehicle.
His name is Kirby and his Ebay user name is kz10cubed. He caters mostly to the motorcycle crowd, but I'm glad he was willing to help us out. You can see his auctions with this link:
then search for SB1015-SS and SB1010-SS.
I have no connection with him; I just wanted to share my findings with my fellow Chevy/GMC owners.
