Review on 🏎️ High-performance Speed Bleeder by Russell - Model 639540 by Michael Miner

Fits Wildwood calipers with 1/4-28 thread. Good parts made in USA! They work as advertised. Remember to lower it completely before opening it a quarter turn to bleed. In other reviews I see a discussion about the function of the material on the threads. Russell says it's a thread sealant (not threadlocker) that prevents air from getting back into the caliper when it's backed out a quarter turn (see picture). It is recommended to check the valves after a test ride to make sure there are no small leaks that might indicate the part is not fully lowered.
