Review on 🔧 Allstar Performance ALL50855 Bleeder Screw Cap - Set of 10: High-Quality Solution for Effective Brake System Maintenance by Justin Pavelko

I installed them on the brake bleeders and lubricators. Pros: - Lots of gum in a small package. Definitely more than the flimsy rubber caps I lost from my truck. The rubber is durable and the cap is long enough to accommodate everything from shorter Zerk fittings to longer brake bleeds. While there is no internal 'groove' I do feel the cap forms over time before pumping. After making it bleed for the first time, I couldn't just take it off with my fingers. I think the tight grip was the combined result of friction and vacuum fitting. I made sure the exhaust valve was very clean before installing the cap. 10 capsules for $4.50 is pretty amazing compared to what is available at local auto parts stores. Cons: - The lack of an internal groove makes you wonder if these things are going to stay. long-term, especially shorter air outlets or mirror fittings. I'll let you know when I start losing her. Update: After 16 months of use, including a lot of aggressive double track 4WD driving, I haven't lost a single one. When I try to pull them with my fingers, they don't move. I would very much like to buy more if I need them. Update: 3 1/2 years later they are still operational and in great condition. They're also still difficult to remove when I need to get to an adjustment. I bought more to install on other cars and a motorcycle.
