They work great for brake line bolt that goes into the caliper!!!
After buying brake hose plugs from the local suto parts store and having them not even work at all. I decided to try these and OMG they are AMAZING !!! I recomend these to anyone who needs to do brake work and wants to stop brake fluid from draining all out. These plug the hole through the bolt on the line and stay in place and stop all fluid from coming out while you work on your brakes.
