I finally got around to installing my new Speed Bleeders. It was an easy install. Only took about 15 minutes, and about another 20 to bleed the brake system. These things are the most efficient way of bleeding brakes I have ever seen. There where a few very good things about these Speed Bleeders. The thread sealant is a great item on the bleeders because I was having a problem with my front caliper bleeders seeping brake fluid out the threads, when trying to bleed the brake system. The Speed Bleeders thread sealant stopped this problem. Another good thing is that the Speed Bleeders are so efficient at getting nothing but air out of the brake system that I only used about 8-Ounzes of brake fluid to bleed the whole system (front/rear). Normaly I use (waist) about 30-ounzes (or so). Plus, as I was bleeding the brake system, I could feel the peddle getting harder and higher very quickly with each push of the peddle. The front/rear Speed Bleeders I recieved, plus a bottle of the thread sealant.
