I recently came across these while replacing my front brake lines and thought I'd share. Basically they make bleeding brakes a one person job and saved my wife a lot of pumping. All you have to do is crack the bleeder a quarter turn and pump the brakes. It has a valve inside of it that opens and closes with each pump. Seriously it's the best 20 bucks I've ever spent on the car. Summit has them here -
I'd shop around, those are expensive for two. Ames has them in their catalog for $22 - they're $9 from summit. I paid less than 20 for all four, they come in packs of two.
