Well, I just changed both cylinders out of my 95 Accord. It cost me about 50 bucks for both. Seeings how you have to bleed the whole system out again whether you change them or fix them, I would say it's worth it just to change them. That way you know where you're at with them both. Plust when you're dealing with hydraulics, and fluids, you should either know what you're doing or get someone to do it that does. Also, bleeding it is a b*tch.
