Everything is new on the front, and all the fluid is new as well. I have an oil burner in the garage I add all my old fluid to so everything is treated with fresh fluids twice a year.

Thanks for the idea though, it has been a few months since I flushed the system and bled the brakes. Guess I'll start with that.

Anyone else have any ideas on why the right front keeps hanging? Is it the proportioning block (I wonder how much they run...)?
