It has been 3 years with the Demco Dolly, time to flush the Brake fluid

[Kevin D Pem]

Probably the wrong way.

Typically I changed the fluid when doing wheel cylinders. Only one time did I do it without new cylinders. In that one case I sucked the master cylinder dry. blew the lines empty with Air and bleed valves open. closed valves filled with dot 5. Then drained and refilled with dot 5. Never had a problem but suppose I could have.

Kevin, thank you for suggesting the vacuum method. I have had this MityVac tool kicking around my shop since the 80s. An important tool for when I bled the brakes of the road racer, weekly Haven't touched it for 20 years or so.
