Terry McTaggart here. Thanks for all the advice; I have fixed the problem. I pulled the rod, along with the piston, out of the master cylinder thru the passenger compartment. With a LOT more force than I thought necessary, I was able to separate the rod and the piston. As the wizard, Mr Riehl said, the rod did have an O-ring on it, keeping the rod in the piston. The act of pulling the rod and piston apart did not do wonderful things to the O-ring, which now has seen much better days. The 300F now as both brakes and brake lights. By the way, the top inside nut on the master cylinder is a bitch to put back on, due to the rams. Happy Spring! ************************************** See what's free at http://www.aol.com.
