I was driving through heavy LA traffic on the 405 when I suddenly discovered that my cruise control wouldn't disengage at 60 mph. I frantically tried all the obvious -- multiple hitting of the brakes, pulling up on the accelerator pedal. Braking isn't real effective in a case like this although I was able to slow some. Finally by shutting off the engine and restarting a couple of times when action demanded it -- each time the front tires "burned rubber", and with the cooperation of a couple of motorists I was able to coast off the freeway using armstrong power steering and into a side street where I could collapse.
What I discovered is that the ball chain from the cruise control diaphram had hung up on the bracket that the accelerator pedal housing terminates in. The bracket has a 90 degree bend to stiffen it with the bend pointing up and the chain passes over it. The distance between the balls in the chain somehow allowed the chain to hang up on the edge of the bracket. If the chain had been in a plastic tube to prevent this, a PO must have removed it. I created a guide over the bracket using a piece of fuel hose to allow me to proceed, and changed my pants, but I plan to deal with it more formally later.
