Re: Brake adjustment

[Jad.Duncan@GAT.COM (Jad Duncan)]

More info.

The car is in excellent condition with no rust or corrosion (babied San 
Diego Car) and the brakes seem to work very smoothly.  How did you get the 
rod out to clean/adjust.  That seems to be my problem.  The rod turns when I 
put a wrench on the U-bolt that goes around the pedal.  Is there some lock 
mechanism or release that I am missing.  Should the U-bolt turn easily 
around the rod? or should the rod not be turning?

Any advice would be greatly appreciated.
