pedal lift rod squeal

[pcpoulson at sbcglobal.net]

Don: Pedal squeal is caused by two parts rubbing together some where in the 
pedal lever mechanism. Start at the pedal brackets and lubricate every part 
until you find the culprit. Most commonly it is where the pedal rod hits the 
damper lift lever, but it could be many other places. Its a process of 
elimination.
Good luck.,
