I have recently replaced the master cylinder on my coupe after another push rod failure. It still didn't feel right so we took another look, and it seemed to be the peddle.
Not easy to see on the car so I took it of. I found the hole where the clevis pin go's through the peddle was badly worn.
It had worn through the hard plastic washer, and the hole in the peddle was oval.
All the ware was at the bottom of the hole due to the action of the peddle over its 25 years of use.
I am sure this ware was a contributing factor to the push rod failure by not pushing it in a straight.
To fix it We welded up the bottom of the hole so it could be drilled in the original position. The top of the hole was not worn, and still had the plastic bush intact, allowing me to drill the hole accurately.
I made a new bush out of an old spray gun fitting. Which by luck has the same ID as the clevis pin, plus it had a tread on the out side.
I Tapped the hole ,and threaded the new bush in. Flushed it of and put it back on the car.
This was not easy as the return spring has to be compressed in order to refit it.
I done this in the vice and cable tied it. Then once fitted I cut them of.
The result is a really smooth clutch peddle. The difference is amazing.
I guess you just get used to the peddle over time without noticing, and given the age of the cars I bet mine is not the only faulty peddle, so worth a look, and as I said earlier, it could be a contributing factor in the failure of the push rod.
