Brake pedal adjustment rod question Options

[burlybryan]

I replaced the brake master cylinder yesterday (miserable, horrible job that requires 4 hands to get the evil grommets installed). I have to MC well seated and fully tightened to the firewall. When subsequently adjusting the pedal rod to the 1mm free play, I really had to adjust it forward. Almost to the point of running out of threads. Is this common with the 914Rubber non-easy install MC? I know everyones car is different, but this seemed a little excessive. Is this ok as along as its tightened down?

Thanks for any observations.

The threads of the brake rod should be near flush with the part it screws into when the rod is properly adjusted. If you are almost out of thread there is a problem with the master cylinder.

Agreed. The reason (at the time) I was almost out of threads is because I hadn't noticed that the brake pedal stop bumper had slid to the side. So I was adjusting the pedal-to-MC play with the pedal too far rearward. With the bumper back in position, I re-adjusted the pedal-to-MC shaft and the shaft threads are nearly flush with the fitting.
