I understand rear braking can be enhanced by replacing the stock brake cylinder on the mid axel with one that has a larger bore. Can anyone help me with a part number for that cylinder?

Glen,
I cannot say that it will stop that much better, but lessens a chance o
sliding the back two.
Maybe by not sliding the rear, there is always a chance that you can stop
sooner.
All the weekends we spent slamming on brakes to better understand the
effect of avoiding skidding has been an education in its self. This concept
of having different size wheel cylinders was first published by Fritz Slama
back in 1985.
I can tell you that between myself, Nick G, Chuck A, and Rick F.
we have more experience testing rear brakes.
Others like to think they have done
Drop me a note and I will get you the part#.

Glenn,
Yes, that will enhance it some, but want to make the rear brakes work right? Get the "Reaction Arm" set aka floating rear brake kit and do that. Yes it is more expansive, but it is worth it - IMDCO. If you will be at Brason, drive and brake mine. You don't have to mess with anything you don't want to, it still has a parking brake and the original master cylinder.
