Thanks Ian for the reply! Any and all input is gratefully appreciated as I am flying blind on this modification.
The only thing working for me is that the donor Jeep had non-power assisted brakes and 11" drum brakes all around. Didn't check wheel cylinder diameter though. Add to the mix that the C8 has a late model rear end installed that had power-assisted 11" rear drum brakes, and the front brakes are from a much earlier General Motors product, (that way when I received the truck), I have a real brake salad going!  Thanks, David Note; It also has occurred to me that some people may be put off by taking these great liberties in modifying such a rare truck. My decisions are based on time, money and the mechanical condition of the truck when I received it. If I am offending anyone, please let me know.

It is your truck and as such you are really going to enjoy driving it.. You do what you must for safety and ease of driving.. I fully believe that to save it ,modified or not from original is a blessing.. I would only get upset if some one ,knowingly, would try to pass it off as original..then the sparks would fly..other than that ..you have my blessings..the hell with the rest of them..Enjoy..

Hi Dave,
Do what you have to keep it safe and on the road. I don't really think there are really too many complete originals around. If someone asks me "why didn't you keep it completely original", I reply that once a vehicle has left the factory it is no longer original, besides, you wouldn't have had the pleasure and opportunity to see and "inspect" this vehicle because it would have to remain in the garage for years to track down any exisiting parts that needed replacement.

David and Ian,
I agree that this is a good modification which nobody can easily see but adds to safety. Just a comment about servos - I am a great believer in them having fitted one to my WC53 Dodge Carryall standard master cylinder. The difference was amazing, it actually stops like a normal vehicle! This modification is bloody dangerous on Jeeps because of the axle twist pulling the steering bell-crank and of course the steering, causing violent swerving in an emergency stop. A safe jeep is one with lousy brakes! The Jeep one being looked at on this thread is worth trying without a boost servo as combinations of sizes between master and wheel cylinders are a little tricky (but easily worked out by a bit of simple maths before fitting). Your suggestion about boring the master cylinder(s) larger would make the pedal harder to push, not easier. This is the principle of hydraulic devices such as rams, jacks and brakes - the greater the difference between the surface area of the the pushing ram (master cylinder) and surface area of the lifting ram (wheel cylinders) the easier and more powerful it is. Of course a master cylinder of 1/4 inch bore would be as light as a feather to lock the brakes but unfortunately the pedal would have to start its travel about your armpit to push enough volume of fluid into the wheel cylinders to move them. You see this effect in normal systems when the brakes are not adjusted up closely and the pedal goes down a long way to operate them. Lang Last edited by Lang; 22-02-09 at 12:00.
