Well here is a lil' more! While researching rebuilding boosters and such I came across Ed Strain, Inc. and this but of advice: What do I do if my brakes are really touchy? Your brakes are touchy because this is actually how the original manufacture made them. I can remember my dad teaching me how to drive and I would send him into the dash a few times.Remember that you have gotten accustomed to softer brakes from newer cars or your old brakes being so used. There are really just two options.1. You learn how to drive the car with the new brakes the way they are or 2. You can lessen the amount of vacuum assistance to the booster by clamping the 3/8″ ID hose slightly to reduce the vacuum.Keep in mind that for option 2 there is a fine line between the perfect amount of vacuum and NO vacuum at all so be careful.'' Upon reading this I went out armed with various clamps and selected a small C-clamp and started clamping down on the vacuum hose to the booster. it took a few attempts to get it just right but it made a huge improvement. Now my brakes seem much more normal without the hypersensitive assist the had before. I'm thinking for a more finished installation I could fab some sort of inline restricter. |

ARGH! Not solved yet! The self-applicaiton problem is gone, but the brake pedal still doesn't come all the way back when warm and the brake lights stay on. When the brakes are cold, the system is fine and the pedfal returns to the point that the brake lights turn off. However, once the brakes warm up the brake pedal no longer returns fully and the brake lights stay on. What the heck?!?! The only thing I can think of is air trapped in the lines that expands enough when the fluid heats up to allow the pedal to not reutrn fully. Does that sound plausible?   Will a thorough bleeding session cure the problem?

No, that doesn't sound plausible to me. I still think the problem is in your booster. |

That is possible. I believe it is the original 36 year old booster that sat outside in Seattle for over ten years. I sure that didn't so the diaphragm any good. I guess I will bite the bullet and either send it down to Booster Dewey or buy one from him outright, if possible. Short term workaround is wrapping electrical tape around the brake pedal arm so the plunger on the stoplight switch gets pushed in farther when the pedal returns to rest.

The diaphragm is one item inside the booster, which also contains various valves and valve seats and springs and breathers and other stuff that can go wrong either from use or from non-use. I had my share of '73-'75 A-body booster swapping some years back; Dewey explained there's a valve and seat in there that needs regular exercise; it really hates sitting for prolonged periods. 36 years is a pretty good run for a booster, whether it's been used or sitting. |

Add a few of these to the brake pedal:

Bungee cords are a tempting repair, but I ned to get it fixed right. I will be sending both the original booster for my Ramcharger and the original booster for my 76 D100 down to Booster Dewey. |

Call 'im first and make sure he doesn't say something unpleasant like "Ohhhhh, those...can't get the parts". |

Will do. I am about to start using this Ramcharger as my daily driver, so I might see if I can just buy one off him outright. |
