Well, for anyone interested, you might recall that my car's
canister-type power
brake booster has been hissing badly, whenever the pedal is depressed, and that I'd been quoted O/H prices of several hundreds, and up, for that work. When this condition occurs, with our cars, a mere reversion to manual- braking-effort results, and if so, that is NO big-deal, believe me. BiggestPITA is the hissing noise, at red lights (so, don't STOP there, I hear you say). As I never like risking sending out an essential part with the car remainingundriveable, I bought a flea-pay booster, very economically, which was claimed to be in working condition, and sent it out to "Booster Dewey", in Portland OR for O/H, at the VERY reasonable cost of $175.00.They just called and will be returning that guy to me; they say that they use a very viscous lubricant to seal up the booster's internal compression.I've asked them to send me some pics of their representative internal work, as I may be praising their product to others. They say that my 'new' booster has been tested by them to work like a champ!So, I may be interested in selling my car's canister to someone who might be interested in having IT be O/H'ed, and installed in (one of-) your car(s), too.Anyway: and here's a question for you Engineering-types: the manual brakes apparently have a different configuration of the brake pedals/system, from the power brake models (called the "aspect ratio"--IIRC) which allow for different p.s.i. line pressure ratings, between the two systems.E.G.: according to the 1957 D501 A.M.A. specs, the manual brakes have a 750 p.s.i. rating, while the power brakes have a 1,100 p.s.i. rating ; a considerable difference. (Here it comes: ) so, to what extent would a manual brake car realize an increase in braking effort/effect if a power brake's pedal-lever-connections were to be installed onto it, and, vice-versa---given, that the master cylinders are identical, which I believe that they are????
