Brake flex hoses
Good morning guys and ladies.
Do any of you know of a source of QUALITY (Raybestos, EIS, Wagner, etc) brake flex hoses for 1960s era MB? I simply don't trust any off brand or third world manufactured brake parts because my wife's 1961 190SL has a single master cylinder design so failure anywhere in the system results in a total loss of hydraulic pressure.
One possibility may be adaptors to allow use of inch dimensioned hoses, like the simple adaptors on my R12 air conditioning gauge hoses that allow them to be used on R134 systems.
So far servicing the brakes has turned up inexpsnsive ($4) Raybestos front wheel cylinder kits from Summit Racing and a remote booster rebuild by a company in Sacramento California for $220 plus UPS. These are way below the prices I expected to pay, especially for the booster rebuild. I expected to pay twice that just for a do-it-yourself kit.
Oddly the rear wheel cylinders are 3/4", not the size listed in factory MB service manuals (1" or 15/16"). Many American cars have 3/4" wheel cylinders so cups from one of those should take care of the rear at a fraction of the cost of a "Genuine" MB kit.
It appears that the MC uses the same kit as 1939-48 Ford cars and 1/2 ton pickups so that should be readily available in a quality brand. I don't have the MC out yet so I haven't verified the bore size. That may turn out to be another surprise.
This is an interesting car to service because it has some highly unusual design features that I've not seen in cars I've had before and have now that date from 1930 to 2005.
Thanks for any suggestions on those brake flex hoses.
