Finally switching over my brake master cylinder from single to dual on my 1965 Belvedere. I'm looking to save as much money/time as possible on this, since the car is my daily and I am a recent grad on a budget. So the more parts already on the car I can keep using the better. I know that some of these questions may have been answered before, but I also know that '65 was an oddball year, and I don't have the money/time to be wrong about this.
This is the new cylinder I want to order, which is a stock style replacement for the 1967 cylinder: http://www.napaonline.com/Catalog/C...-Master-Cylinder-New/_/R-NMAM1874M_0498099522
I have been told that the 1967 cylinder will bolt up directly to the same mounting plate as my stock 1965, and that the push rod from my 65 cylinder will slide into the 67 dual without issue. Is this true? (or will my push rod be too short?)
I have inspected my brake lines and determined that they are healthy enough to last for a while, will eventually be replacing them with a new pre-bent dual master conversion set from Inline Tube when I have some more money and time in a month or two. I would wait, but my single master cylinder has developed a leak under the dash and I don't wanna wrap my car around a tree on my way to work. Brake pressure is still good and the leak is very slow, haven't actually seen it leaking, just felt some residue on the carpet and the brake fluid went down about a centimeter over two weeks of daily commuting (I have been paranoid about checking my fluids since if the single master goes you're hosed pretty much).
Since my car has drum brakes on all 4 wheels, I have been told that I can adapt my current lines relatively easily and without a proportioning valve, blocking off the rear line from the junction block of the current lines and then adding an extension to go from my rear brake line to the newly added 2nd brake reservoir outlet, and possibly a new line from the front brake junction box to the cylinder if the stock line cannot be bent/repurposed. What parts should I order/look for to make these new connections? Are the stock fittings on my current brake lines and on the outlets of the new 1967 Dual Master the same/compatible?
