In reading up on all the many posts here about disc conversions, I see multiple postings that suggest removing the residual valve from the original M/C, AS WELL as adding a 2 lb and 10 lb valve if retaining rear drums..... My question is, isn't this a redundancy? or an extra step, for at least one of the valves that is being added? If the residual pressure valve in the MC is 2lbs.... why not then just leave it in, and then go ahead and add ONLY a roughly 8lb-10lb valve to the rear? The maths line up.... therefore, I am either missing something or understanding these valves incorrectly. someone straighten me out?

wow that's a great resource. Thanks Tod Fitch!

Searched around a bit and cannot find the answer. Can anyone tell me the size of the rear outer axle nut on my 1949 plymouth? I'm at work now and hope to remove the drums with puller etc this eve, but must gather tools from here prior, and I'm forgetting what the size is.

thanks for the guidance folks! even with the frame mounted clutch pivot, I did have to remove the floor pan. M/c is now rebuilt and all is coming back together slowly

well as an update.... I attempted removal from below (without removing floor pan) It turns out this has proven to be geometrically impossible in my setup. due to the shape of the brake pedal arm, and location of the m/c, there isn't enough clearance to "thread the arm down out of the floor and drop the m/c at the same time. So removing floor pan. Have removed all floor pan bolts, brake & clutch pads. Now just to somehow get at the throttle linkage bolts from below... and holy **** wow they are hard to get at. that's a tight spot! I'm giving it a rest for the night.

Hi Earl, Yes that's going to be my set up on this 49 ply also. I think I'm going to attempt what you and a few other have done here. Leave the brake pedal "arm" on. But remove the foot pad. And pull the M/C out from below with brake "arm" attached. I understand that removing the floor would give me a way better view of everything. But I see now this isn't nessecary with the frame mounted clutch. Can't wait to get home!

Yes shel_ny that what mine looks like. I guess I assumed I could remove the pin and pull the master cyclist out from below the car without having to take the brake pedal arm with it. While I WAS able to get the pushrod part of the brake pedal arm off, the larger pivot point isn't able to be slid out horizontally due to no clearance between the frame. Haven't managed to get back to the car to get the floor out. But I'm sure all will come out easy one the floor pan isn't in the way. So much help here thank you forum!

AH, I read 1949! this will explain the differences I'm sure! Although soth122003 may be right. I guess I'll find out once the floor is off Thanks!

this is such great help folks. thank you! ALTHOUGH... strangely enough, Im certain my linkage looks slightly different. The clutch linkage and/or clutch pivot point seem to have no relation to the master cylinder on my car. I have "blanked out" (in yellow) what IS NOT present in my car in the attached picture. Maybe the fact that this is a Canadian 49 Plymouth presents a few small differences? Ill get to work on taking the floor off regardless, this eve. thanks again

oh this helps a lot! well thank you. I don't know why my shop manual doesn't mention this anywhere?? it has beautiful descriptions on how to disassemble the master cylinder itself , but no mention of getting it out/removing floor pan etc. I guess id have a question regarding removing the floor pan... I cant picture it now, away from the car, but will I have to disconnect the throttle linkage and remove the actual foot pads etc to get the pan out?

Hi Don, I have indeed read up on servicing yes. My intentions are to inspect my m/c and determine if I should rebuild or if a new one is in order. Regardless, gotta get it out of the car first of course I don't see anywhere in my shop manual where it outlines how to get it out of the car.

Hey guys, Lost my brakes on my car a few weeks ago! so of course parked it till I address the issue. Cant seem to figure out what to do next to get my master cylinder out. Just need some small pointers I'm sure... I'm working from below the car Here's where I'm at: Jacked car up Removed brake lines from M/C Removed the three mounting bolts Removed pedal return spring from pushrod Removed brake pedal arm from pushrod now the master cylinder is loose up in there, but cant determine what needs to come off next to drop this thing out. Brake pedal "pivot" is still attached to the m/c cant see how to disconnect this with such little space.. Thanks in advance

I guess I was confused a bit, because it is also present "near" the ignition switch on the diagram. (a lead going from the switch TO the circle with an X) I guess just a bit deceiving as it seemed "separate" from the switch itself. (rather than, in my case, a position of the keyed switch) Thanks that seems to make sense now based on what I'm looking at under the hood. Yours is different eh? do we have the same car? my wiring diagram seems to line up pretty good for me so far.

The wiring diagram for my 49 Plymouth special deluxe (p18) Shows, in a few spots, a "circle, with an X through it" what does this refer to? I'll add a link to a pic of what I mean... Thanks in advance

Decided to tear into my turn signal switch on my 49 plymouth, As it had stopped working awhile ago, and recently started smoking while ignition was on!! I'd rather have a car WITH turn signals, as opposed to a car without turn signals and burnt to the ground. My beginner soldering skills produced a success this time Dont know how to make thse pictures smaller.... they look pretty large in my browser. two of these wires are hanging on by just a strand, causing all kind of shorts etc. the black one (power lead?) isnt even connected and was grounding to the body. the finished product before intallation
