Beatles65 Posted September 28, 2012 Report Posted September 28, 2012 The brakes on my 1946 Dodge were fine when I purchased the car and drove it home, I had it in the shed for a few weeks and when I pulled it out the brakes required two pumps to stop. Now you have to pump it hard twice to get anything. The previous owner rebuilt the wheel cylinders, but didnt do anything to the master cylinder because it had prime. I tried bleeding the brakes and still no solution to the weak brake. I believe the master cylinder is bad so I want to take it off and either rebuild it or replace it. I did part of the take off tonight. Does anyone have any pointers as to get the thing off, it seams that the brake and clutch pedel have to go with it when coming off? That thing doesnt look too easy to remove, I removed the three bolts that hold it on the frame, but from there it seems that theres no room to pull the pedals through. I was wanting to use this car for my sisters wedding in two weekends, but who knows what'll happen! How much do new Master Cylinders cost and where can I get one? Napa, Advance Auto Parts, any of those places? Any Pointers regarding removal would be great! Thanks! Quote
Suess Posted September 28, 2012 Report Posted September 28, 2012 Look at the pedals you should see a,bushing or rod that runs through them, they will have a c-clip or Jesus pin. Remove the pin and knock out the rod. Be sure to check the bushing for wear. This will make it easier to remove the mc Quote
james curl Posted September 28, 2012 Report Posted September 28, 2012 Remove the floor covering then you can see that it has a removable floorboard that when removed exposes everything from above. It is worth the time to remove the mat or carpet in order to remove the floorboard. Then you can remove the master cylinder and pedals as a unit. The trunnion pin is a press fit in the master cylinder and will sometimes seize there and be almost impossible to remove from under the car. So save yourself some grief and do it from above. Quote

You can get your mastercylinder resleeved with either brass or stainless and will have a permanent repair. I use a company in California for all my brake stuff.

WatchingWolf Posted September 30, 2012 Report Posted September 30, 2012 I don't believe the Dodge floor lifts out like a Plymouth Napa Reman Master cyl is $108.00 part number NMC P33792 Napa Master cyl rebuild kit is $17.68 part number UP 143 The website shows both in stock at the warehouse. Quote
garbagestate 44 Posted September 30, 2012 Report Posted September 30, 2012 If you opt for a new mc you might want to find somebody with a press to remove and re-install that carrier pin. Quote

Ain't it nice to have that kind of access!...reminds me I need to find some replacement foam/seal for between the pan and the floorboard! Quote
WatchingWolf Posted September 30, 2012 Report Posted September 30, 2012 huh...I concede. The floor in my 50 is one piece. I'd snap a picture, but there are some pretty shameful repairs hidden under that floor mat. Quote
Beatles65 Posted September 30, 2012 Author Report Posted September 30, 2012 I was able to remove the floor in the old Dodge and pulled out the master cylinder from there. It was dirty in the cylinder so I plan on cleaning it up and getting the rebuild kit from Napa as well as a remanufactured one just in case the rebuild doesnt hold. We need the car this weekend for my sisters wedding so I thought it wouldnt be a bad idea to have a backup rebuilt one if it doesnt work with my rebuild. Hope everything goes well! Quote
