Brakes on M-37

[1953M-37]

Working on the front brakes and it is not fun getting the hose nuts loose and all the gunk scraped off. Here is my question. I found four lines that run up the frame now I know one is fuel and one is brakes to the rear and one to the front brakes. I have two that are cut off towards the front on the drivers side frame rail. What do these two lines go to? They both had rubber on the end like a brake line or fuel line and are cut by the generator.

Most likely the vent lines from the gas tank and master cylinder.

Why would the master cylinder have a vent line????

[cuz]

For water fording operations. The line would have went to the air cleaner which gets a snorkel installed for deep water fording and this keeps the water out of the master cylinder.

[1953M-37]

would the master leak with this vent open???? And where can I get brake lines?????

Your best bet on the lines is to call John at Midwest Military and have him send you his premade prebent kit. I was going to go the make my own route, and priced out the materials, the difference between that and Johns kit was nowhere near enough to justify doing it myself. Johns have the spiral wrapping like the original, the bends were spot on, and the install was a breeze.

1953M37, there are some pictures of the lines and the MC in TM 9-8030 with a lot of good reading on replacement of these components. If you don't already have a copy of this pick one up at your earliest convenience. You can get them on CD and that is better as you can print off the pages you need and not worry about geting the book dirty and greasy.

Thanks guys I'm going to see if Napa has the soft brake line for a fair price .

Just got back from Napa and paid $14.49 each for the two front brake lines to the drums.$31.08 for both [two] lines . The lines don't have the spring around the hose but thats OK for me .The most off road I will do is fire roads ....Now I need to get the soft lines off the axles frount & rear and get them replaced.......Wish me luck......Miles......

PB Blaster works great on rusty fittings. Spray on and let soak. Other use Kroil. I have used it also, but it is hard to find in my part of the country.

Miles. I would honestly think about replacing all the Brake lines hard and soft and really checking out the Master cylinder and Wheel cylinders. There is no scariest feeling in the world like hitting the brakes and the pedal hits the floor. Something to think about. Just my 2 cents

If you used another napa number, the brakes lines do actually have the armor on them. I have picked up some spare sections if I ever need.

I've never used Kroil But its actually made in Nashville. Kano Labs is Just a couple miles from my office.

I ran 100 psi of air pressure in the hard lines and all is good. I will replace all the hard lines one day [When I have cash ] but right now I'm working on getting my M-37 up and driving. I traded a running 1953 M38a1 [Willys Jeep] for a barely running and not driving 1953 M-37. So I want a driver again. And I'm making it safe. I hate when someone does poor work or thay don't know what thay are doing and you have to fix all the bad that you where told to be good. I still have to do paper work too. I have a pink slip back to 1987. Off to work on the M-37......
