Quick question has anyone ever felt that the single chambered piston is inadequate for the braking system and felt the need to change to the dual brake master cylinders conversions offered? i would never want to to disuade anyone from changing something that had to do with safety ...but if it's good and reliable why change it. Mine is rotted out but figured a kit would work to rebuild or replce for the trouble. It's at this point where you ask is it necessary? Any thoughts?

Do it right the first time with all new cylinders and master, along with flex lines, and you should be good for at least a decade. For the price of brand new components these days, why would one bother to rebuild?

My experience is that you have 7 to 10 trouble free years with new, and 3-5 with rebuilt.

Again using Rock auto for an example, you can have the master cylinder and four wheel cylinders all brand new for only $120 plus some minor shipping to the border. Add the four flex lines and the S lines and you will be around the $200 mark. Then you can almost forget about the brake hydraulic system until sometime around 2020.

Of course, this may sound cheap, but of course you are also possibly looking at shoes, maybe drums, for sure wheel seals, and possibly a couple bearings. Don't forget to repack the rear bearings and replace both the inner and outer seal on each side. Chainging the outer only will do nothing. Oh yeah, while you have the front brakes off you may as well do those neglected kingpin bearings: expect to replace all four. The fun just keeps on going and going.

I'll assume the flex lines you mean are the ones' at each wheel? Yes! I'll change those out and flush the lines as well... just wondered if you think moving to a dual chamber is applicable here?
Hey thanks thus far for the help One down and almost striped of decent parts and the 53 waiting for the transplants!

There are four flex lines: one from the frame to the rear axle, one from the frame to the front axle, and two which run from the axle tube to the knuckles. Changing all four would be a good thing.

The little S shaped lines at each front wheel cylinder will also be seized, and they are a bugger to make. You might as well order two of those too. There is a way to undo them without damaging them, but it is sketchy at best so I won't divulge it.
Have a look at your regular steel lines as well. If they are showing signs of anything more than minor surface rust, change them too. For those you can buy those premade lengths of tubing at Cdn tire andcut and re-flare one end to make it the right length. Make sure you double flare the line: single flare will not do on a brake line.

Hey thanks Rob
Can I pick your brain a little more...? You wouldn't happen to have the part no.s for the flex lines would you...I copied the one's for the wheel cylinders as well as the master from the previous post.

Also my 53's fuel tank is a little beat inside and there is a 52 that is coated that i can possibly by to install. Not sure what the coating prosees costs but i am sure it isn't cheap. So My question is...I have a 67 with a near new looking (insideanyway) tank and thought that will plop right in But is it correct as the tank is not rounded more square and the seams are not folded welded square...? I am not really a purist but I also don't need the flack...hahaha from the others If you have an idea what does a decent tank go for now days...? Thanks Rob enjoy the day Casey

Default The 67 tank...

...is a perfect fit. This is one of the batch the Army had made when they couldn't
source originals. I've used them on 53's.
I'm having a tank repaired now and I'm up to $300. The liner is $100 alone.
Gas tanks are a pain in the butt.
The MD Juan tank is $400 but they had many problems with them. After many complaints the second lot is better but not perfect.

Sorry if I butted in Rob. I couldn't resist.
