Jon just giving you a hard time

I'll try to find the pic I have of it outside doesn't look any nicer though.

My main reason for talking about the SD33 swap was I wan't to change things, I guess I can't ever leave well enough alone

Damn... I want to be able to STOP!! This pumping it several times just irritates me!

Yeah, stopping is a good thing! Hey Fudd, is it bad wheel cylinders that make our Braking so bad? I looked at all my shoes they look solid and even the drums are real thick. But I did not see leaking fluid from any of the wheel cylinders. Any thoughts?

I would think it would be the master cylinder... If a wheel cylinder was failing, it would be losing fluid... you would see it running down the inside of one of your tires...

It seems to me that it would be the master cylinder. A master cylinder is completely sealed off from the outside. The only place the fluid could leak out is back into the reservoir...

Ian, can you get brake master cylinder rebuild kits?

Yes I can get M/C rebuild kits, I have one in stock. Price is $35...

I agree with Jon on the MC being the brake prob. Yet, it could also just be air or water in the lines. Water is bad bad in lines, it rusts the cylinder bore and also the steel lines. If you wanted to do a complete brake rebuild on a budget you could rebuild the MC with the kit, buy some cylinder parts from me like new cups, hone your cylinders, replace all the lines, clean brass fittings, have drums turned (cheap), get new pads riveted on your shoes (also cheap) and it should be just about as good as mine with all new parts. The cylinders can leak and not be seen from outside the drum. I had 2 that were leaking but with drum on it could not be seen. They were small leaks but leaks non the less...a large leak and your brake will hardly even work. A torn boot on the cylinders and you more than likely have rust in the bore. If it is light just hone it with a special cylinder tool. It works good.

There is no water in there. I know this atleast...

I do believe the master cylinder is the fault. Mine sat for over 10 years with no fluid in the lines... How could I expect the master cylinder not to be bad?

Ive bled it several times with no improvement. I dont leak fluid, either...

Im considering removing the master cylinder to inspect it. If its fine, good. But it wouldnt hurt to look anyhow...

I will get back to you on the Master cylinder rebuild kit. If Jon wants it, let him have it. I could wait till the second time around, or if all else fails, go to the parts store and see what will fit!

Yeah, Fudd

I will get in line for the rebuild kit too for the MC. Do you have some instructions the send with the rebuild kit(I would like to do this only once)? By the way $35 seems very good what does the kit consist of?

Jason, I P/M you

It seems to me if our wheel cylinders were bad, they would be leaking fluid...

I am pretty convinced its the master cylinders...

Sorry to bring up an old post but!The nissan/Datsun pickups before the Hardbody had the extended tube power brake canister. I once took measurements to see how close it would be to bolting up to my Patrol. It was close but I'm thinking maybe like Jon my clutch master would be in the way. Can't rememeber. Also when switching brake master you have to decide if you are going with 4 wheel drums or front disc/back drums. There is a difference in master cylinder plunger design. I found this out when looking up a front disc conversion for my 62 Chevy pickup. Something to do with holding some pressure on the front lines w/discs? I would have to dig through my saved documents to found out.

Interesting point Keith. I have a friend that has an old 720 pickup. I'll try to talk to him today for some measurements. You also bring up a good point about the frond brake canisters. It would be larger for sure. But how much more presure would it generate? Would this be an advantage or just start blowing front wheel cylinders.

I think it would be a problem of front brakes locking up easily while the rear would be barely working at all. That would make you have to constantly replace front brake shoes meanwhile the rear ones be barely worn.
