I'm slowley getting the 352 sorted, and now that it runs sweeter I've another problem....brakes. They operate just fine with balanced and controlled stopping, but they feel to be slow in releaseing. There is no binding on any of the wheels and they all run freely. Its just that after a braking operation, they seem to take forever to release. Could this be a hydrovac problem.

Any help appreciated.

Yes, but the Master and Wheel cylinders are a good reason also. There may be deposits built up from overage fluid and rubber, with a little corrosion also. It is time to give the brakes a thorough going over.

Joel, I should have said that this is following a complete rebuild, new cylinders all round! including the Master.

You just narrowed the possibilities. There is one thing you can try, and that is to service the Hydrovac per the TM or LO with a shot of Shock Absorber oil. The packing on the piston in the hydrovac may be dry, but that is wishful thinking.

Shock Absorber oil is long gone from the shelves in the UK, sealed units and all that. Can I use a light Handy Oil, (3 in 1), you know the stuff you get at the mall for houshold use ? Whats the risks here?

Permatex sells it as Stock No 78E, it is marketed as Hydraulic Jack Oil, and lists it for shocks on the label. It was always this number, but sold as shock Oil, and marked as such 50 years ago, before the lable was changed to keep up with the times. I would not get into "home brew" guessing as substitutes may not be compatible with what is in there. Motor Cycle shops must still use it.

Joel, Permatex is not a common brand name here in the UK, so I will have to do some research. Motor cycle shops I just didnt give a thought too. Nice one.

Thanks

I hope you find some, I am going out on a limb to suggest that the UK stuff is similar. I have plenty of the proper Permatex oil and could probably send .25 litre in a safe container to you, and call it SAL. the risk of it leaking is nil. I will give it to you free, you pay the postage. It will not take much to top off the shocks.

Again the master, thanks Joel for all of your advice and expertise on these old trucks.

I am humbled, I will send you a bill when I am done talking. All this stuff is not free West of the Mississippi. Oh, BTW, I am working on a theory on how the water bucket ended up on the Bidon.

Joel, a most generous offer... thanks, but it won't be necessary. Have found some shock oil today, just as you said.. Motor Cycle shop. A good bit of lateral thinking there.

I appreciate your offer of help though.

I kind of got off track, and thought we were on shocks only. You also could use the oil used to lubricate air wrenches, and pneumatic air (muffler )chisels, but only in the vacuum chamber of the hydrovac. (do not put the air tool oil in shocks, though)
