Ford 4000 brakes

Got a 1966 approx ford 4000 as a boat tractor. The brakes are very nosiey
Does anyone know how to fix

Possibly the wrong oil in the rear axle. This tractor has a wet brake
axle and the correct super universal oil should be used up to the fill
level. I could possibly be wrong here if your tractor is a red belly
4000, it may not have the wet axle. I am not familiar with the earlier
4000s, but if it is blue and has no brake drums at the end of the
axle it is a wet brake tractor.

You must have a big boat to need an anchor that big!! Sorry couldn't resist. Is it three or four cylinder?

As showcrop says we really do need to know if you have a 4 cylinder 4000 or a 3 cylinder model.
A 1966 should be a 3 cylinder but after nearly 50 years folks can be off a year or two.

If it's a 3 cylinder tractor.... get your drain buckets and dump the rear axle/hydraulic oil. Refill it with 134D or a listed equivelant that meets those specifications. Also make a point of observing how much crap and metal filings are in the oil when it drains. If there's a lot... brakes are probably shot. IN that case... you can plan on lightening your wallet by 1500-2000 for brake parts....

Seeing the oil bath brake type was covered, I'll take a stab at the drum type, just in case, as I don't know the other type except obviously how to distinguish the difference between the 2 LOL !

If you have a these, they are fairly typical drum type brakes, with all the springs, adjuster, pads, drum etc.

My drum brakes make a little noise on occasion, I did do a complete brake job, all new parts on this tractor. They are relatively simple, a few odds and ends to consider, one side has one less spring, the end of the linkage, (I'll call it an actuating cam) does wear and may need to be built up to operate correctly, mine were worn and it made a difference in the pedal where it contacts the frame of the pad, easily observed when apart on the right side, push the pedal down. If you build them up too much, the drum won't go on, I recall a little "finesse" to get that right.

There is bearing and axle seal on the end of the axle, these can leak and soak the brake pad, glaze or what have you, not sure if that would create noise, our 3600 has the same style brakes as my 850 and it also has leaking seals and the brakes did make a little noise. The hitch with the repair is getting the bearing out out, I have not done this repair, but most seem to find a way to crack, cut or what have you the bearing cage, remove and somehow press the new one back in, don't quote me, something along those lines, its been posted many times on the Ford forum.

I do know that the OEM drums are of better material, I did get new drums made in Turkey, thicker cast material but I did split one, likely horsing it when one side got stuck, under normal use they are ok I think as I got quite a few years out of them before that one cracked, I put the oem one back on.

Might just be an adjustment, best to pull the wheel and drum to see what is going on, wear, check for the seal leaking etc.

In any event, hopefully some help if you have this type.

Thanks Guys
The tractor has 3 cylinders and I think wet brakes photos attached [/img]
