46 Fleewood 75 brake cylinders
« on: June 12, 2017, 12:48:47 PM »
I need right and left rear wheel cylinders for a 1946 Fleetwood long wheelbase.

They should be 1 1/8 inch diameter.

Please help if you can.

Thanks,
bpowell

That's quite a large bore for rear cylinders Bill. You could with some fitting adaptions fit 1941 front cylinders, the replacements for these are 1&1/8"?

 I just had my rear cylinders sleeved by Apple Hydraulics in Long Island. Very satisfied. Turn around was 1 week. They were sleeved to my original 1 3/32. I found him online for Shock rebuilding also.

Thanks all, we think we have a couple located. Will have to wait and see what the guts look like.

These were only used on the Fleetwoods with the long wheelbase, according to the shop manual. The rear shoes were also wider.

Someone swapped them out for 1 inch ones, I'm assuming because the others aren't readily available.

The cylinders we located were not as advertised.
Turned out to be Chinese manufactured 1 inch cylinders.
We still need the proper cylinders if anyone can help.

Thanks Mike,

We need the rears and NAPA doesn't list these.

Might try to find some fittings to let us use the fronts on the rear

Hi Bill,         

The 2 links I gave you are for the rears.

Are you saying that NAPA can't get these?

Bill your right, on the NAPA website they list the left & right front and left & right rear wheel cylinders with the same parts #.

They look like all have that 1 1/8" bore size your looking for though.

Bill,
 Are yours able to be honed?? If not, why not send yours out to be sleeved.

When I use those links, I just get listings for the fronts. When I try to look up rears for the Fleetwood long wheelbase, they show nothing available.

Some one put the wrong cylinders on the car, that is why I need different ones. The ones I have are the 1 inch bores used on all the cars. Should be 1 and 1/8 on the Fleetwood.

I would like to put it back the way it is supposed to be.

Not sure if I follow this thread exactly but the parts book shows that 42 to 48 fronts (1-1/8") interchange with rears of the opposite hand for 42 to 47-75 series 163" WB cars.  Any new listing that shows these fronts available would be highly unlikely to list the very obscure long wheelbase model rears as being the same.  Even if not available new it should be easy to come up with front cores since the fronts from 42 to 48 covers all models.  Just checked RockAuto and they list fronts for 1948 and are 1-1/8".  Cadillac parts book shows these are the same as rears for your model.

I gave a link to using front at the beginning of this.

The fronts have the flexible hose that is sealed to the cylinder with a copper crush washer. The rears have a tube seat, and the steel brake line threads directly into the cylinder.
I have some extra fronts that I could use, the issue is adapting to the steel lines.
I am sure there is way to adapt them, just thought I might be able to get some that could be used as is.
I appreciate all your inputs.

In a country like ours where parts are unobtainable I've seen it done many times. A banjo is bolted on which takes the tube nut.
