Wheel cylinders

[40mopar]

Update for those of you looking for 40 Plymouth wheel cylinders

Vintage Power wagons carries these and has them in stock.  I have ordered a set for my Coupe. They are slightly different from stock but they should work.

Dave,
I was able to get two wheel cylinders #17789 from NAPA, I installed the one on the driver's side front the other day, This afternoon my son and I bleed the brakes on the driver's side.  I now can drive the car again thanks to you and your advice.  I am going to replace the wheel cylinder on the front passenger side this coming week, that way, like you mentioned, I will have the same size and type wheel cylinders in the front of my 1940 Plymouth P-10 Business coupe.

Thanks again and Merry Christmas from the Catskills of New York,
Bob

 WC17789 is not a stepped cylinder and can be used on all four corners of the car.

  The hose fits in at right angles . It may be necessary to use a slightly longer hose  but it has not been a problem in any application where I have used them

The rears use a banjo fitting to attach the  brake lines.

[Bob]

I called NAPA after I read your suggestion, they are going to see if the passenger side is availible, if not, then they will call me.
So far, no call, hopefully that is a good sign.
Thanks again,
Bob

Bob,
      Get two cylinders if you can,  because of the slight bore difference, both sides should be changed.

Changing only one side could cause the car to pull to one side. Good engineering is especially important with brakes.

[Bob]

Dave,
I called our local NAPA this evening, and lo and behold, there is a wheel cylinder with the part number you posted in Fresno, CA.

I should have it by this time next week.

Thanks for the lead,
Bob

I have used  Raybestos   WC 17789 which is a cylinder used in Dodge 1/2 ton trucks.(1957)  It fits the 40 and earlier cars if you elongate the two bolt holes which hold the cylinder to the backing plate. The part which fits through the big round hole is a perfect fit and so is the hose or line fitting. It is not a stepped cylinder like the original bur there is no noticeable difference in brake action.  It has always come in within 36 hours whenever I have ordered one.
I have them on all 4 corners of my 35 PJ and have used them in many other applications without any problems.

Bob if you decide to resleeve your cylinders make sure they do them in stainless ,they will out last you and your car, the first ones i had done were in brass which was good but did not last as long as i expected, especially if the car is parked up , you guys would have more problems with that than we would here where we can drive our cars all yeqr round . as for the snow ,i live in the north island of New Zealand and the last of the snow has just gone from the mountains which are only 1/2 hour drive from my house . we are lucky it very seldom settles on the ground here,i can finaly take the covers of my tomato plants

While sitting at the dining room table with a cup of coffee this morning, I was able to answer my own question.
The number I found embossed in the wheel cylinder is the part number.  The final number in the sequence was a 3 and that was partially cut out because of the cut out where the rubber boot fits over the end of the wheel cylinder

Possible snow here later today and tonight, not really looking forward to it, but 'tis the season in the Catskills

VPW deals Dodges most, but many parts are the same.

Greetings! Go

I used White Post with great results, well worth the cost as you'll not have to rebuild the body of the cylinder ever again.

[Bob]

I called NAPA before I made the first posting, they told me that they were unavailable.
I have called Roberts Motor Parts and Pro-Antique Parts, they both told me they didn't have any.
I called Andy B, they wouldn't sell me one, but they would sell me four.

I know if one has gone bad, I can most likely expect the others to go shortly, but at this point I only want to replace the bad one.

Thanks,
Bob

I get wheel cylinders fron NAPA.....

[Bob]

Thanks for all the information.

One question I forgot to ask is should I replace the other wheel cylinders now that I have to replace the driver's side one?

Right now the only one that is acting up is the driver's side front wheel cylinder. but they were all replaced at the same time approx 18 years ago.

Thanks again,
Bob

When I can find NOS cylinders, that is what I do.  I have had good luck with resleeving also, especially with the '28.

[John Hendricks]

I have had pretty good luck with re-sleeving.  I use a company in seattle but that is just because they are in the area.  If one is bad maybe the others need the same--that way u can get all the backing plates cleaned up and the springs replaced and the rotating surfaces on the bolts cleaned up.

Question,

I need to replace the driver's side front wheel cylinder on my 1940 Plymouth.

What is the best way to go, get one from one of the companies that deal in parts for the Plymouth, or have it resleeved by White Post or a company like them that does the resleeving?

Thanks in advance,
Bob
