wayfarerstranger Posted June 24, 2009 Report Posted June 24, 2009 do all p15`s have the smaller brake drums 10" and are the same as the 49-52 plymouths .. Quote
BobT-47P15 Posted June 24, 2009 Report Posted June 24, 2009 Isn't 10" considered standard and 11" heavy duty? Quote
desoto1939 Posted June 24, 2009 Report Posted June 24, 2009 In 1939 The Chrysler, DeSoto and Dodge all had the 11 x 2 inch brake drums and these drums. The Chry and DeSoto had the bolts that used right hand thread on all wheel and the Dodge used the studs on all the drums. I have a 39 DeSoto with the original drive line and front end.

Plymouthy Adams Posted June 24, 2009 Report Posted June 24, 2009 P12 was the last Plymouth to get the 11 inch brakes according to my books but I did not further forward than 1954 there is no mention to the heavy duty application whatsoever..the larger Dodge, DeSoto and Chryslers did have the 11 inch brakes as stock...Some of the smaller Dodge chassis's did have the smaller 10 inch brakes..am thinking Wayfarer..short wheelbase model shared with the Plymouth Quote
Plymouthy Adams Posted June 24, 2009 Report Posted June 24, 2009 Well Norm..I glad you had the larger brakes and ever happier for you not to have ever had a problem for the the master catalog does not list anything for replacement..I am truly always amazed at the difference your car is compared to the ordinary everyday run of the mill P15 Quote
Niel Hoback Posted June 25, 2009 Report Posted June 25, 2009 I put front drums from a 53 on my 48 several years ago. I've using them since. Someday I'll tell the story of trying to get them on an airplane in a gym bag. The x-ray showed them as Claymore mines. It was afun trip. Quote
RobertKB Posted June 25, 2009 Report Posted June 25, 2009 Never heard of 11" on the P15, D 24, D25, or later Plymouths and Dodges. Any I have seen are all 10" and the only 11" I have are on my '38 Chrysler. I did have a set of drums from a '38 Dodge but they are 10". Norm, maybe someone in the distant past needed to do brakes and had a good set of 11" and swapped them out. I know Rockwood had the reverse happen on his Chrysler which started life with 11" but now has 10". Lots of strange stuff happened to some of ours cars before we got them. Quote
wayfarerstranger Posted June 25, 2009 Author Report Posted June 25, 2009 I really thought most all Ply`s & all post war Plymouth`s had the 10" my wayfarer`s have 10" with the studs & lug nuts now the 49 Dodge Woodie i have has the 11" brakes and the wheels are deep dish they have a 2" lip all my others have 1 1/2 lip . would not mind having some more of these deep dish wheels if i could find some ..anybody know what cars they came stock on ?? maybe large chryslers & desoto`s ???.. also the D24 i just took apart had the large brakes & i believe all had them ..

Plymouthy Adams Posted June 25, 2009 Report Posted June 25, 2009 only thing I said and still claim is that all my source books make no mention of 11 inch brakes on a P15...and as a disclaimer I have no idea what may or may not have been later installed on any behicle since its build date...it is very odd that they make mention what earlier models had the 11 inch brakes and thus not interchange and to leave out any data pertaining to availability..that is what I am talking about..

55 Fargo Posted June 25, 2009 Report Posted June 25, 2009 1941 to 1948 Chrysler 6 cylinder, 11 inch brakes, 8 cylinder, 12 inch brakes. On my 1947 C38 6 cyl Chrysler, 11 inch brakes on rear, 10 inch brakes on front, why? The front end, brakes except steering box are from a 1951 Plymouth, so they are quite interchangeable, between the use of the 10 or 11 inch Mopar brakes,spindles etc. Should I get rid of my 10 inch front brakes, will they be inferior for my Chrysler which weighs about 600 lbs more than a P15? I will go to front disc next, will be easier for a kit with the 10 inch brake set-up,methinks.............Fred Quote
Young Ed Posted June 25, 2009 Report Posted June 25, 2009 Norm I believe my official POC judging guide doesn't mention a year for the switch to 15s. It is broken down as a before and after serial number xxxxxxx. Quote
Young Ed Posted June 25, 2009 Report Posted June 25, 2009 Right you really do have a 47 titled as a 48. Dads 50 ply is titled as a 49 because it was sold before 1-1-50. But there is no arguing that its a 50 model. Quote
Plymouthy Adams Posted June 25, 2009 Report Posted June 25, 2009 I just read not more than 30 minutes ago that Chrysler considered all cars built after 1 Jan to be considered production for that year..so instead of following a production year simialr to the way the government uses a fiscal year date, they use the calender year starting with 1 Jan now this is in direct reference to the P15 and the years 1945 (first made post war car) through the 1st series P15 that terminated at end of Feb 1949 am not sure if this practice continued with other models...

55 Fargo Posted June 25, 2009 Report Posted June 25, 2009 Wow Norm, that is quite a history, wish I knew my car's history. I am very surprised your car is in as good a shape body wise as she is, having driven through the Wisconsin winters for 25 years, is this possible, with all the salt, I would have thought it would be real rusty underneath. Shes's a real Survivor.... Quote
Plymouthy Adams Posted June 25, 2009 Report Posted June 25, 2009 another interesting note and the only one that I could find related to 10 inch vice 11 inch is the fact that commercial P15's (taxi cabs etc) were offered at additional price the option of having a 11 inch clutch over the stock 10 inch clutch..

BobT-47P15 Posted June 25, 2009 Report Posted June 25, 2009 (edited) Ed, I have noticed that "before" or "after" serial number thing in the parts manual. I guess if you could tell which year certain serial numbers related to, then you could say what year an item was used. Otherwise, you have some generalizations that - for example - a 47 Plymouth had 16" wheels and a 48 had 15 inch wheels. I wonder-----if you looked in the parts manual, would it identify reflectors as used by the parts numbers and could the dates be determined. Edited June 25, 2009 by BobT-47P15 Quote
Young Ed Posted June 25, 2009 Report Posted June 25, 2009 Finding a before and after serial number listing gave me brakes in my old truck way back when. Turned out that both the MC pushrod and the pedal changed after a certain serial # in 46. Well I had one of each and the combination made the pushrod way too short. Quote
Young Ed Posted June 25, 2009 Report Posted June 25, 2009 OK 15in wheels began with the following serial numbers detroit s deluxe 11851594 deluxe 15251917 Los Angeles S deluxe 25036148 deluxe 26010991 Evansville S deluxe 20234249 deluxe 22063548 Quote
Plymouthy Adams Posted June 25, 2009 Report Posted June 25, 2009 Norm said: Just realized the parts book was laying on the file cabinet behind me. Anyway' date=' according to the P15 parts manual, printed by Chrysler, on Page 192 it list two drum sizes (with different part numbers) for the P15 like I said. List both the 10" and 11" drums. So..........that's the official word on the subject. Guess we could have settled this a long time ago if I had just turned around in my chair. List the drums for both front and rear in both sizes.[/quote']scan me a copy Norm...my official parts books (Chrysler published three total) list only one part number... Quote
Plymouthy Adams Posted June 26, 2009 Report Posted June 26, 2009 I see it Norm and I am apologize for doubting you..this is the first source I have seen that shows this...thanks for posting the pic..have saved it to my P15 archives..never to old or ornery to learn.. Quote
