Brake shoe push rods

[mrbobs48]

I have a long push rod and a short push rod for the rear wheel brake cylinder. Which goes to primary shoe, and secondary shoe?

Here is what Im talking about for the 48 plymouth rear wheel cylinder push rod

They should be the same length.

Give us some history, how did you wind up with push rods of different lengths.

Is this what you discovered on dismantling your brakes, or some other thing?.......Fred

Took off both wheel cylinders and got some new ones. So I guess long ones are a set and the short ones are a set. My first brake job

Mr. Bob,

Ouch! you mean you took apart all your brakes?

I thought one should do one side at a time and if - if - having forgoten how to re-assemble, one could then go around the car and examine one that was still together as an example to jog ones memory to continue installing brake parts in the wheel they are working on. I have always found the best learned lessons in life are the hardest learned.

I'm sorry for your dilema and hope you have a service manual.

Good luck with your repair.

Just be mindful of new brake cylinders being slightly different cups or something along that line.

The pushrods have been known to be too long in some cases, where they are installed, then the drums cannot clear over the shoes.

Remember Drums can be machined out only .030 over factory size, this would bea measurement for example of 10.060, being the outer limit in most locales.

I have OEM cyls rebuilt, but I do know others have had similar problems with pushrods being to long.

I really think having your OEM cyls sleeved and rebuilt can be a good bet.

If your buying new cyls, go with the best quality you can get, Raybestos, seems to have a decent quality wheel cyl, so I have been told

I bought some wheel cylinders from O'Reilly Auto store a while back.

Some came with rods, some did not.

The new cylinders used a pointed end rod, the originals are rounded end.

The old style rod would not work in the new style cylinders.

Not sure now about the lengths of each.

Just something I ran into.

Ended up returning the new cylinders.

P.s. Looked in both my service manual and parts manual for the P15......those rods appear to all be the same

length. They all need to push equally.

Anybody know where to get new push rods? I have a '47 Desoto.

I just bought one for the front brake at NAPA. Cost $1.19 and can be easily reworked to fit. They are a bit to long for the front but might fit as is for the back brakes.
