Front Wheel Cylinders...

[Chiefrocka]

Hey guys ...

 

So I pulled apart my brakes to find my wheel cylinders where leaking, rusty, full of grime, and completely frozen.

 

I didn't pay attention to the what side they came off.  One side had a 1 3/8" x 1 1/4", and the other had a 1 3/8"x 1 3/8" 

 

I have the replacements one had, and I ordered an extra of the offset size.

 

I assuming the larger of the two would be on the pass side, because it is further from the master.

 

Anyone know ??

Replacements from Napa ....

I did notice that in the replacements, #3595 and #3596 ... the bore sizes would be facing the same direction.

 

Again, however on my '53...one side had a 1 3/8" bore...and the other side was staggered.

 

I just didn't pay attention when I disassembled.

 

 

thanks

The B-4 1953 Dodge truck shop manual says the front wheel cylinders are 1-3/8" straight bore for both front wheels. 1/2 thru 1 ton models.

That's interesting. I just looked in my parts catalog and I see that they changed to a straight bore front wheel cylinder with the B3's, at S/N 82267098. Before that they used the step bore cylinders, with the larger bore to the rear.

Interesting, and thanks guys !

Having to rebuild my wheel cylinders after 7 years of service, I completely forgot that I had stepped cylinders up front. Looking through my photos I came across these below which jogged my memory. The cylinders are marked L and R at the top. Interestingly though, the FSM lists only a straight bore 1-3/8" cylinder for the B, C, DU, EU, F, G, H, J, K models.

 

The PW models are listed with 1-1/4" front shoe and 1-3/8" rear shoe. The stock brakes have always worked excellent, I'm sticking with the step bore!

 

EDIT: Rebuild kit is NAPA part # 6.
