Turned Drums Not Fitting

[TexasPilothouse]

So bottom line is I had the front brake drum turned  and it still doesn't fit over the new brake pads? Any help is appreciated! Didn't know if this would make a difference but does a 49 B-1-B and a 52 B-3 have the same size of brake drums and pads? Both are 1/2 tons. Thanks

Are all of the adjustments for the shoes all the way in?

Did you crack the bleeder valve and try to push the shoes further in?

Did you get new wheel cylinders and if so are you using new or old pushpins? Been reports of mismatch between piston depth and pin length.

All new wheel cylinders and new pins!

I know this sounds redounded but did you try to clamp the two shoes with a large clamp?  I know I use a tool I use for woodworking and it compressed the shoes with the force of the clamp.

I don't think they will go together any further!

I wonder if you have the right brake cyclinder? And here is a picture of what I used at one time as I remember???http://www.rockler.com/product.cfm?page=5334&utm_source=google&utm_medium=cpc&utm_term=&utm_content=pla&utm_campaign=PLA&gclid=CI6lyNij4rYCFct7QgodyxgAaQ

I'll try that before I go about ordering new brake cylinders again!

Are your lower brake hinge point adgustable. I think some work like a cam. they adjust in and out. ???? Are the  hinge pins in backwards??I think the nuts go to the inside.Can you put your new and old brake shoes side by side and see if there is a difference. Twist a coat hanger around your spindle and run it out to the shoes. ( poor boy brake caliper)Check if your brake   shoes are in a circle. ( checck for roundness)

If you still have the old shoes, compare the thickness of the new friction lining with the old linings. The photos suggest your fit is close,,,, but just a tiny bit too large.

You can putz around for hours trying to figure out what is wrong or just pull off a single shoe and see if it fits the inside circumference of the brake drum. If is does then you have an issue with either adjusters not fully retracted or wrong wheel cylinder pins. 

 

If it doesn't fit then then you have the wrong size shoes. Find a real brake shop and they can grind them to fit the drum or return for the correct sized shoe.

Check the part of your brake shoe that fits inside the wheel cylinder and see if they go all the way inside the cylinder.. Check and seee if they are hitting one side or the other  Maybe they are to fat to go all the way in.

I will try all of that and let you guys know how it comes out! Thanks for all the help!

Landon,

There are two different length 'close pins' (the piece between the shoe and the wheel cylinder.

Maybe you ended up with the long ones?

Different piston designs too.
