I finally got to working on the brakes. I dismounted the bracket that holds the brake strap but I can't figure out how to dissemble it further. Looking through the port hole there appears to be some kind of pin holding the brake lever in, but it doesn't move. ON the flip side of the bracket is another port hole, but it doesn't look like the pin goes the entire way through. I think I have to take this apart and get a new brake strap.

 

btw...where is the best place to get new brake straps? 

 

Anyone gone through this? Thanks for the help!!!!!

 

Thanks!

I've only torn mine down as far as you but I'm thinking those might be a tapered pin . Wonder if the parts manual would say if they were ? Your drums look really rusty will you be able to sand them smooth ? Couldn't see what your lining looks like but years ago when PK was still selling tractors had dealers I went to one looking to get new brake bands for my Jim Dandy , he told me as long as the lining was thick enough to just use sandpaper and brakeclean .

I just went through this on my '56 PK. One side had a solid pin, and the other side had a hollow roll pin. The roll pin was most likely a replacement. The hole does not seem to be tapered. I had to use heat to get the pins out, though. It looks like you have the 4" drums, and the band's are usually available on Ebay. My drums were worn thin, so I had to replace them.

Thanks Gents, 

 

I think I should be able to sand the drum, I don't think it has to be perfectly smooth I'll try the heat trick and see if I can get that pin out.

Well it took about 3 hours of heating, tapping with a hammer, and lube...but it finally came apart. 

 

No pads on ebay right now, but Ill keep an eye out. 

 

Thanks Again

Would you sand and paint the parts before putting them back together? Will the paint make any real difference against corrosion?

Hi yes I would paint most of it maybe just primer on the parts that fit together as they may not go other wise and you'll end up removing the paint, if you want McMaster Carr has brake lining material or Mission Mfg would have them

Glad to see that you got the assemblies apart. I had to buy new bands since one was rusted in half, and the other was badly corroded and about to break. Relining your bands would be my choice. Paint as MNGB said. Bare metal rusts up quick, especially after you put heat to it.

Thanks for the help . I ended up needing new bands . I got it painted and resembled ... Now off to do the other side . I was not able to move the adjustment heads on the rods that connect the brake pedals to the breaks even with heat . The vise grips just shred the metal and they don't budge . Thinking about trying to gently cut the heads off of the threads and buy new ones ... Anyone try that before?
