Brake shoes

Post by glacoste » Mon Jun 08, 2020 3:00 pm

I've been working on sanding brake shoes using the hub and adhesive backed sandpaper. Let me tell ya... it's some fun! (sarcasm)
So if I can figure out how to resize my photos I'll be able to post them and be in business.
My question is.... Should I continue sanding until all the chalk in the photo is gone, or do you think it will suffice? It seems if I go any further I won't have enough meat on the shoe to last all that long.
What do you think?
Thanks

Check your brake cam.They are welded construction and lobes on my front twin leading shoe brake were crooked and lifting the shoe unevenly. This results in that tapered wear you see in the first photo. You might want to pull it out of final drive and eyeball it and true it up. I used a belt sander and just did it by eye. Still had a myriad of brake problems ie cable stretch, out of round drums,worn backplate and bushings.As Zorba would say "the full catastrophe". All are in the process of being improved that is ongoing for the past two years.

I've been working on sanding brake shoes using the hub and adhesive backed sandpaper.
If you enjoy 'sanding' have at it. If you just want to ride get a bit more aggressive with the process. Buy yourself a NEW single cut flat bastard mill file; 'new' ensures that it is sharp. Take off the high spots, and chalk up and finish with your sanding block.

You ARE wearing a dust mask; that wasn't a question.

I had my brake shoes relined with a woven material, they work much better than the OEM material. I had an extra pair I trade to a fella with front wheel drum brakes, he had to almost drag his feet to stop. He had messed around like you, with sanding an filling to no real benefit. He couldn't believe the difference with the new woven brakeshoe matterial. I think the reshoeing was about $70 a set. I put them on my drive and hack wheels and saw some improvement but not so remarkable (I think it's a flawed design issue), but I'm still happy with them.

When i replaced my front brake cable with one made by Kevin Macdonald of PT CUSTOMS front brake works great watched the video on measuring the darům and setting brake shoes evenly from center of axle as close as possible to drum size, also leaving shoes on drum plate and removing brake arms and linkage and spindles will go to lowest point, brake works real well, adjusted brake shoes on pusher and sidecar wheel having the pusher slightly dominate the sidecar brake to miminize right side pull
