Rear Brake Shoes

Hi guys, I have to change out my rear shoes, they're pretty worn out. I looked through all the threads and never really saw any How-To's. Because I'm mechanically stupid, are there any step-by-steps out there (with pics are nice) anyone could point out.
Thanks again Mac

 

You're right about the lack of a How-To. It's on my list, but unfortunately, I had to replace both sets right after I got both bikes as they delaminated from sitting so long. This was before I found this site and started writing these how tos.



From memory (but without pictures)...

1. Put the bike up on the center stand.
2. Loosen and remove the trailing arm bolt and nut.
3. Loosen and remove the brake lever adjusting nut.
4. Rotate the rear hub so that you can remove the ajusting rod from brake lever barrel.
5. Remove your rear axle cotter pin and discard.
6. Loosen and remove the rear nut and washer.
7. Loosen the rear axle pinch bolt.
8. Slide out the rear axle.
9. Pull the rear wheel off the splined hub (towards the right).
10. Remove the rear wheel from the bike.
11. Remove the brake backing plate from the hub.
12. Remove the shoes and clean all surfaces with brake wash.
13. Grease all pivot and rub points with a suitable brake grease.
14. Reinstall the brake shoes and return springs.
15. Reassemble in the reverse order making sure to use a new cotter pin on the axle bolt.

I may have missed a step or two, but this should get you headed in the right direction. Also, I found that if you hook the shoes together by the return springs, you can roll them onto the cam and pivot bolt a lot easier. Also, make sure the cam is facing the right way around before you reassemble the hub.

Cheers,

 

Once again Gamuru you are a GODSEND. Thank you once more.
Cheers Mac

 

scuff up the brake drum with some emery cloth to brake up the glaze, this will help the new shoes seat in better
beware though, the new brakes may not work as well as the old ones for a while, the old shoes were worn to full contact with the drum and the new ones
need to get seated

 

A buddy of mine tells me that you should just remove the drum and have it turned by a suitable machine shop. That way the braking surface is clean and likely closer to the same shape as the new shoes. Same with rotors and new brake pads.

Opinions?

 

Take out the Brake Activating Rod and burnish it clean with a wire brush or a Coarse ScotchBrite Pad.

While its out ... clean-out the Bushing and lube it with Synthetic Waterproof grease.

Chamfer the leading edges of the Brake Pads to prevent the new Pads from squealing.

Vacuum the dust out of the Brake and Hub ... don't blow it out becauser Rear Brakes contain asbestos.

 

Don't fix it if it ain't broke! If the drum or rotor surface is in good condition, use the emery cloth! I wouldn't have it turned if I didn't have to. They can only be turned so many times and then must be replaced.

 

It's a little blurry, but check this out:

750 Brake Drum

Clean or turn?

 

Does the brake surface have grooves in it? It doesn't look like from the photo. I would try cleaning it up first using some fine emery cloth and perhaps a wire brush to remove the rough stuff. Once you have the dirt, grime, etc., removed from the braking surface, run your finger over it and see if it has any groves, if not or if they are light, I would go ahead and clean it. I would suggest that if you have any doubt about the wheel bearings, now is the time to replace them with new ones.
Hope this helps...........
