Cushman brake/clutch lining replacement?
I have a 1946 Series 50 with same engine as the 53 airborne. I am replacing the linings and am up to the point of the rivet installation. Anyone done that and have tips for me. Parts from Dennis Carpenter and no extra rivets with the kit. Thanks

Check out Hanson Rivets.They have all you need,Tools,rivets etc.With the right tool,it is fairly easy. On your brake linings,be sure to taper the leading edge.This helps with better contact for the whole shoe.

Re: Cushman brake/clutch lining replacement?
Someone posted about doing their GPW/MB brake Shoes last month, a search would show their excellent visual "how to".
If in doubt about your riveting capability, you could opt to apply a layer of glue (the proper epoxy) on 1st, then apply the rivets, then your assured no movement and a permanent fixing to the backing plate.

Re: Cushman brake/clutch lining replacement?
Nobody here seems to know that the linings are riveted to the drum, rather then to the shoes!
Are your linings pre-drilled with the holes and countersunk holes? I just use a drift of the right size, clamped in the vice, then hang the drum over it, and peen the rivet end with a small ball peen hammer. Also check the shoes for wear, they seem to wear more than the linings!! Had some shoes cast in the past, but think they are all gone now.

Re: Cushman brake/clutch lining replacement?
I worked it out pretty good. The linings had to be drilled and countersunk and my concern was keeping the rivet tight through them and the drum. I made this little tool that did that and did not damage the lining.
The end stayed right on the rivet and turning the couplings let me keep pressure on rivet from inside and not damage the lining. Setting the rivets after that was easy.

Re: Cushman brake/clutch lining replacement?
Had to make different tool for clutch lining same principle just a shorter piece. Ground all thread down until it only rested on rivet head and held it with pliers and turned coupler until tight. With high demand for this specialty work I will ramp up production facilities

Re: Cushman brake/clutch lining replacement?
Well it worked well. I have my scooter running and don't have body on it and road tested but it is on a stand I built and lining's are in place and everything staying put and doing what they are supposed to do. No issues with clutch or brakes.

Re: Cushman brake/clutch lining replacement?
Got it on the road last Sunday first time it ran in 17 years. I probably have 20 miles on it now just goofing around. No problems with clutch or braking so it does work

Re: Cushman brake/clutch lining replacement?
I estimate about 1,000 miles on scooter now. Picked up a long screw in rear tire probably debris from clean up after Hurricane Ian. The rear tires are a real pain to remove so am doing maintenance and the brake lining will be replaced. Glad I made this set up. Clutch lining seems pretty good.

Re: Cushman brake/clutch lining replacement?
Glad it worked out fine! I just got a friends Model 53 running, after a lengthy restoration, we had the linings glued/bonded in by a company, we'll see how it goes, first testrun in a couple of days. Will post some pictures later.
