    I now have one of those disc brake set ups on a trike I just purchased. Mine is installed wrong though. I may know where to get those brake pads. They are Hurst/ Airhart calipers which were used alot on the old chopper of the 70s as well as older go karts. I have to check a couple different spots, but those are the directions that you want to head in as far as looking for replacement pads. You may have to end up custom cutting some brake material and regluing them yourself or you may want to check with your local mom and pop auto parts store and see if anyone is offering service to redo old brake shoes. If they do, they should be able to reglue material to old brake pads as well.

    Mine is so hard to adjust. If you adjust it to where it should be, the rear brakes drag. If you loosen them so the brakes don't drag. It barely stops. There is quite a bit of pad there. It seems as though the caliper moves quite a bit when the brakes are on. They may be glazed..

    Are you ready for this?????

    I think we may be in business here!!!! Even though the caliper is slightly different, I think the pads may be the same. Or maybe you can write them and see if they have the pads or can make a run. Crazy eh?

    If you look under the "parts sheet" section, it lists all the parts to rebuild these calipers. Caliper mb 1!!!! Patting myself on the back for this.

    Well, If you buy the place out, save me a set of the rebuild parts and a set or 2 of the pads. I was just looking at my new trike in the living room and it's the same caliper set up, just with a different mount.

    You've seen it before. It's MyMints Ragin' Runt. I'm trying to figure out how to do pics with my new camera and I can't find on my computer how to link where the pics are stored with the new software to be posted on here. LOL

    Ok, Ok, save me some parts too! LOL I don't know if they have the brake discs to work with these as well or not, didn't really look into that. But hopefully the brake discs won't be too hard. Speaking of brake discs, I have to pm HondaHarry about some brake discs. Doh!
