Title: Motorcycle brake disc on transaxle stub
Post by: Lee Barker on November 07, 2022, 10:59:36 am
Howdy--new to the forum; looking forward to access to the wealth of knowledge here.

I am building a parade vehicle from a riding mower. It's a great combo, because the mower is made for low speed and tight maneuverability. So max speed might be 25mph or so. I am building on a square tube frame I fabricated.

I do not intend to lock the rear end because I don't want to lose the maneuverability. So the brake:  Can I put an 8" disk on the tranny stub for a hydraulic setup? Seems that would be easier than two discs on the back axles.  BTW, I do have room on the axles for discs because I am using kart 4x4 hubs with trailer wheels and tires.

Thanks for your help. I can include pix if that would be helpful.

Use the disks on the axle. The reason being, if the chain inside breaks, you will have no brakes.
25 seems a little high, as most parades are barely a walking speed. I would try for 10 - 15 MPH in your gearing.
You can still go around a float, and put on a show.

It's been said "keep it simple" I believe it applies here also.
