Revolutionizing Disc Brake Servicing: Our Custom Rotor Turning Machine for Bike Shops!

[@boosted.]

I like the idea except for the dwell time the sanding disk has on the rotor when it changes direction , I would let it travel in one direction only and stop in a different location than where it started….I’ve done something similar using an old hub with the axel clamped vertical in my table vise, I would use my 2” air powered rotary sander and with moving it closer or farther away from the hub you control how fast the rotor turns. Then flip it over and repeat.

Yes, we just lift up the sanding pad during the dwell time to give it a better look. I like going both directions because it gives a cross hatch pattern to the rotor.

@@gograva Yes on the cross section or multi directional cross hatching….. I get the same results by using slightly more pressure on one side of the sanding disk, then do it again in the other direction by using slightly more pressure on the other side of the sanding disk… really helps the pads bed in….. Great build guys I wish I had one.

@@gograva A day of riding and whatever pattern you have is probably not visible anymore. Seems like an unecessary risk of introducing uneven sanding when all you really need is just a scuff to remove contaminations.

This is brilliant, great job guys.

[@gograva]

Thank You!

Just change the offset of the 2in and then you don't have that issue of going over the spoke.

I saw another Canadian or american youtuber doing this a few months ago, can't remember his name though

[@E-Ryders]

Nice

[@gograva]

Thanks

whats the price difference between having discs reconditioned and buy a new 1s

[@gograva]

We will provide the service when we change brakes since it literally takes us about 5 minutes. So, it's a competitive advantage not an up-charge.

Hi! Cool tool! But won't that stamp-anti-bend thing leave scratch marks on the rotor?

[@gograva]

The sandpaper scuffs up the rotor which is what we are looking for. The bottom piece doesn’t leave any marks

[@jackiegammon2065]

Discs for bikes are obviously so much thinner than motorized vehicles, do you measure the thickness of a rotor before providing this service? It seems that there are different thickness measurements for each brand, do you take into account that number and then decide whether to provide the service or not? The time to do this service may not be all that great, but you are adding time to your service simply by removing/installing the disc again on the hub.

[@gograva]

Yes, the rotor needs to be at least 1.9mm before we sand. Our sanding technique maybe removes .01mm on the rotor surface though. A rotor turn on a vehicle removes much more material than we do. I think the 10 minutes it takes to do this service is well worth it when doing the brakes. It provides much more value to the customer.
