Got a buddy that runs quads and side by sides off road in a local club.The trails in the local area are usually a mixture of red clay and sand both quartz and silica.

The factory brake pads apparently last like a snowball in hell in these conditions and he's looking for an alternative.The factory pads are some sort of sintered graphite bronze which is very soft.

Years ago when three wheelers were still in fashion I used to make pads out of 932 bronze which held up quite well.I told him I could draw them up in CAD and have the local water jet shop cut them out,but thought I would run it past the forum to see if there is a better answer first.

These are what the ones he brought by look like,no idea what make/model they fit.It would be a dead simple part to produce,water jet them out and then run them past a carbide 6mm ball endmill to relieve the top.

Seems like if you get too tough, you'll just transfer the wear to the disc. I guess there may be a sweet-spot in there somewhere.

Agreed, maybe a better idea is grooves in the rotars so sand can be wiped into and out of the rotar, or brake wipers.. :P Little stiff brushes mounted to make contact with the disk brake (they will wear to only hit thing sticking outta the brake soon enough)
