these pads are pretty good for the riding I do which is basically just mx tracks. I haven't taken them in sand or mud or water or anything like that though so I'm not exactly sure how they work out in those situations.
IVE HAD SEVERAL BRANDS OF PADS BUT BRAKING TOPS IT WITH SMOOTH POSITIVE POWER OVER THE ROUGHEST TERRAIN AT ANY SPEED HOT OR COLD, IT CHANGES IT FROM "DO I HAVE ENOUGH BRAKE POWER" TO "DO I HAVE ENOUGH TIRE TRACTION"
I chose to replace my stock worn out brake pads with Braking CM44's because I have heard good things about Braking and the sintered metal pads are supposed to be the hot ticket for the mud and sand I often encounter. The Braking pads drop into place just as well as the stock ones. Once they had bedded in they provided great stopping power and no squeks. I buy them again.
I have a set of these on my bike and they work great. I matched them with a braking wave rotor and it is a very nice setup. The brake system stays cool even if you are a brake dragger like myself. The best replacement pads i have ever used!
