I want to change the pads on the disk brake on my bike, but can't find the model number. All I know is that it is a Promax disk brake.How do you know what model number disk brake your bike has?
Go to the Promax web site and match the pads.

Go to the shop where you bought the bike and let them exchange the pads, it is not simple and if you do it wrong it is unsafe.
