Brake Pad Help Needed

[IrishG]

Hi,
I'm new to this forum and to go karts. I'm attempting to rebuild a go kart (I'm not sure the make, but faint writing appears to say Fox, it is a double seater). There is an existing brake caliper on it that says Thomas Ltd, I'm trying to track down a part number for replacement parts or expanded diagram. I think I may only need the brake pad (I have not taken apart the caliper yet, in case I'm left with spare parts - that should sum up my experience).

Can anyone let me know the brake pad type/specs/part number I need. If you know what I need is this the type of pad I can get at an auto/motorcycle store. I'm hoping I don't need to buy a new caliper.
I would appreciate any info anyone can provide.
Cheers

The brake caliper is a mechanical type- appears to be the same as the type sold at Northern tools.
