Did I purchase the correct brakes for my Huffy bike?
Firstly you need to confirm the material of your wheel. If your wheels are carbon fiber, you need to use the professional brake pads made of cork which are normally labelled as "use for carbon rims".

If your wheels are aluiminium/alloy or steel, use pads made of rubber. 

Secondly you need to confirm the brake type of your wheels. The mountings for V brake pads and caliper brake pads are different.

Your photo shows pads for an older bike with caliper brakes.

Please take a picture of your brake and add it to the question.
