Wow $30, that cheap, I have many a good brake tool that cost more then that.

I honda ball joint tool runs $170.00, I'd buy a $30 tool any day

My OTC caliper spreader costs that much....

I used a screw driver to change drum brakes front and rear on my 68 Dart back in the day. Popped my self in the face once doing that too, I don't recommend doing that. Buy the tool for that price...
