I think that if I ever get my system totally figured out, the rear brakes will finally prove their value.
I can't skid the brakes no matter how hard I press the pedal.

It stops okay but isn't quite enough to make me consider them "excellent".

Same model, a bit lighter due to several parts missing but it has a front disc, rear drum system and it stops about the same.
