Re: Porterfield kevlar rear shoes?
Kevlar is one of the most aggressive and hardest brake material available. It hardly wares at all, in fact depending on the formulation, you will likely see the drum wear away instead of the shoes. Kevlar on brake shoes is often very sticky and can be notorious for causing premature brake lock up. It dusts heavily and must be clean out often.
I would avoid them.
