Pads: Koxx Browns Time used:1 month Rim used: Monty Grind: Yes but worn down medium. Ceraminc: No Brake used: Magura What is your opinion of a working brake: Locks the wheel completely. How do they compare to previous pads you have used: Alot better, compared to my plazmatic pads there amazing! Review: Well at first they were dull, but as i had been told it took a bit for them to wear in. As I rode them they gradually started to hold better and better. After about a week or so I took them off the bike and sanded off the layer of glaze on the brake pad, after that they were amazing, the bite was there, the hold was there. I can't fault them.
