My new Trek Fuel EX from last year came with Avid Juicy 3.5 discs, and while the rear locks up fine, the front is just weak the first 5-10 min; initially takes 2-finger braking with only the front brake almost at max strength, going down ~20% grade. I've only ridden it under 50 or so miles (slacked off majorly since getting a job), so it's been sitting in the garage for months.
Below are pics of the pads and rotor. I'm wondering if it's "glazed"? It's seen rain and mud, so maybe oils got in? Also, the bottom pad (and top one, to a lesser extent) seems like only about half are in contact with the rotor, judging by the darker patch.
I'd like some feedback before trying sanding it and cleaning with alcohol. If new pads are required, do I need a new rotor?
