I've never been able to get good braking on my MTB. Finally gave in when I saw some cheap wiggle deals and bought new front and rear brakes. Gave the rotors a really good clean with isopropyl alcohol. Rear brake is still exactly the same, really weak, can't lock the rear . Is there anything else I can try or do I need to get new pads and rotors next?
