I was just wondering about disc brakes because I recently noticed that my disc brake pads are wearing unevenly in the rear. It's wearing more at the top of the pads than at the bottom. Is it still safe to use them or should I get new ones? Also, I predomintly use the rear brakes so the wear is twice as much in the back than the front. Is this normal? Thanks
The uneven wear is common. Most folks use the front brake more than the rear, but that's neither here nor there. Assuming the brakes are set up correctly I would not worry about what you described. Have fun riding.
