JMHO,but not a fan of hydro rim brakes. Because the pads are thicker than disc pads,the pistons have to travel further,esp when the pads are worn. This exposes them to more dirt/corrosion,and leads to the seals getting torn up. If you insist on hydros,def make sure to keep them clean,or you're in for a rebuild.
