By the way my cyclocross has Avid Shorty 4 brakes and the guy in the shop basically told me that they suck. I'm replacing the pads. He said that the Shimano brakes they had in the shop were even worse. Hopefully the new pads will get the brakes back to where they were at first.
A car pulled in front of me yesterday and my brakes didn't stop me at all and I took a big spill. Totally fine but definintely time to deal with this issue!
