I recently built up a Specialized Sirrus from 1987 using Sensah Empire shifters (11 speed) for SRAM. I am using Tektro R741 brakes. While they work OK, they aren't awe inspiring. Front braking seems mostly acceptable when riding on the hoods but not as reassuring as when riding in the drops. I wonder sometimes if I was riding on the hoods and had to stop really, really fast if I could do so. The rear brake is pretty weak no matter what, and I know that's partly due to the much longer cable and housing. I have not replaced the pads yet, but I did use brand new Jagwire cables and housing. I do plan on switching to some better brake pads to see if I can increase my confidence in the brakes.
