I’m not sure what people mean by feel or modulation? If you mean the lever squidges once the pads are in contact with the rotor then the Hayes have plenty of that…I prefer a much firmer brake feel though, but from what I can tell everyone is going for that elusive feeling of lever squidginess to ‘improve’ feel and modulation (although I’m personally not convinced – once the pads are on the rotor, it doesn’t matter how much harder your pull the lever – once they are on they are on).
Sorry Dick I don’t agree. I know the term modulation is open to interprestation. A good example are some old deore’s I had with 160 rotors. V snatchy – either on or off really – obviously is you break harder then the force increases, more friction therefore slowing you down faster. So your term once they are on doesn’t matter how hard you pull on the lever is wrong. pad contact means just that contact, the harder your pull on the leaver….
Modulation is also dependant on the lineage of the piston stroke so if non-linear the lever with increase the piston travel further so the further increase in the lever goes the stronger the breaking force – thats my take on modulation FWIW
