Until Shimano changed the design of their brake calipers and their brake levers’ cable pull ratio, every cable actuated road brake lever was compatible with every road brake caliper including cantilever brakes.
Shimano made this change when they went to their SLR-EV brake architecture. Rather than list out what Shimano group generations are made for SLR-EV, and which ones are for the traditional brakes, there is a very easy way to understand which levers work with each type of brake. If the shift cables go under the handlebar tape, the lever is made to work with SLR-EV brakes. If the shift cable is exposed coming out of the shifter, this lever is made for traditional brakes.
