Powerful braking.

After extensive testing, TRP brings an updated cable-actuated hydraulic braking system back to the cycling market with the HY/RD Cable-Actuated Hydraulic Disc Brake, offering you a cost effective way to achieve better braking power and modulation. First, you don’t need to spring for new shift levers (which is the case with many fully-hydraulic designs), because the HY/RD is compatible with all existing cable-actuated systems. The hydraulic mechanism is located at the caliper to keep your bars tidy. Also, braking is always consistent with HY/RD’s automatic pad wear adjustment, and with pads that are compatible with Shimano M525/M515 brakes, you have no trouble finding replacements. The calipers weigh less than 200 grams and are post mount with IS hardware included.

Fantastic option

Familiarity:
I've used it several times

I like the flexibility of hydro brakes but with the cables (for experimenting with bars, etc.). They work great so far after a few rides over the course of a few weeks. Also easy set-up. However, I'll note I think they skip a step in their instructions. Before attaching the cable, I clamped down on the caliper to center it and then tighten the bolts. Then I did the cable. Worked like a charm. I'll happily buy another set when needed.

Improvement over manual disk

Familiarity:
I've used it several times

I upgraded my Co-Motion tandem with these brakes. Installation was easy. Stopping power is a noticeable improvement over the cable only disk brakes. Side note - the tandem has a bracket in the rear that won't allow enough space for the HY/RD caliper so I could only replace the front brake. Even though, being on a tandem with total weight close to 340 lb. it's a huge improvement.
