Braking that actually works.

Rim brakes are great, but they have an unfortunate penchant for not working well when it's wet, or when you don't squeeze them hard enough, or when a squirrel runs right out in front of you. Discs—we'll say it—are the future, and the Shimano RS785 Hydraulic Disc Brake Caliper is leading the charge. It's made to provide reliable, all-condition, fade-free stopping power when teamed up with Shimano's 11-speed ST-RS685 11-speed components, and features IceTech cooling fins, which are designed to dissipate heat, increase braking response, and keep performance high even during long, steep descents.

Suffering is over

  • Familiarity: I've used it several times

I have been suffering with pad to rotor rubbing since my s-works tarmac was new. Set caliper, bleed, reset pistons re-set calipers. After hard breaking rotor would rub for 10-20 sec. annoying but not the end of the world. Gave up on LBS a year ago. I finally realized inboard piston was sticking. Installed new caliper which includes pads (very cool) and wow silent front brake now. I wish I had done it sooner. I think Shimano has a problem with this part... (A friend’s 785 piston cracked, total failure)

Does this caliper have an external bleed valve nipple like the SLX/XT calipers or the integrated, hidden nipple in the body? A Google image search for RS785 caliper seems to show both types, but the external nipples are much easier to bleed.

Hidden bleed valve

Unanswered Question

Will these calipers work with Shimano ST-RS505 STI 11-speed shifters?

Are these brakes compatable with the ST 785 E shifter

I can answer myself, yes they do.

Does this come with the hydraulic hose?

This item does not come with the hydraulic hose.

Unanswered Question

What replacement pads work with these? The resin pads just wore out too fast for me (140 rotor and 1,500 miles with lots of tech single track). Stepping up to a 160.

Which shifter do I need to match these to?
