TRP Tech Talks - HY/RD Bleed, Service, and Setup

In this edition of TRP Tech Talk, Dave breaks down the infamous HY/RD. He will show you some common trouble shootings, adjusting the brake to recommended settings, a full bleed procedure, and how to set the HY/RD up on your bike.

This was one of the best technical videos I've ever seen, in any industry! Excellent job, no hype, well thought out and arranged in order of importance, and addressing clearly every critical aspect of your product. Thank you.

This was an awesome video. Saved me a fortune in repairs. Very clear and thorough. I didn't have a clue about hydraulic brakes before, feels like a real achievement to have fixed mine myself!

This helps me out a lot with my hy/rd brakes, I'm a big fan of TRP products and have spyre and hy/rd on all of my bikes.

Super-helpful. I'm setting up two sets on my daughters' commuter/gravel/cross bikes, and I may put a set on my Straggler, too. Thanks for making well-thought out products and providing great support!

10:13 is where you were looking for tensioning the cable and setup a shorter pull on the lever

[chrissanders]

Top Job, even i managed to follow this and my front brake is now super sharp!

This video was very helpful. This is a much needed update from the previous bleed video on youtube and came at just the right time for me. I found the lever purge to be particularly useful and got a lot of extra air out the system by rotating the caliper. I was bleeding the caliper as after 4 years of regular use I thought the caliper was at the ends of its life. This bleed has helped but the performance is still not what I would like. Would TRP consider making a video showing how the caliper can be further serviced possibly examining replacing seals etc. You can buy lots of small part from the TRP website for this caliper. It would be nice to see how to use them. Perhaps I could gain extra performance this way.

Hey TRP guys..."lazy pistons" is a common issue on ALL hydraulic brakes...so would you kindly make a piston clean up and service for TRP Hy/Rd? That would be a great help for us TRP HY/RD users! 😀

[pierricjoseph]

Very helpful vidéo, thanks tout very much ! A useful addition (maybe just above the vidéo) could be that two M6 connectors are needed.

[bertrandc]

Merci pour le tutoriel qui est nécessaire pour faire proprement la purge de ce frein et son réglage. Bonne explication 👍

[Al_Fresco]

This is a great video, the only issue is that the Hy/Rd brakes I have seem to be slightly different and I can't tell where I should be pumping fluid into/out of?! I bought them in 2022 so I would have thought they're the latest model?
Manuals don't seem to show the updated calipers either.
Please advise

Kindly post an elaborate video on how to bleed the Hylex RS model as there are no tutorials on YouTube.

Excellent tech video, well presented and very easy to follow 👍🏻

[hauntyoo]

These are great brakes, the only cons are the weight, and the fact that you have to take the whole brake out so you can change the pads.

[jeppehedegaard]

Would you recommend to take it of the bike to bleed it?

[CircleOfSignfighters]

Hey TRP guys, quick question: is the barrel adjuster threading M6 or M7? I bought a set off ebay missing the barrel adjusters and scuttlebut is M6, but it'd be great to have confirmation from y'all directly. Thanks!

Dear Dave and TRP Team. I have bought a Triban RC520 which comes wíth Hy-Road PostMount 160 Rotor break system. No matter what I do how I set, adjust, clean and make anything on against my best knowledge and many videos on youtube, one side of the pistons still wont set back. It is just simply does not retract back to its place. There is 0mm distance between my disc and the break pad reagardless how many times I re-set the piston. For a year now and countless of hours of trials on adjusments, my front break drags and breaks all the time. It drives me crazy as my wheel wont spin a 1/4 round without stopping by the dragging-sloppy break pad/piston.

Could you please help me somehow? Do I need to purchase a new front-set eventually? :(

[oliveraidoo]

Hi, thank you very much for your advice. I very much appreciate it.

[fabolous]

Hi thanks so much for the great video? Im desperately looking for a bleed kit here in Germany. Could guide me to where I can find one?

[BRAK]

Good Video. Would be perfect video if you shows how far the pistons can be pushed out (for cleaning reason) before they pop out...
Or where are the cleaning - maintains videos.
Thank you.
