    I understand the concern, and I have it too. But I have yet to discover "the problem".

    After having topped-off and installed new gaskets I've had no issues. Riding road, gravel, and MTB-paths with my cyclocross bike.

    How many miles have you put on them since installing the new gaskets?

    When I installed the new gaskets I really thought that had fixed my problems, but 200 miles later they weren't adjusting to pad wear. When I replaced the front pads, the brakes wouldn't properly engage even after repeating all the tricks. TRP replaced my calipers under warranty. Now I'm curious to see if I just had a bad set or if others are following the same pattern.

    i've done plenty of hilly centuries and gravel and dirt rides with my Hy/Rds and have yet to have any problems. i'm 210# and have been using the cheapo shimano resin pads.

    It is more related to terrain than distance. I can go 100+ with no issues, but sketchy stuff can kill them in a hurry. In any event, I am doing the Dirty Kanza in a fee weeks and don't have the confidence in these brakes to ride them for the event. Maybe I will experiment more later as I do think they have a good feel when working.

    Around 110km on MTB singletrack and 340km on road. Still breaking nicely (no further adjustments yet, but front pads probably soon worn out) :-)

    That's encouraging.

    I've put about 200 miles on my HY/RD's since they sent me the replacement calipers, but it's been mostly on pavement on dry days. I think my original calipers went 600 miles or so in similar conditions before I started having problems.

    In fact, other than excessive lever pull (which isn't an issue with the new ones) I didn't really start having problems until it got cold and rainy. I probably won't have complete confidence in these brakes until I've worn through a set of pads and replaced them without any trouble.

    I've been using the newer Hy/rd with Ultegra 6800 levers(800km). Lever pull is perfect and they feel like true hydro system(Probably Shimano 11sp levers helped too). Unbelievable performance gain from Spyre calipers that they replaced.

    Why would you do that?

    I don't think the results would be good. The cable pull ratio would be all wrong.

    I just ordered a set of HY/RD and am a bit concerned about my decision. To those that had newer, working properly(?), versions of the HY/RD's. are there any visual differences between the two versions? I'd like to verify that I have the updated version prior to unboxing.

    Hopefully these are the ones they are sending me. Mine last pair were apparently the original crap ones. Less than 400 miles on the bike and TRP is replacing the brakes. Thankfully it is not my only bike.

    I didn't notice any visual difference between the ones that didn't work and the ones that worked for me. I was talking to one of the mechanics from Sellwood Cycle at a race this weekend and he seemed pretty confident that he's figured out the necessary tricks to make even the original models work.

    I will say that throughout my troubles with these brakes TRP tech support was very responsive and reasonably helpful. I could tell early on that they were still trying to figure out the problems themselves, but I think they understand it now. The new model will probably be reliable.

    I have an early set from last year.
    They now have around 4 thousand miles of dirt road rides and races and heading into their 2nd season of cross racing. Ridden in rain, mud and heat...with plenty of descending.

    The rear got the long lever throw early on. Added fluid and they have been fine.
    The stock pads are good....but I like the Shimano b01S pads a little better.
    I have run the EBC gold sintered pads in muddy races.

    I tried all the mechanical brakes....these were the best overall.
    But they aren't as good as the Shimano r785....but nothing is.

    I like the feel of HY/RD brakes than SRAM hydro. I've been using them since Dec. 2013 and they are just awesome. I wonder how well they will work in Canadian winter.

    Re: Anyone Here Using TRP HYRD's?

    Thanks all I purchased the Hy/Rds and they are really nice, easy setup and seem to work quite well, I've only got about 40 miles on them though.

The caliper from delivery #2 had long lever pull and vague engagement compared to #1. The top-off & purge procedure https://www.youtube.com/watch?v=S0i4aQ8S34w performed on #2 allowed a bubble to escape from the piston cylinder, which shortened lever travel and firmed-up feel a little.



    Note the use of a drinking straw like a pipette instead of syringe.

    I caution against adjusting the cable with barrel adjuster to the point the lock-out bolt is difficult to screw in; there should be minor drag, not resistance. If new cable & housing is installed with the caliper, re-adjust cable tautness after bed-in by screwing the barrel adjuster in, loosen pinch bolt, pull cable, tighten pinch bolt, and adjust using barrel adjuster. The latest barrel adjuster will only make 1.5 turns before spinning in place and that's not enough to accommodate housing bed-in on its own.

    SwissStop green (organic) pads perform well in my application.
    I would love to watch the video about topping off but apparently it is private, any chance you can fix that so I can see the process, I am about to have a second go at topping off my front brake and would like to see what you did first.

    I don't think you should have to do that anymore. Try contacting TRP support and see if they won't send you new calipers. As I understand it, the top off procedure was necessary because of some design flaw in the early runs of the Hy/Rds. I've never actually seen TRP say that directly, but they do seem to have stopped telling people how to do that and since they sent me replacement calipers (after a few rounds of working through problems with their support team) I haven't had any problems and have not needed to open the caliper for any reason. With my original calipers (purchased in June 2013), the top off procedure provided amazing initial results, but it turned out not to be a satisfactory long term fix.

    While I agree with Andy_K, there is also this video showing the topping off procedure: https://www.youtube.com/watch?v=LNaj5l8hUEY

    This is an old thready, but as an update to my original post, TRP was good enough to swap out my first generation HY/RD brakes with the newer model. I have not had any of the issues with fluid over heating that I had with the first generation brakes. They have been pretty well tested at this point, including a long technical single track descent that surely would have fried the old ones. I feel completely comfortable with the new brakes.

    I had a used pair of Hy/rd calipers on my bike, but took m off for a while.

    I always screwed up my pads. I thought it was the caliper leaking oil or something, but I read a German review that the B01S pads loose power when they got wet. That is also my experience. After putting them on and bedding them in, the pads and brakes work flawless. But after a ride in the rain or puddles, the brake gets a bit spongier and does not brake anymore. When I remove the pads, the surface looks very shine, like they are polished.

    When I was trying around with one of them, a piston fell out and oil seeped out too.

    My bike is always has to be outside. At home it is covered, but still exposed to moist air etc. At work its sitting outside exposed to sun, rain and everything in between.

    I have Avid G2CS rotors 200/160mm which I always clean with acetone when putting new pads on.

    Questions that I have now:
    -Which pads are good alternatives for the B01S pads?

    -Does anyone have the same experience/issues with the B01S pads?

    -Is there an alternative bleed kit that I could use? The original TRP one is quite pricey...

    Hoping for some answers here. I admit that during the time they work, I love them and I would really like to get them back on the bike.

    I have used SwissStop and Superstar Kevlar. The SwissStop have more 'bite" but costs quite a bit.

    You don't need any bleed kit, do the topping off procedure as in the above video.

    1. Remove pads
    2. Insert the bleed block: either use a Shimano bleed block (Y-8J712000) or make one yourself with bits of old plastic cards
    3. Level the caliper
    4. Wrap in paper to catch overflow
    5. Remove the top cap
    6. Pump the caliper
    7. Fill it up with Shimano/TRP mineral oil for brakes
    8. Put on rubber sea and top cap
    9. Clean with isopropyl alcohol


    If the old pads are contaminated and/or squealing and not braking well you can throw them out or try the following: Clean with isopropyl. Sand the brake pads. Heat/burn the brake pads with flame (cheap crme brl burner worked for me). Clean the discs with isopropyl. Sand the discs. Install and bed in the brake pads again.

    Shimano bleed block (cannot go all the way in, but works)

    Use isopropyl aclohol instead, it leaves less risidue.

    Hi tietze,

    Thanks a lot for your extensive reply. Will go through all the instructions over the next time. I just ordered swissstop organic pads, type disc 15 should fit.

    One question though just to be sure: One of my pistons once fell out (my fault), to refill them I really do NOT need a bleed kit??

    Thanks again, positive reputation given.

    No, just pump them to remove air bubbles, but be sure to put in a bleed block to get the right amount of mineral oil in and prevent it falling out again. Maybe some silicone grease on the sides of the piston.

    I've got them on my 2014 Diamondback Century. Set them up per the instructions. Broke them in (burned in) using the instructions on pinkbike and have had no issues. Rode all last season on them, no worries and no readjustments. May have the newer ones but that doesn't seem likely (based on age of bike). Rear is slightly softer than front but not problematic. My bike has the140mm discs and road tires, so not a apples to apples comparison perhaps.
    The most expensive bike in the world is still cheaper than the cheapest open heart surgery.
