UPDATE: Firstly we've had a quite wet Fall and Winter so far. Not much riding and testing yet. B U T, very frustrated with the TRP HY/RD brakes...that's the 'G' version for this forum.
Converting the V2.0 to 11 speed was a piece of cake, I'm very happy with it, as shifting working smoothly, and much better than I expected. I thought this would be the more difficult part of my upgrade
H O W E V E R, the TRP HY/RD are problematic for me to even come close to a solution. As mentioned previously in this threat, I've setup mechanical BB7's, and various Shimano hydro brakes for past recumbent's and MTB's in past with out issues. I've read and researched TRP problems, it seems to be a mixed bag. The only thing I haven't done (yet) is re-bleed the brakes. That's coming soon.
The issues are:
1) 140 mm rotor rubs frame stay at the vary end of the radii (not a TRP problem), not the weld, but the round tube itself. Has anyone been able to get a 140mm rotor to work on a V2.0 or disc brakes for that matter? I filed about 1.5 mm away, but don't want to loose too much for obvious reasons. This gives .75mm 1mm of clearance...my opinion not enough to feel warm and fuzzy about. I tried a 2mm spacer, but felt that it was pushing the hub away from the brake mounts making centering pads more difficult.
2) The caliper (both front and rear) will not center itself on the rotor properly without dragging the pad(s) on the rotor. Following the instructions by simply pulling the brake lever with the bolts slightly loose will not do. There is something odd about this that I'm unable to put into words. I've also tried eyeballing it, this is the only way I can eliminates drag to a degree so the wheels spin ALMOST freely, but not happy.
3) The pull is extremely spongy (both front and rear), no firmness at all, will not lock up either, and about 3/4 power of my old 11k mile road caliper brakes with worn-out pads. I possibly have 100-200 miles on this setup, with a ton of tinkering in-between.
4) Now this is weird, and took me a long time to figure out. Rocking the bike back and forth with the front brake engaged produces a knocking/popping sound, as if something is loose. I thought the headset was loose, because that's what it felt like, a tiny bit of slop in the front end...so I took it apart twice, examining it. But no, come to find out it's coming from the brake/caliper/rotor because the brakes are not holding the rotor and there is a ever-so slight give from the pads to rotor (yes all rotor and caliper bolts are tight).
What's odd is the centering and spongy feeling problems are with both front and rear brakes. Both are brand new, purchased from eBay, new box, etc, making me think the brakes aren't or shouldn't be defective or needs bleeding??
Anyway, next step re-bleed. But I'm not sure how that will fix the problems.
