I just installed a set of new sram code Rs, front + rear, along with new 200mm centerline rotors. I installed everything according to sram's user+service+bleed manuals. I trimmed the rear hose and bled the rear with a sram bleed kit, and worked the syringes back and forth until there were absolutely no air bubbles.
A couple of weeks ago, I installed sram G2 Rs, but thought they didn't have much power. I did not trim or bleed those, reading that they come pre-bled from the factory. So I just mounted and zip tied for 1 ride. Wasn't impressed.
I purchased the G2 Rs because the Tektro's that came with my Vitus Sentier 29 were pretty horrible.
Subjectively, the Code Rs w/ new 200mm rotors don't seem to have even as much power as the G2 Rs with 180mm rotors, and those didn't seem to have even as much power as the stock brakes on my old Giant Sedona DX (also Tektros). So far, I've tried 4 sets of brakes and neither of the more expensive brakes (for me), the G2 Rs or Code Rs seem even as powerful as the stock Tektro's from my $450 hybrid Giant.
The most likely cause is probably user error and perhaps I installed something incorrectly. However, I was pretty meticulous about it and spent about 3 hours installing, trimming, and bleeding the Codes. It's possible I could have something set wrong as well.
I've read over and over the sram Codes are supposed to have a ton of stopping power. They seem pretty wimpy at the moment.
One theory, is that the piston spacer was still present while performing one of the last steps, which is to pump the lever a few times before removing the lever syringe. Also, I may have had too big a spacer in there (the bleed kit comes with 3 or 4 different sizes). This may have led to not enough fluid in the system when I replaced the bleed screw in the lever. However, the front brake also seems underpowered, which I did not bleed and installed as it came from the factory. There's quite a bit of travel in both levers before they start to bite, and I'd have to floor either one to get it to lock up, if it even could.
Based on your experience with sram (or maybe any) brakes, or specifically Code Rs, does this sound familiar to anyone? Does anyone see a point where I may have made a mistake? Suggestions/advice/things to check to increase power?
Thanks.
