|   Sluggish feel again!? (even with full-housing on V-brake) | PiroChu
Nov 14, 2002 10:59 AM | | Having read about going full-length cable-housing even on rear V-brakes through this forum, I did my convert back in early-October.
PiroChu "HELP: sluggish lever feel (Go full-length housing?)" 10/3/02 9:56pm
But, now the lever feels heavy & sluggish again. Why is that!?
The cable and the housing are still good and new (only 1.5mo),
and I only had 2-semi wet rides recently, but it's mostly dry here.
I often lube the pivot point on the SD-7 lever, some once in a while lube the moving parts on my Avid 2.5 rear brake, too, while always keeping things clean and all.
So, why did the sluggish feel already come back so quickly, especially after going full-housing? What's the next thing for me to take a closer look at?
(FYI, the other SD-7 lever hooked on my front Avid mech-disc still feels great since August.) |

Nov 14, 2002 1:48 PM | | Whenever my rear one starts feeling like that again, I just put some Tri-Flow in all the cable lining joints...such as the noodles and breaks in the lining. Gets them back to normal for a while, then it's time to lube again! |

Nov 15, 2002 9:33 AM | | Take the cable loose and check each part of the system to make sure it runs smoothly. It could be the brake arms, the cable, or the brake lever. The back brakes get gunked up really easily with all the water, mud, dust, etc. getting thrown on them. Could be the lube you are using, if it's oily it will attract dirt and gum things up, use lube very sparingly and use a dry lube such as tri-flo. |

| cable/housing/noodle are new & I use Tri-Flow on brake-lever/arm | PiroChu
Nov 15, 2002 10:26 AM | | Thanks, guys, for your feedback.
But, my cable/housing/noodle are new (only 1.5 month), per my post above, and I DO use Tri-Flow to lube my brake-lever pivot & brake-arms moving parts.
That's why this is puzzling. Any more ideas? |

Nov 15, 2002 11:02 AM | | the springs on the brake arms? Maybe increase the tension on those to provide a snappy return feel; but yeah, too much will require more hand pressure. Remember that there is also a spring in the lever that could be broken or out of position. Test by disconnecting the cable at the lever and making sure the lever snaps back. Are your pads contacting the rim nice and square? Toe-in is probably not necessary with the Avids; I like to set my pads so I can almost hear them slap against the rim with 100% immediate contact.
Hope something helps. |

Actually, my now-stiffer-feel rear brake/lever still has a good "snappy return" feel. It's just that it requires much more "hand pressure" than 1.5 month ago. Yes, I admit that my spring tension on the brake arms is on the low-side, because that's how I tried to much the lighter feel of my front Avid mech disc brake/lever feel. When I first put the new rear cable, etc on 1.5 month ago, it was pretty close to the front's feel. I'm afraid that, if I increase the tension in the brake arms, the already-stiffer-to-pull feel will only get heavier...
Hummm...  |
