|   Salsa brake boosters | Ripzalot
Nov 22, 2002 7:35 AM | | I'm having trouble visualizing how these brake boosters work. Anyone have a pic (or a very nice description) on how they attach/work with your brakes?
Also, is it practical to have a mech disc in the front and v-brakes with a booster in the back? Unfortunately, my rear is not disc compatible.
Thanks............................. |

Nov 22, 2002 1:50 PM | | Basically they reduces frame / fork flex, which therefore increases the braking force applied to the rim. (which would lose if you didn't have the brake booster)
The brake booster is mounted on top of your V-brake, using the same brake bosses / studs. When you buy a brake booster they'll give you longer mounting bolts and spacers for your brake bosses.
In your case, if you squeeze the rear brake levers hard enough, you might see the rear brake bosses / studs move outwards ever so slightly. That's the Frame flexing and is your wasted braking power, so basically the brake booster reinforces the brake bosses / studs to reduce that flex.
Hope that helps |

Nov 22, 2002 5:34 PM | | the brake booster is horseshoe shaped (look them up at cambriabike or jensonusa.com) and each of the ends of the horseshoe bolt onto one of the ends of the brake bosses. (the posts your brake calipers pivot on) Since V brakes normally have enogh leverage that they push off of the rim, forcing the brake bosses outwards, flexing the frame or fork. The purpose of bolting the horseshoe on is to keep the posts from being pushed outwards, so that the pressure applied to the brakes isn't wasted on flexing the frame... it's all held to the rim, where it belongs. THAT'S what the booster does. Essentially, it really isn't a "booster," since it doesn't boost anything. It just keeps the frame or fork from flexing so that the force you do apply ot the brakes all goes where it's supposed to... the rim. |

Nov 26, 2002 4:11 PM | | I personally run an 8" Hayes mech disc front and a Salsa-boosted LX-V rear on my Giant ATX-890. It works great, the Hayes does most of the work anyway, and the booster definitely helps prevent flexing and feels much more solid. I've been really happy with that setup, give it a go. |
