v brakes with extra tension

hi , could anyone recommend a set of v brakes with lots of tension , i feel like v brakes suffer from a lack of spring to return them back to a cleared position from the wheel , maybe i just use cheap ones ???

Typically that is due to cable binding from a corroded housing or cable, the return spring in the handle might also be rusted or gone. Proper adjustment balancing will also help. Last, remove the brake arms from the bosses and check for rust there as well, clean it and the inside ring with steel wool and apply a light coat of oil.

I somewhat disagree with Joe. I end up playing with the spring tension (either with the spring peg in which hole, by bending the spring and/or by respacing the pads to change the amount of arm travel) on many repairs. Some of these repairs had gotten new cables. By the point I am centering the brakes or setting the lever pull amount the cables are freely moving.

I attribute this to Shimano's pursuit of less lever pulling effort, by the rider, as their goal. Most all the other manufacturers follow the Big S like lemmings. Combine low tension springs with designs that have little range of travel (when tensioned) and poor rim width and pivot boss locations and sometimes it seems like there's barely any spring tension at all and the lever rattles in it's body from a lax cable.

+1.. Back bend the spring wire .. that increases the return spring force..



Best V brake I've used is Magura's HS33, German, Hydraulic rim brakes..

shimano parallel push suffered from too many pivot pins that wore sloppy

by using a piston that was better...

Andrew, I agree with you that the spring could be re-bent to increase tension

Also check the brake pads. Not uncommon for them to wear far enough they develop a lip that catches the rim and prevent them from returning. Happens with rims that have a central wear indicator groove too, the raised lip will be in the center of the pad instead.

As an official Magura Cult Member (got the official top cap of membership) I applaud your use of 33 canti brakes (not really V brakes though right...but V brakes are just long armed cantis...whatever). I've long since sold my last set of 33s though I do have some 11s. I REALLY used to love my 66s. I should have never sold them.

ok i understand all the adjustment techniques i can do , but was really just wondering what v brakes come with extra springy spings , its a silly commute porject so i have bar end TT brakes , i know the pull might not be accurate but im just working this thing out , this is my first silly bike build , a silly bike being a bike made from parts i found all over the internet ...

In addition to checking for binding due to corrosion on the pivots or buildup in the noodle, check your brake housing length so it's not pulling (or pushing) the arm to one side.

you might try to find discontinued TRP direct pull the full 10cm, long arms

, later for CX they made a shorter version now with an 8.4cm arm for road brifter ..cable pull
