V brake installation steps

A Vbrake is called a V brake because the arms make a V when brought together.
It looks intimidating but if you really study it, the concept is quite clever and simplistic.

I laid out a standard side pull brake against the cabling for the V brake. Note the similarity in function.

The left arm has a swivel where the cable simply slips through it and gets held in place by tension on the cable. Nice quick release feature!

Here is the trickiest part of the assembly.  Start with the coil spring tab poking in the center hole.  Later if one of the brake arms doesn’t have enough tension you can adjust this up or down to get more or less pull from the arm.  The bolt tightens clear down against the frame which lets the brake arm swivel freely.

Once everything is assembled, you have to do some tweaking and re-adjustment.
Things to focus on:  Get the cable length the correct length to bring the brake pads close enough to the rim.  Adjust to your desired brake lever pressure.

Next you need to get the brake system to center itself. Make minor adjustments back and forth between the 2 arms using the small adjust screws.  If the adjuster screws don’t give you enough adjustment, you’ll have to remove a brake arm and move the spring to a different hole.

There is no right answer here, just lots of adjustment and re-adjustment.  With practice, the system will start to make sense and it’s MUCH easier than trying to do something like adjust the shifter mechanism on a mountain bike.

Re: V brake installation steps

Has anyone tried using a Tech77 on a vbrake? I read something about the brake levers for Vbrakes from Sheldon Brown's, very interesting stuff there. Seems like Vbrakes need a longer brake lever or something but it would be so ugly if you were to have 2 different brake levers on a handlebar. So my Haro Group 1 has a rear Vbrake and a front "i forgot what you call it" brake, i wanted to use both Tech77 (DiaCompe) on the handlebar so each time i stop with the rear brake, the rear wheel locks..i've just got to be real gentle with it. Think there's any solution to that? From what i read from Sheldon's it seems like there isn't.

Re: V brake installation steps

I agree with Ant, any lever will work because you can adjust the sensitivity of the pull by the length of the cable in back.

one thing to note, some levers have their own spring back mechanism. so if you couple that with the spring action of the brake you might not like the "weight" of the lever.

Re: V brake installation steps

vbrakes require long pull levers if you want working vbrakes. there may be some people in here that are used to the Sh!tty braking abilities of the caliper style brakes which suck at best and think if the pad rubs the rim you are good to go. shimano XTR levers and brakes are the way to go.

Re: V brake installation steps

hmm, well i like good braking, vbrakes and shorter levers.

the logic to this is simple:  when doing/practicing manualling i like the edge of the lever to just reach 2 fingers so it's easy to bump without letting go of the bar.

the actual lever is not long it just pulls more cable (long pull).
i only use one finger even on my trials bikes were excellent braking is a must.

here is an XTR Vbrake lever

Re: V brake installation steps

here is a normal lever and a vbrake notice that there is a smaller radius where the lever pivots on a standard lever.

Re: V brake installation steps

I see I am not the only one using Tektro brakes.

I just picked up a Tektro brake setup(identical to the one in the pic above) from my LBS. It cost me $25 for everything and they guys threw in some cable ends and sheathe caps. They came with instructions but were pretty easy to set up. Just took some adjusting to get them perfect. Now the thing stops on a dime. Damn near threw me off the bike thge first few times I used them and they are on the back! No more worn out shoes for me! Cool thing about V-brakes is that they are very straightforward and pretty easy to figure out. The only thing I used the instructions for was what hole to use on the stay post.
