34. How to Adjust V-Brakes
Learn how to adjust the brake pads, cable tension and centering on v-brakes (linear pull).
Today we’ll learn how to adjust v-brakes, which are otherwise known as linear pull brakes. For this job you’ll need a 5mm allen key, a phillips(+) screwdriver, a strip of sandpaper, and an optional cable puller.
The first step is to set up your brake levers. Start by loosening the clamp, and then align them so that they match the angle of your arms when you’re riding. Once the angle is set, tighten the clamp. If you have smaller hands and your levers are hard to reach, you can set them closer by tightening the reach adjustment screw on most levers.
Start by giving the cable some slack. Tighten the lever’s barrel adjuster in all the way. Then pull the protective rubber back and disconnect the brake cable’s quick release mechanism.
Then remove the pads. V-brake pads have two sets of positioning washers on each side of the brake arm. Be careful to watch how the washers are positioned so that you can re-install them correctly.
Inspect your pads. If they are worn past the indicator line, or have metal poking through the surface, you’ll need to replace them. If they look ok, use your sandpaper to re-surface both pads.
Now check your brake arm tension. The brake arms should have good spring tension, which makes them release when you let go of the brake lever. If there isn’t much tension, you may have to increase it on both sides. Undo both bolts one at a time, but don’t remove them completely.
You’ll notice a small piece of metal poking out the backside of the brake. This is the spring, and it slides into one of three holes on your frame or fork. Most brakes work fine in the middle hole. To increase your brake tension, move the spring into the top hole. To decrease the brake tension, move the spring into the bottom hole. Then tighten the mounting bolt.
Now re-install the brake pads, with the washers in the same order as they were before. Align the brake pads so the pad face is flat against the rim. V-brake pads are different from traditional pads in that they don’t require any toe-in. Both the front and rear of the pad should contact the rim at the same time. Because of this, v-brakes will sometimes squeak when applied. If you’ve re-surfaced the pads and they are still noisy, you may have to try a higher quality set of pads.
Take a look from the side to make sure the pad is in line with the rim’s brake surface, and not touching the tire or hanging off the bottom of the rim.
With the pads installed, check the brake arm position. Both arms should be facing straight up and down when the pads are contacting the rim. If they are too wide apart, or two close together, you may have to re-arrange the pad washers.
One set of washers is usually thicker than the other. To correct brakes arms that are too far apart, make sure the smallest set of washers are closest to the pads. To correct brakes arms that are too close together, make sure the largest set of washers are closest to the pads.
Now re-connect the cable and adjust the cable tension on the brake arm by pulling the cable through the pinch bolt and tightening. You’ll have to play with this adjustment until your brakes feel good. I like to have mine set so that the pads hit the rim when my lever is pulled about 1/4 of the way.
Make sure both pads now have equal clearance, and are not rubbing against the rim. Both pads should contact the rim at the same time. If not, you can adjust the centering by tightening or loosening the side adjustment screw with your screwdriver.
Anyone know the link that's out there for replacing the recessed nut studs on tektros top end sidepull brakes (I did it on the quartz) using tektros lower end sidepull nutted studs. Believe it was a YouTube vid.
Have a friend who wants to do something similar and the link to the video would be far easier than trying to word by word the conversion.... Read more >>
My 90's road bike is working but the brake to the right is loose a little bit (from the brake sleeve or what ever that's called) it's still braking but the cable is trying to come out. How do I fix that?... Read more >>
Simple one for you. I have an Azzurri Tigre which has the gear changers intergrated into the brake levers.
What is this system referred as?
Thanks in advance for the education.

On Wife's ~1970 Gitane Grand Sport Mixte, with Mafac Racer Brakes, at the handlebar brake lever (Safety Brake levers, by the way).....
At the point where the brake cable enters the brake lever, is a cream colored plastic nipple that mates the cable shield to the brake lever assembly.. Not adjustable, just an interface from cable shield to brake assembly.....
The brake assembly does not contain plastic covers, just aluminum metal.
One cracked earlier this year, and I bought two loose pieces that look like this type:

Did a search and didn't see any info on it... have any of you guys ever tried this tool ?
I like the tool... it even sets the proper toe in and adjustment. The only thing I find troubling about it, is the lip on the top of the tool keeps the pads from going high enough on the outside edge of the rim. The pads run closer to the inside edge near the spokes(see pic)(Is this the proper position for the shoes or should it be higher ?) Other than that, it seems to be a great tool.
What do you guys think about it ??... Read more >>
My original set of rear pads prematurely expired due to crooked wear on the outside pad. Upon closer inspection I see the piston extends at an angle, or crooked. This is not how the front brake extends (same model). Anyone know if opening the caliper to address this is possible? Thanks... Read more >>

Picked up some strong mtb(36h,dw) disc and rim brake compatible wheels for a great price. Was looking to convert my mtb from v-brake to disc(frame and fork have the mounts for disc brakes).
Been looking at some mechanical knockoff Avid BB5, BB7 disc brake kits that come with what is in the pic.
Anyone know anything about these? Will they work?
From what I can tell, they are just like the brand name stuff, just don't have the brand name branded on them.
Have not had any experience with disc brakes and I'm looking to try some out. If there is a better br... Read more >>
Bought some new wheels(36h, DW) for the MTB to replace the old beat up original wheels(32h) that my MTB came with. The original wheels had the machined V-brake rim surface for the brake shoes to rub on. The new set has a painted brake rim surface and the brake pads are leaving black marks on the rims. They also are making a lot of noise when braking(shoes have been toe'd in too).
Should I be using a different type brake shoe with the painted rims??
Thanks... Read more >>
Hello, I bought a bike the other day simply for getting from a to b. It was second hand with a back flat, no biggie. However the back breaks, when I pulled them they don't seem to spring back out for the wheel to turn, so I was fiddling about with it and made it a little better but then I noticed the break cable by the handle bars have come out of its mount, the wire is still in the lever but there is no tension.
Could someone help me with this? Tried looking on the Internet but can't see any clear videos or information about fixing it. thank you!... Read more >>
where can I get the best price and decent equipment for an XR200 front disc brake???All that is there is an old stretched cable and the disc. I am a golf course rider....... Read more >>
Fixing up a vintage Gitane and just tried putting new brake levers on the handlebars. I realized that the opening where the cable is supposed to come out of each lever doesn't match up with the hole in the handlebars. Is this going to be a major problem to find levers that will fit this particular handlebar? Should I just replace the handlebar? Any help would be appreciated!... Read more >>
I'm trying to fix up an older bike. The brake cant on the front tire, right side is way off. It's already destroyed the break pad. I need to figure out how to change the cant, or any new brake pads I install will be destroyed in similar fashion. How exactly do you do this?
