You will need a pair of pliers, and a number 10 metric wrench or a hex wrench that fits the nut holding the cable. When its too tight I grab the cable about 1/8" away from the nut and hold it tight. Then I loosen the nut and allow the cable to slide through the nut stopping at the pliers. Still holding the pliers on the cable tighten the nut. Now you can spin the wheel and check for rubbing. If it rubs the rim repeat again. I do 1'8 at a time so I don't get too much slack.

How do I get my brakes to work again?

If the brakes shoes are that worn that the adjustment on the handlebar will not take up the cable slack, you will have to make the adjustment at the brake itself, or get new brake pads.
The wear limit of the rims themselves is usually only reached after several sets of brakes.
(Depends on how much sand gets into the brake shoes)

Rear brake not releasing

I'm assuming these are rim brakes and not disk brakes. A couple things can cause this, first check to make sure the wheel is true and the rim isn't rubbing on the brakes as it rotates. Next check that the brake pads are not hitting the tire when applied. If they are, then the brake pads need to be adjusted to contact only the rim. If they still aren't releasing then the brake cable could be corroded enough inside the brake cable housing that the spring in the brakes can't return it. drip a little bit of oil (TriFlow works great) on the cable where it enters and exits the housing and work the brakes. If this doesn't work then the brake calipers could have some corrosion on the canti-lever posts (assuming these are V type brakes common to a lot of mtn bikes), a little oil might get them moving again. If the bike is normally stored outside then most likely it's the cable corrosion.

Back hand brake rubs on pads cannot adjust basic hand brakes

If you can't adjust your brake position by using the adjustment screws you can loosen the wheel bolts and physically change the tires position to make it fit within the brakes. If that doesn't work take you bicycle into your local bike shop and have them check your rim alignment.

Replace and adjust brake pads

Is this disk or brake blocks like cantilever or vbrake. I have disks now b ut have never messed with them. If it is not disk then I would just say to make sure that the rear part of the pad hits the rim first. Fine tuning is done by adjusting the turn buckle where the cable goes into the lever. Set the brakes so that when you are pulling hard on the brakes, on dry pavement, set the brakes so that they only get tight enough to not quite lock up. And make sure you use both brakes at the same time. Not just one or the other. adjust the pads by putting one or two dimes between the pad and rim. There are also adjustment screws on the brake arms that control spring tension and in the end the alignment of tire between the brakes. You want the same space between pads and rim on both sides. If they squeal because you have been riding with poorly adjusted brakes take a file to the pads to level them out. Thy will grab better after this. Hope it helps

How do I adjust the brakes

This brake mechanism has a Lock/Adjuster nut which holds the brake arms together but it is also to adjust them too.....Just hold the brake unit with hand and break the nut loose....loose enough that you can move each brake pad arm seperately but not to loose.....Then squeeze the arms inward until the pads almost touch the rim then tighten back up...this action moves the pads closer to the rim to stop better faster.....Hope this helps..........Metalpoet..........

Next mountain bike replaced brake pads but to tight. wheel won't spin

Take the wheel off and look carefully to make sure the rim is not touching the pads, then straighten the wheel making sure it isn't rubbing the frame anywhere. You probably need to adjust the cables to restore the cable length lost while compensating for pad wear.

Front brake pads are not resting on the rim

Getting hand-brakes adjusted correctly is often a challenge, but they are adjustable with the right size wrenches. On the other hand, a front hand-brake on a child's one-speed bike is not necessary and is only on the bike to give it sales-appeal. If this is a one-speed bike, then it has a coaster brake (operated by pushing the pedals backwards). Actually the coaster brake is much safer than a front hand brake anyway. If the child applies the coaster brake too heavily, they will just skid. If they apply the front brake too heavily, they will go over the handlebars. If the hand brake is not interfering with the front wheel and is just not very effective, I would just leave it as-is. If the brakes rub on the tire, you should adjust them so they don't rub the tire.

When I apply my brakes almost nothing happens and it squeeks.. i have tried tightening and loosening them but nothing works.


Depending on what brakes are fitted (I'll assume V brakes or U brakes for now) here is a similar procedure for both:

On the brake itself, loosen the pinch bolt , move the arms of the brakes inwards, so the pads are 1-2mm from the rim, tighten the pinch bolt. If the pads are down to their wear indicator, replace them. If they are missing the rim, on the ouside of them they have an adjustment bolt, loosen, aim the pads at the rim and tighten.

Adjust the lever tension by spinning the adjustment screw. Get this right for your own preferenece.

An added tip, to get your brake pads working amazing for a week or so, get a cloth, some Coca Cola and wipe the rims. The acid in it, cleans the rims of oil/contaminants and the stickiness grips the pads :)

Vote for me when this works , thanks.

Rubber brake pad rubs on rim.

take a small or medium size cresent wrench put it on the brake pad holder slot (the metal piece that adjust them up and down)and slightly tweak them in at an angle.. the brake pads will now be at a slight V angle to the rim this should quiet it down..if there's no room to do this then you"ll have to loosen up the brake cable a little to expand it out..remember its spring loaded so have you hand hold it together and slowly relax you hand then tighten with the other, or theres one more way which is probably a lot easier...adjust the cable screw barrel down a few threads if you can then you"ll have the room needed to angle them in.
