    Now we’re going to describe you how to adjust brakes for different brake systems step by step!

    Caliper Brakes

    Step-1: First check the brake pads if they’re in a right position and maintain an equal distance from the rim or not. And to verify that you have to press the brake and identify whether the pads create pressure over each other. And to straight that eases the back bolt, make adjustments and slowly tighten it again.

    Step-2: Now you’ve to measure the distance of the pads from the rims. And that entirely depends on your preference of how you want the lever’s flexibility. Squeeze the calipers and adjust the bolts until it feels right to you.

    Step-3: Make sure not to adjust the lever in a way so that no space for releasing the tires can be found. Keep the gear downwards.

    Step-4: Now it’s time for aligning the pads. The pads should always be positioned with the braking track centrally. Pads touching the bike tires and lower than the braking surface must be avoided.

    Step-5: Finally, we have to make a barrel adjustment. Put out the pads by moving the barrel clockwise. Then do the anti-clockwise movement to remove the space. You can even adjust the cable stretch in this way.

    Disc Brakes

    Step-1: First you’ve to check the brakes and for that unlock the quick-release switch and check the wheels if they’re in the right position. Then partially unscrew the bolts so that you can bounce the caliper from side to side.

    Step-2: After adjusting the brake lever check if the wheels spin smoothly. If you feel that it’s still scratching, repeat the process a few times.

    Step-3: If step two doesn’t give you any satisfying result, then, the problem is on the rotor. Check the space on both sides of the rotor and adjust the bolts.


    Step-1: First check the spinning condition of the wheel and then loosen the brake cable to adjust the tension or rubbing.

    Step-2: Slowly release the grip from the hand and see if the pads are in a separated length from the rim. You can move the cable from its position by using your fingers.

    Step-3: Re-tighten the bolts of the brake cable and put pressure to see if the lever is comfortable to you.

    Step-4: Now it’s time for adjusting the pads with the rim. You can either force the brake higher to activate braking or simply pressurize on levers. As the pads are now in a distance position, put it back in the right place and see if it’s still crashing with the tires.

    Step-5: It’s natural for you to feel rubbing in only one side while the side is entirely OK! In that case, enhance the tension on the spring so that it makes a forceful situation for brake arms. After that, you can readjust the pads until it feels perfect on both of the sides.

    Hydraulic Brakes

    Step-1: Check the brake lever to ensure that it is sitting horizontally to the handlebar. If not, then use a wrench so fix the bolts in a way (rotate downwards) so that the lever and the handlebar don’t crash with each other.

    Step-2: Check the brake calipers to ensure that they are not crashing with the rotor. The rotation should be centered and if not adjust the bolts and check if the wheels are still scrubbing.

    Step-3: Move the lever and adjust the bolts firmly. Check the position of the parts and fix that.

    Final Words

    Brakes should be checked regularly, especially before long mountain rides. Because a malfunctioning brake can make your journey really dangerous and it’ll difficult for you to get any help. And make sure to do a test drive after every brake adjustment. Never try to use one type of changes for a different kind of bike. And if you feel that something is wrong and you are unable to make it right, take that to a bike shop. So that you can get confident about the performance of the brake and drive safely.
