How to fix brakes on a bike? Step-by-step guide
How to adjust V brake pads
V brakes
V-brakes are the most common type of bicycle brakes. They’re also called linear-pull brakes or direct-pull brakes. V-brakes consist of two brake pads that press against the sides of the wheel’s rim, slowing or stopping the bike.
Brake pads wear out over time and need to be replaced periodically. When they get too thin, they can no longer grip the rim properly and will need to be replaced. You’ll know it’s time to replace your brake pads when you hear squealing when you brake or if your brakes feel “spongy.”
Steps to adjust V brake pads
Check the brake pads
How to fix your brakes on a bike? Brake pad wear is one of the most common reasons for misalignment. If your brake pads are worn, they will not make proper contact with the rim and will need to be replaced.
Figure out where the brakes need adjusting by pulling the brake lever
Once your brakes are properly aligned, you should be able to pull the brake lever and have the pads make contact with the rim in a straight line. If your pads are not aligned, they will either make contact with the rim at an angle or not make contact with the rim at all.
Loosen the bolts holding the brake pads in place
Once you’ve identified the area that needs adjusting, you’ll need to loosen the bolts that hold the brake pads in place.
Do not remove the bolts completely, as you will need to be able to re-tighten them once you’ve made your adjustments.
Move your brake pads into the correct position
Now, you can adjust where your brakes sit on your wheel. You want to make sure that the pads are centered on the rim and that they’re not touching the tire.
Once you’ve got your brake pads in the right position, tighten the bolts back down.
Tighten your brake pad bolts back up
Once you’re happy with the placement of your pads, it’s time to tighten the bolts back up.
Make sure that you don’t overtighten the bolts, as this can damage your brake pads or cause them to come loose while you’re riding.
Test your brakes
After you’ve made your adjustments, it’s always a good idea to test your brakes before heading out on the road.

Make sure your bike is upside down
Part of the process of adjusting your brake rotor is to spin the wheel. You’ll want to do this with the bike upside down on a flat surface so the brake pads don’t touch anything.
Check the rotor’s alignment
If you look down your wheel, you should be able to see a small gap between the pads and the rotor. This gap is what allows the brake pads to move when you squeeze the brakes.
If this gap is too big, your brakes will feel “spongy” and won’t work as effectively. If the gap is too small, your brake pads will wear out quickly.
The ideal gap is about 1-2mm.
Next, loosen bolts that keeps the caliper in place
Once you’ve checked the alignment of the rotor, you’ll need to loosen the bolts that hold the caliper in place.
Do not remove these bolts completely, as you’ll need to be able to re-tighten them once you’ve made your adjustments.
Press the caliper together
Once the bolts are loosened, you can press the caliper together. This will make the pads move closer to the rotor and make the gap smaller.
Tighten bolts
Once you’re happy with the position of the pads, you can tighten the bolts back up. Make sure that you don’t overtighten these bolts, as this can damage your brake pads or cause them to come loose while you’re riding.
Test your brakes
After you’ve made your adjustments, it’s always a good idea to test your brakes before heading out on the road.
To do this, simply release the brake lever and squeeze it again. You should feel your brakes engage firmly. If they don’t, you’ll need to make further adjustments.
Next, we will have a look at common brake problems and how to fix them.
Guide to fix common brake problems
Brake pads are not engaging
If your brake pads are not making contact with the rotor, you’ll need to adjust them. First, check to see if the pads are properly aligned. If they’re not, loosen the bolts that hold them in place and move them until they’re centered on the rotor.
Once the pads are properly aligned, you can tighten the bolts back up. If the pads still aren’t making contact with the rotor, you may need to replace them.
Brake Squeal
Brake squeal is caused by a vibration between the brake pad and the rotor. This can be caused by several things, including:
Worn brake pads
If your brake pads are worn, they may not make firm contact with the rotor. This can cause them to vibrate and squeal. You’ll need to replace your brake pads if they’re worn.
Dirty or glazed pads
If your brake pads are dirty or glazed, they may not be able to grip the rotor properly. This can cause them to vibrate and squeal. To clean your brake pads, simply remove them from the caliper and scrub them with a degreaser. You can also sand them with fine-grit sandpaper to remove any glazing.
Bent rotors
If your rotors are bent, they may not make contact with the pads evenly. This can cause the pads to vibrate and squeal. You’ll need to replace your rotors if they’re bent.
Loose caliper bolts
If the bolts that hold your caliper in place are loose, the caliper may not be able to grip the rotor properly. This can cause the pads to vibrate and squeal. You’ll need to tighten the bolts if they’re loose.
Warped rotors
If your rotors are warped, they may not make contact with the pads evenly. This can cause the pads to vibrate and squeal. You’ll need to replace your rotors if they’re warped.
Brake Rub
Brake rub is caused by the brake pads rubbing against the rotors.
A misaligned wheel will appear to “wobble” when you are riding and is the most common cause of brake rub. This can be fixed by simply straightening out the wheel.
If your wheel is properly aligned and you are still experiencing brake rub, check the condition of your brake pads. If they are excessively worn or glazed, they may need to be replaced.
Another possible cause of brake rub is a bent rotor. If your rotor is bent, it will need to be replaced.
Finally, make sure that the bolts that hold your caliper in place are tight. If they are loose, the caliper will not be able to grip the rotor properly and will cause brake rub.
F.A.Q How to fix brakes on a bike?
Why is my bike brake not working?
There are a few possible reasons why your bike brake is not working. First, check to see if the pads are properly aligned. If they’re not, loosen the bolts that hold them in place and move them until they’re centered on the rotor.
How much does it cost to fix bike brakes?
The cost of fixing bike brakes will vary depending on the problem. If the pads need to be replaced, you can expect to pay around $20-$30 for a new set of pads. If the rotors need to be replaced, you can expect to pay around $50-$100 for a new set of rotors. Finally, if the caliper needs to be replaced, you can expect to pay around $100-$200 for a new caliper.
Is it easy to replace brakes on a bike?
Yes, it is relatively easy to replace brakes on a bike. You will need a few tools, including a wrench and a screwdriver. You will also need to purchase new pads and rotors if they are needed. The entire process should take around 30 minutes to an hour.
How do you fix kids bike brakes?
The process for fixing kids bike brakes is the same as for fixing adult bike brakes. First, check to see if the pads are properly aligned. If they’re not, loosen the bolts that hold them in place and move them until they’re centered on the rotor. You may also need to replace the pads if they’re excessively worn or glazed. Finally, make sure that the bolts that hold the caliper in place are tight.
