How To Fix Stuck Bicycle Brakes
2
Make Sure That The Brake Pads Aren't Worn Down
Pads that are worn down significantly will stick
no matter how much you adjust them. If your brake
pads are less than 1/4-inch wide, then you need
to replace them.
3
Check For A Lip On The Brake Pad
Shave Down The Lip. If You Do Find That The Lip
Is Sticking Out Too Far, Shave It Down With A
Razor So That The Wheel Can Spin Smoothly. Be
Very Careful Not To Slice Off So Much That The
Brake Pads Won't Work!

Lubricate the lever pivots
These are the points upon which the individual
parts of your breaks pivot. Do not use lubricant
on brake pads, rotors, or rims. This might ruin
the pads and make it hard for you to stop your
bike!
5
Check the cables 
If your levers are fine and the pad isn't stuck
to the wheel somehow, then your cables form the
next likely problem area. You should be able to
fix your cables by hand without consulting a
mechanic.

Adjust The Cable Lengths To Increase Tension
7
Lubricate the cables
Get lubricant in an aerosol can with a tube.
Then, spray oil into the cable housing at the
ferrule the cap where the cable enters the
housing underneath the brake levers.
8
Remove The Tubing
If the cable is still stiff, try taking it out of
its plastic tubing. First, remove the clamp at
either the caliper or brake lever. Then, pull the
cable out the opposite end.

Bleed And Replace The Brake Fluid
This only applies to hydraulic brake systems. If
you have hydraulic brakes, then the fluid will
occasionally need to be bled and replaced.
10
Consult Your User's Manual For More Specific
Instructions
There are several kinds of hydraulic systems, and
each is a little bit different. Look to your
manual for step-by-step instructions. If you
can't access your manual, try to figure out
exactly what type of hydraulic system you have,
and then find online instructions for that
specific system.

Adjust the calipers
The calipers are the part of the bike that
actually squeeze the brake pads to the tire.
Here's how to adjust them

• Unscrew the brake pads, located on the inside of
  the brake calipers above your tires. 

• Adjust the brake so that it is 3 - 5
  mm from the rim.

• Tighten the brake pad. Spin the wheel in the
  air and test the brakes. Adjust further as
  needed.

Take Your Bike To A Mechanic
If all else fails, then it may be most efficient
to ask a professional to fix your brakes. Look
for a reputable bike shop or mechanic in your
area.
