An idyllic bike ride can quickly be ruined by squeaky bike brakes. Here’s a checklist of common squeaky brake culprits and how to fix them.

You Will Need

Clean rags
An oil-free cleaner
An Allen or socket wrench
A piece of cardboard
New Pads

Step 1: Clean the pads(弄干净刹车板)
Clean the brake pads and rims with a clean rag dampened with an oil-free cleaner, such as rubbing alcohol, to remove debris. You may need to remove the wheel for access.

Bike brakes may be cantilever, side-pull, or disk. Determine which type of brakes you have to learn how to best maintain them.

Step 2: Check alignment(检查是否在一条直线上)
Check the alignment of your brake pads. The brake pads should make contact only with the rim, not the tire, and the pads should not be able to slip under the rim.

Step 3: Adjust the brakes(调整刹车)
Adjust the brakes with a toe-in. Loosen the pads with an Allen or socket wrench and use a piece of cardboard to create a half-millimeter gap at the back of the pad. This angles the front of the brake pad to ensure that it hits the rim first.

Bike brake pads may be cartridge pads that easily slip out, or bolt-on pads that require loosening a bolt, spacers, and washers.

Step 4: Remove the old pads(换掉旧的刹车板)
Consider replacing the pads if nothing seems to eliminate the squeaking. Buy the appropriate cantilever, pull, or disk brake pad.

Step 5: Install new brake pads(装上新的刹车板)
Remove the bolt or pin holding the old pad in place and install the new pads. Align the new pads with the rim with a toe-in.

The first two-wheeled, working bicycle was developed by a German inventor in 1817.
