The specific method is as follows:

1. There are two kinds of brake pads for spinning bikes, one above the wheel and the other on both sides of the wheel. There is a compression spring on the brake pad. You just need to remove that screw and put it back. It's simple.

2. If only the brake pads are replaced, only one fixing bolt on the brake caliper can be removed. Remove the bolt, apply force to the brake caliper with a flat-head screwdriver, so that the brake cylinder piston automatically presses back, and then take out the brake pad.

3. You can also use the piston adjustment tool to press the piston of the brake cylinder back, and take out and insert the brake.
