[0053] According to a first embodiment, when the disc brake rotor 8 is removed from the brake disc groove 18, the spacer 16 is configured to move from the first position to the second position under the manual influence M of the user. This allows the user to decide whether to keep the spacer 16 in the first position, outside the brake disc groove 18, or place the spacer 16 in the second position, between the first and second brake pads 14a and 14b of space 20. The spacer 16 is configured to move from the first position to the second position by a force applied by the user that overcomes the resistance of the snap fit engagement structure 36 . Conversely, if the spacer 16 is in the second position and the disc brake rotor 8 is inserted into the brake disc groove 18, the resistance of the snap fit engagement structure 36 when inserting the disc brake rotor 8 must be overcome by User-applied force overcomes. During insertion, the disc brake rotor 8 contacts the spacer 16 and a ...

Abstract

The present invention provides a bicycle disc brake caliper, which may include: a caliper body having a brake disc groove configured to at least partially accommodate a disc brake rotor removably disposed therein; one and second brake pads movably disposed relative to each other in the brake disc groove for contacting a disc brake rotor disposed at least partially in the space between the first and second brake pads; and a spacer movably attached to the body of the caliper. The spacer may be configured to be positioned in a first position outside said space when the disc brake rotor is disposed in the brake disc groove, and the spacer may be configured to be positioned when the disc brake When the rotor is removed from the brake disc groove, the spacer moves from a first position to a second position in which the spacer is positioned in said space.

Description

Background technique [0001] A typical disc brake caliper for a bicycle wheel includes a caliper housing, one or more pistons, and two brake pads. Brake pads are positioned on either side of the rotor. Upon actuation of the brake device, the one or more pistons are configured to cause the brake pads to contact the rotor, thereby applying frictional resistance and slowing or stopping the bicycle. When the rotor is not present between the two brake pads, accidental actuation of the brake device can cause the brake pads to stick to each other. In some use cases, such as during the course of a bicycle road race, participants change their wheels frequently. When a participant replaces a wheel with a built-in disc rotor and the participant accidentally operates the brake lever while the wheel and disc rotor are being removed from the disc brake caliper, braking after the participant releases the brake lever The pad will not return to its original position. This complication can d...
