Abstract
A disc brake assembly comprises an anchor bracket, a guide pin, a main damper, and an isolation damper. The anchor bracket has a bore. The guide pin is slidably supported in the bore and has a stem. The main damper is between the stem and an interior surface of the bore. The isolation damper is also between the stem and the interior surface. The isolation damper limits contact between the stem and the interior surface.
Claims17
A disc brake assembly comprising:
- an anchor bracket having at least one bore formed therein;
- a guide pin configured to be slidably supported in the bore and having a stem;
- at least one main damper configured to be disposed between the stem and an interior surface of the bore and configured to bias a portion of the stem against the interior surface of the bore depending upon brake loading on the disc brake assembly;
- and
- at least one secondary damper configured to be disposed between the stem and the interior surface, wherein the secondary damper is configured to limit a contact between the stem and the interior surface depending upon the brake loading on the disc brake assembly;
- wherein the secondary damper has a contact threshold and, when a brake loading exceeds the contact threshold, the secondary damper allows contact between the stem and the interior surface.

A disc brake assembly comprising:
- an anchor bracket having at least one bore formed therein;
- a guide pin configured to be slidably supported in the bore and having a stem;
- at least one main damper configured to be disposed between the stem and an interior surface of the bore and configured to bias a portion of the stem against the interior surface of the bore depending upon brake loading on the disc brake assembly;
- and
- at least one secondary damper configured to be disposed between the stem and the interior surface;
- wherein a clearance exists between the stem and the interior surface of the bore when there is no brake loading on the disc brake assembly and as brake loading increases, the secondary damper is compressed until the clearance is closed and a portion of the stem contacts the interior surface.
