Abstract
Official abstract text for this publication.
A brake pad retainer arrangement for holding a brake pad in position relative to a disc in a disc brake. The arrangement comprises an elongated retainer bracket arranged to extend transversely over the disc and the brake pad, wherein the retainer bracket is spring loaded to press against a rim portion of the brake pad. The retainer bracket is also arranged to engage the rim portion at an angle, thereby biasing the brake pad in a direction away from the disc.
First claim
Opening claim text (preview).
The invention claimed is: 1. A brake pad retainer arrangement for holding a brake pad in position relative to a disc in a disc brake, the arrangement comprising: a rigid, elongated retainer bracket attached to a disc brake housing and arranged to extend transversely over the disc and the brake pad, the retainer bracket comprising a tapered surface portion configured to engage a tapered surface of a rim portion of the brake pad at an angle, thereby biasing the brake pad in a direction away from the disc, the tapered surface portion of the retainer bracket similarly angled to the tapered surface of the rim portion, a helical spring arranged to load the retainer bracket to press against the rim portion of the brake pad, and a fastener extending through a first end of the retainer bracket and into the disc brake housing to hold the helical spring in position. 2. The brake pad retainer arrangement of claim 1 , wherein the angle is between 5-15 degrees. 3. The brake pad retainer arrangement of claim 1 , wherein the rim portion forms part of a back plate of the brake pad. 4. The brake pad retainer arrangement of claim 1 , wherein a middle portion of the elongated retainer bracket is formed to protrude from the disc brake to shield the disc brake from mechanical impact. 5. The brake pad retainer arrangement of claim 1 , wherein the disc brake is a single piston disc brake, or a dual piston disc brake. 6. The brake pad retainer arrangement of claim 1 , wherein the brake pad is an outer brake pad of the disc brake positioned at a wheel side of the disc brake. 7. A disc brake comprising the brake pad retainer arrangement of claim 1 . 8. A vehicle comprising the brake pad retainer arrangement of claim 1 . 9. The brake pad retainer arrangement of claim 1 , wherein the fastener is a set screw configured to adjust the load of the helical spring on the retainer bracket.
