Spot type disc brake including an improved hold down spring
First Claim
1. Spot-type disc brake comprisingfirst and second brake pads which are adapted to be pressed against respective opposite sides of a brake disc,a caliper which engages over said pads and said brake discs, anda hold-down spring of sheet metal supported by a support region formed thereon near said first brake pads on the caliper and extending from said support region in cantilever manner beyond said brake disc, wherein the hold-down spring comprises first, second and third spring legs extending parallel to the axis of said disc, said first and second spring legs being separated from each other by a first axial slot and in the relaxed state lie at least approximately in a common plane and extend beyond said brake disc,said first spring leg having a portion remote from the support region which portion pressing against said second brake pad,said second spring leg being separated by a second axial slot from said third spring leg in such a manner that the second and the third spring legs are joined only at their ends remote from said support region without being bent with respect to each other,said third spring leg pressing with its end near said support region against said first brake pad, said first and second axial slots extending parallel to the axis said disc.

Abstract
On the caliper (10) of a spot-type disc brake a hold-down spring (40) of sheet metal is supported with a supporting region (42) formed thereon near a brake pad (28); from there it extends in cantilever manner beyond the brake disc (18). The hold-down spring (40) comprises two pairs of spring legs (50, 52) which are separated from each other by a first pair of axial slots (60) and in the relaxed state lie at least approximately in a common plane and extend beyond the brake disc (18). A first pair of the spring legs (50) presses against the brake pad (34) remote from the support region (42). A second pair of the spring legs (52) is separated by a second pair of axial slots (64) from a third spring leg (54) in such a manner that the second pair (52) and the third spring leg (54) are joined only at their ends remote from the support region (42) without being bent over. The third spring leg (54) presses with its other end onto the brake pad (28) adjacent the support region (42).
