Abstract
Abstract A disc brake is disclosed for use on an automotive vehicle. A disc brake includes a rotor having a pair of opposed friction faces, a fixed support member mounted adjacent one face of the rotor, a member slidably mounted on the fixed support member and straddling the rotor, and a pair of friction elements which are engaged by the straddling member to urge the friction elements into braking engagement with the friction faces of the rotor when a brake actuation is effected. A releasable clip is secured to the straddling member and extends through the friction elements to retain the latter on the straddling member. One of the friction elements is located in a recess on the support member, and a lost motion connection is provided between this friction element and the releasable clip to permit relative movement between this friction element and the clip along the face of the rotor so that this friction element may be placed in the recess of the support member before the straddling member is fastened to the support member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
251 words
In a disc brake, a rotor having a pair of friction faces, a pair of friction elements, one of said elements being disposed adjacent each of said friction faces, a member straddling said rotor and engaging each of said friction elements for urging each of the latter into braking engagement with their corresponding friction faces when a brake application is effected, a fixed support member, means slidably mounting said straddling member on the support member for transverse relative movement with respect to the rotor, said straddling member having an opening exposing the edge of each of said friction elements whereby the latter may be removed from the straddling member in a direction radially outwardly with respect to the rotor, releasable means engaging each of said friction elements to retain them on the straddling member, said support member defining a recess, one of said friction elements being received within said recess, and a lost motion connection between said one friction element and said releasable means so that relative movement is permitted between the one friction element and the straddling member without release of the releasable means; said slidably mounting means including a groove in one of said members and a tongue projecting from the other member and received in said groove; said releasabLe means including first pin means, said lost motion connection including an elongated opening in said one friction element receiving said pin means, the width of said opening being wider than the length of said tongue received within said groove.
Claim 2
Dependent Claim
251 words
In a disc brake, a rotor having a pair of friction faces, a pair of friction elements, one of said elements being disposed adjacent each of said friction faces, a member straddling said rotor and engaging each of said friction elements for urging each of the latter into braking engagement with their corresponding friction faces when a brake application is effected, a fixed support member, means slidably mounting said straddling member on the support member for transverse relative movement with respect to the rotor, said straddling member having an opening exposing the edge of each of said friction elements whereby the latter may be removed from the straddling member in a direction radially outwardly with respect to the rotor, releasable means engaging each of said friction elements to retain them on the straddling member, said support member defining a recess, one of said friction elements being received within said recess, and a lost motion connection between said one friction element and said releasable means so that relative movement is permitted between the one friction element and the straddling member without release of the releasable means; said slidably mounting means including a groove in one of said members and a tongue projecting from the other member and received in said groove; said releasabLe means including first pin means, said lost motion connection including an elongated opening in said one friction element receiving said pin means, the width of said opening being wider than the length of said tongue received within said groove.
Claim 3
Dependent Claim
52 words
The invention of claim 1, said pin means being a bent wire clip having a pair of legs defining said pin means and a bridge portion connecting said legs, said legs extending through openings in each of said friction elements, and removable fastening means securing said bridge portion to said straddling member.
Claim 4
Dependent Claim
39 words
The invention of claim 1, said slidably mounting means further including pin means secured to said support member and slidably received by said straddling member, said tongue and groove connection preventing rotation of said straddling member about said pin.
Claim 5
Dependent Claim
354 words
In a disc brake, a rotor having a pair of friction faces, a pair of friction elements, one of said elements being disposed adjacent each of said friction faces, a member straddling said rotor and engaging each of said friction elements for urging each of the latter into braking engagement with their corresponding friction faces when a brake application is effected, a fixed support member, means slidably mounting said straddling member on the support member for transverse relative movement with respect to the rotor, said straddling member having an opening exposing the edge of each of said friction elements whereby the latter may be removed from the straddling member in a direction radially outwardly with respect to the rotor, releasable means engaging each of said friction elements to retain them on the straddling member, said support member defining a recess, one of said friction elements being received within said recess, and a lost motion connection between said one friction element and said releasable means so that relative movement is permitted between the one friction element and the straddling member without release of the releasable means; said support member including a pair of arms defining said recess therebetween for receiving said one friction element, the facing edges of said arms defining bearing surfaces cooperating with bearing surfaces on the edges of said one friction element to anchor said one friction element when a brake application is effected, the upper edge of said recess having an opening at least as long as the length of the widest part of said one friction element to permit removal of said friction element from said recess through said opening radially outwardly with respect to said rotor; said slidably mounting means including a groove in the side of one of said arms facing into said recess and a tongue projecting from said straddling member and received within said groove; said releasable means including first pin means, said lost motion connection including an elongated opening in said one friction element receiving said pin means, the length of said slot being wider than the length of said tongue received within said groove.
