Claims
- 1. A disc brake caliper assembly adapted for use with a brake disc secured to a wheel of an associated vehicle, said caliper assembly including:
- A. a pair of brake pad assemblies;
- B. a caliper member having axially spaced sidewalls adapted to be positioned on opposite sides of the brake disc and a backwall adapted to circumferentially encircle the periphery of the brake disc and having an opening therein between the ends of the caliper member of sufficient circumferential and axial extent to allow the brake pad assemblies to pass radially outwardly therethrough;
- C. at least one elongated fastener member adapted to slidably engage the brake pad assemblies and, position them between the sidewalls of the caliper member on opposite sides of the brake disc, and provide structural support for the sidewalls; and
- D. means on said spaced sidewalls receiving axially spaced portions of said fastener member and normally operative to preclude radial movement of said fastener member relative to said caliper member but operative in response to limited axial movement of said fastener member relative to said caliper member and while said fastener member remains slidably engaged with said brake pad assemblies to allow said fastener member to be moved, in assembly with the brake pad assemblies moving radially outwardly through the opening in the back wall of the caliper member.
- 2. A disc brake caliper assembly according to claim 1 wherein:
- C. there are two elongated fastener members;
- D. each fastener member comprises a washerhead bolt;
- E. said means on said spaced sidewalls include, for each bolt,
- (1) a bore in one sidewall receiving one portion of the associated bolt,
- (2) a slot in the other sidewall receiving another portion of that bolt and opening at the radially outer circumferential edge of that sidewall, and
- (3) a counterbore in the outer face of said other sidewall receiving the washerhead portion of that bolt;
- F. said limited axial movement comprises movement in a direction from said one sidewall toward said other sidewall and through a distance sufficient to withdraw said one portion of each bolt from the associated bore in said one sidewall; and
- G. the portions of said bolts adjacent the boltheads move radially outwardly through said slot as the remainder of said bolts, together with the brake pad assemblies carried thereby, move radially outwardly through the opening in the back wall of the caliper member.
- 3. A disc brake caliper assembly according to claim 2 wherein
- H. each said bore in said one sidewall is a throughbore passing said one portion of the associated bolt;
- I. each said one portion has a threaded section extending beyond the outer face of said one sidewall; and
- J. a nut threadably engages the threaded section of each bolt and cooperates with the shoulder of the counterbore in the outer face of the other sidewall to preclude axial movement of that bolt.
- 4. A disc brake caliper assembly according to claim 3 wherein said one sidewall is the inboard sidewall of said caliper member so that said limited axial movement is in an outboard direction and through a distance sufficient to withdraw the bolts from the bores in the inboard sidewall.
- 5. In a disk brake caliper assembly of the type including a pair of brake pad assemblies; a caliper member having axially spaced side walls adapted to be positioned on opposite sides of a brake disk secured to a wheel of an associated vehicle and a back wall adapted to circumferentially encircle the periphery of the brake disc and having an opening therein between the ends of the caliper member of sufficient circumferential and axial extent to allow the brake pad assemblies to pass radially outwardly therethrough; and means for releasably positioning the brake pad assemblies between the side walls of the caliper member on opposite sides of the brake disk: the improvement wherein said positioning means comprises
- (a) at least one axially disposed bolt adapted to pass slidably through and support the brake pad assemblies;
- (b) a bore in one side wall of said caliper member receiving one end of said bolt;
- (c) a generally radially extending slot in the other side wall of said caliper member receiving the other end of said bolt and opening at the radially outer circumferential edge of that side wall;
- (d) coacting interengaging means on said other side wall, adjacent said slot, and on said bolt, adjacent said other end thereof, operative to preclude radial movement of said bolt relative to said caliper member and provide structural support for said sidewalls but operative to disengage in response to axial movement of said bolt through a distance sufficient only to withdraw said one bolt end from said bore to release said bolt and allow said bolt to be moved in assembly with the brake pad assemblies supported thereby radially outwardly through said slot with said brake pad assemblies moving radially outwardly through the opening in the back wall of the caliper member.
- 6. A disc brake caliper assembly adapted for use with a brake disc secured to a wheel of an associated vehicle, said caliper assembly including:
- a pair of brake pad assemblies;
- a caliper member having axially spaced sidewalls adapted to be positioned on opposite sides of the brake disc and a back wall adapted to circumferentially encircle the periphery of the brake disc and having an opening therein between the ends of the caliper member of sufficient circumferential and axial extent to allow the brake pad assemblies to pass radially outwardly therethrough;
- a bore in one sidewall;
- a slot in the other sidewall opening at the radially outer circumferential edge of said other sidewall;
- a counterbore in the outer face of said other sidewall, said counterbore axially aligned with a portion of said slot and with said bore and having a diameter greater than the width of said slot;
- fastener means having an elongated portion and a head portion, said elongated portion received at one end by said bore and at the other end by said slot and slidably engaging the brake pad assemblies between said ends to position the assemblies between the sidewalls of the caliper member on opposite sides of the brake disc, and said head portion received by said counterbore to preclude radial movement of said elongated portion and moved axially from said counterbore in response to axial movement of said fastener a distance sufficient only to remove said fastener means from said bore for facilitating removal of said fastener means and said brake pads together.
- 7. The caliper assembly according to claim 6, wherein said fastener means includes means disposed at said one end of said elongated portion to secure said fastener means against axial movement relative to the caliper assembly.
- 8. The caliper assembly according to claim 7, wherein said means to secure comprise threaded means.
- 9. The caliper assembly according to claim 8, wherein said elongated member provides structural support for the spaced sidewalls.
- 10. The caliper assembly according to claim 6, wherein said one and includes a threaded portion extending through said bore and received by a threaded member.
- 11. The caliper assembly according to claim 10, wherein elongated member provides structural support for the spaced sidewalls.
