Abstract
An opposed piston disc brake caliper adapted for use with a disc brake assembly includes a caliper of a one piece construction including an inboard leg and an outboard leg connected together by a bridge portion. The inboard leg has at least one piston bore formed therein, the outboard leg has at least one piston bore formed therein, the inboard leg has at least one generally axially extending opening formed therein which is coaxially aligned with the outboard leg piston bore, and the outboard leg has at least one generally axially extending opening formed therein which is coaxially aligned with the inboard leg piston bore.
Claims28
An opposed piston brake caliper adapted for use in a vehicle disc brake assembly comprising:
- an integral one-piece opposed piston brake caliper defining an axis and including an inboard leg and an outboard leg connected together by a bridge portion, said inboard leg having at least one piston bore formed therein, said outboard leg having at least one piston bore formed therein, said inboard leg having at least one generally axially extending opening formed therein which is coaxially aligned with said outboard leg piston bore, and said outboard leg having at least one generally axially extending opening formed therein which is coaxially aligned with said inboard leg piston bore.
An opposed piston brake caliper adapted for use in a vehicle disc brake assembly comprising:
- an integral one-piece opposed piston brake caliper including an inboard leg and an outboard leg connected together by a bridge portion, said inboard leg having at least one piston bore formed therein, said outboard leg having at least one piston bore formed therein, said inboard leg having at least one generally axially extending opening formed therein, said outboard leg having at least one generally axially extending opening formed therein, wherein said piston bores are staggered with respect to each other and wherein said generally axially extending openings are staggered with respect to each other and coaxially aligned with a respective piston bore whereby said openings define generally axially extending machine tool access openings which allow the piston bores to be machined by a suitable axial machining tool inserted into the associated openings.
An opposed piston caliper type of disc brake assembly for a vehicle comprising:
- a brake rotor;
- a pair of brake shoes carried by said disc brake assembly and adapted to engage said brake rotor;
- means for selectively moving said brake pads toward and away from one another;
- and
- an integral one-piece opposed piston brake caliper defining an axis and including an inboard leg and an outboard leg connected together by a bridge portion, said inboard leg having at least one piston bore formed therein, said outboard leg having at least one piston bore formed therein, said inboard leg having at least one generally axially extending opening formed therein which is coaxially aligned with said outboard leg piston bore, and said outboard leg having at least one generally axially extending opening formed therein which is coaxially aligned with said inboard leg piston bore.
A method for producing an opposed piston brake caliper comprising the steps of:
- a) providing a cast, integral, one-piece opposed piston caliper having an inboard leg and an outboard leg connected together by a bridge portion, the inboard leg having at least one as cast rough formed piston bore formed therein, the outboard leg having at least one as cast rough formed piston bore formed therein, the inboard leg having at least one as cast generally axially extending opening formed therein, the outboard leg having at least one as cast generally axially extending opening formed therein, wherein the piston bores are staggered with respect to each other and wherein the generally axially extending openings are staggered with respect to each other and coaxially aligned with a respective piston bore whereby the openings define generally axially extending machine tool access openings;
- b) providing one or more axial machining tools;
- c) inserting the one or more axial machining tools through the generally axially extending access openings;
- and
- d) operating the one or more axial machining tools to thereby machine and finish the piston bores.
