## Abstract

A braking assembly for an air disc brake comprises an actuator assembly having a service portion, at least one mounting stud attached to the service portion, and an air disc brake caliper having a bore for receiving the at least one mounting stud. The mounting stud is pivotable with respect to the service portion for installation on the air disc brake caliper.

## Claims

### Claim 1

An actuator assembly for an air brake system comprising:
an actuator housing having a service portion;
two apertures in the service portion of the actuator housing of the actuator assembly;
two receiving portions affixed to an interior of the service portion at each of the two apertures; and
two mounting studs, each of the two mounting studs having a threaded portion at a first end and a rounded head opposite the first end, each rounded head inserted into each receiving portion, wherein each threaded portion is exterior to the actuator housing and the two mounting studs pivot in a plane parallel to an axis of the actuator assembly during installation of the actuator assembly to an associated air disc brake caliper.

### Claim 2 (depends on 1)

The actuator assembly as in claim 1, wherein the two mounting studs and the two apertures are sized to allow pivoting between zero and about twenty degrees with respect to the axis of the actuator housing.

### Claim 3 (depends on 1)

The actuator assembly as in claim 1, further comprising a snap ring for holding each mounting stud in each receiving portion.

### Claim 4 (depends on 1)

The actuator assembly as in claim 1, further comprising a pin for holding each mounting stud in each receiving portion.

### Claim 5 (depends on 1)

The actuator assembly as in claim 1, wherein the two apertures are radially equidistant from the axis of the actuator assembly.

### Claim 6

A braking assembly for an air disc brake equipped vehicle comprising:
an actuator assembly having a service portion housing, the housing having at least two apertures;
at least two receiving portions affixed to an interior of the service housing at each of the at least two apertures;
at least two mounting studs, each of the at least two mounting studs having a threaded portion at a first end and a rounded head opposite the first end, wherein each rounded head is mated with each of the at least two receiving portions, the threaded portion of each mounting stud being exterior to the service portion housing and the at least two mounting studs being pivotable with respect to the service portion housing; and
an air disc brake caliper having an angled mounting face with respect to a centerline of the air disc brake caliper and at least two bores through the angled mounting face for receiving each of the threaded portions of the at least two mounting studs.

### Claim 7 (depends on 6)

The braking assembly as in claim 6, wherein the at least two bores are parallel to the centerline of the air disc brake caliper.

### Claim 8 (depends on 6)

The braking assembly as in claim 6, wherein the mating of the actuator assembly with the air disc brake caliper forms an air tight seal.

### Claim 9 (depends on 6)

The braking assembly as in claim 6, wherein the angled mounting face is between a zero degree and about twenty degree angle with respect to the centerline of the air disc brake caliper.

### Claim 10 (depends on 6)

The braking assembly as in claim 6, wherein each threaded portion mates with a nut through each of the at least two bores in the air disc brake caliper.

### Claim 11 (depends on 10)

The braking assembly as in claim 10, wherein the air disc brake caliper is sized to receive a tool to install the nut on each threaded portion wherein the tool does not interfere with a housing of the air disc brake caliper.

### Claim 12 (depends on 9)

The braking assembly as in claim 9, wherein the actuator assembly mounts flush to the angled mounting face when installed to the caliper.

### Claim 13 (depends on 10)

The braking assembly as in claim 10, wherein the actuator assembly pivots with respect to the caliper as each nut is threaded to each threaded portion to mount flush with the angled mounting face.
