## Abstract

A brake rotor assembly having a brake rotor and a brake rotor weight. The brake rotor weight may be received between vanes of the brake rotor. The brake rotor weight may include a hook arm, a guide arm, and an intermediate portion. The intermediate portion may bias the hook arm in the guide arm against the vanes.

## Claims

### Claim 1

A brake rotor weight comprising:
a hook arm that has a hook disposed at a first end and a first bend disposed at a second end;
a guide arm that is spaced apart from the hook arm and that has a first guide arm end and a second bend disposed at a second guide arm end, wherein the guide arm does not have a hook at the first guide arm end; and
an intermediate portion that extends from the first bend to the second bend.

### Claim 2 (depends on 1)

The brake rotor weight of claim 1 wherein the intermediate portion is disposed between the hook arm and the guide arm.

### Claim 3 (depends on 1)

The brake rotor weight of claim 1 wherein the first bend is spaced apart from the second bend.

### Claim 4 (depends on 1)

The brake rotor weight of claim 1 wherein the intermediate portion is spaced apart from the hook arm and the guide arm between the first bend and the second bend.

### Claim 5 (depends on 1)

The brake rotor weight of claim 1 wherein the intermediate portion further comprises a first intermediate arm and a second intermediate arm that are disposed between the hook arm and the guide arm.

### Claim 6 (depends on 5)

The brake rotor weight of claim 5 wherein the first intermediate arm extends from the first bend to an intermediate bend.

### Claim 7 (depends on 6)

The brake rotor weight of claim 6 wherein the second intermediate arm extends from the second bend to the intermediate bend.

### Claim 8 (depends on 7)

The brake rotor weight of claim 7 wherein the first intermediate arm is disposed between the hook arm and the second intermediate arm.

### Claim 9 (depends on 7)

The brake rotor weight of claim 7 wherein the second intermediate arm is disposed between the guide arm and the first intermediate arm.

### Claim 10 (depends on 7)

The brake rotor weight of claim 7 wherein the intermediate bend is disposed between and is spaced apart from the hook arm and the guide arm.

### Claim 11 (depends on 7)

The brake rotor weight of claim 7 wherein the intermediate bend is disposed at a first inner end of the first intermediate arm that is disposed opposite the first bend and at a second inner end of the second intermediate arm that is disposed opposite the second bend.

### Claim 12 (depends on 5)

The brake rotor weight of claim 5 wherein the hook arm is longer than the guide arm.

### Claim 13 (depends on 12)

The brake rotor weight of claim 12 wherein the guide arm is longer than the first intermediate arm and the second intermediate arm.

### Claim 14 (depends on 13)

The brake rotor weight of claim 13 wherein the first intermediate arm and the second intermediate arm have substantially the same length.

### Claim 15

A brake rotor assembly comprising:
a brake rotor that has a brake rotor opening and first and second vanes that extend from a first panel to a second panel, the first and second vanes each having a first vane end that faces toward the brake rotor opening and a second vane end disposed opposite the first vane end; and
a brake rotor weight that is received between the first panel and the second panel and between the first vane and the second vane, the brake rotor weight including:
a hook arm that extends along the first vane and that has a hook that extends partially around the first vane end of the first vane;
a guide arm that extends along the second vane and that is spaced apart from and that does not extend around the first vane end of the second vane; and
an intermediate portion that is disposed between the hook arm and the guide arm, wherein the intermediate portion biases the hook arm against the first vane and biases the guide arm against the second vane.

### Claim 16 (depends on 15)

The brake rotor assembly of claim 15 wherein the intermediate portion further comprises a first intermediate arm and a second intermediate arm that are disposed between the hook arm and the guide arm.

### Claim 17 (depends on 16)

The brake rotor assembly of claim 16 wherein the brake rotor weight further comprises a first bend that extends from the hook arm to the first intermediate arm, a second bend that extends from the guide arm to the second intermediate arm, and an intermediate bend that extends from the first intermediate arm to the second intermediate arm.

### Claim 18 (depends on 16)

The brake rotor assembly of claim 16 wherein the hook arm engages the first vane continuously between the hook and the intermediate portion and the guide arm engages the second vane continuously between a first guide arm end and the intermediate portion.

### Claim 19 (depends on 17)

The brake rotor assembly of claim 17 wherein the first intermediate arm engages the second intermediate arm.

### Claim 20 (depends on 17)

The brake rotor assembly of claim 17 wherein the hook arm is spaced apart from the first intermediate arm and the guide arm is spaced apart from the second intermediate arm.
