Abstract
A hydraulic caliper assembly includes a caliper brake housing including two opposing pairs of two piston assemblies, each of the pairs of two piston assemblies adapted to place a respective stator assembly of a pair of stator assemblies in a braking position, where the caliper brake housing is a unitary, cast component having an internal fluid porting system fluidly coupling each of the piston assemblies with a source of hydraulic fluid, and where each of the piston assemblies have a common configuration.
Claims11
A hydraulic caliper assembly comprising
- a caliper brake housing including two opposing pairs of two piston assemblies, each of the pairs of two piston assemblies adapted to place a respective stator assembly of a pair of stator assemblies in a braking position,
- wherein the caliper brake housing is a unitary, cast component having an internal fluid porting system fluidly coupling each of the piston assemblies with a source of hydraulic fluid, and
- wherein each of the piston assemblies have a common configuration,
- each of the piston assemblies including
- a piston bore having a piston slideable therewithin,
- the piston bore having
- a piston groove formed therein and carrying a piston seal, and
- a piston boot groove formed therein and carrying a piston boot, the piston boot groove being spaced from the piston groove, and
- a piston O-ring plug having a plug body portion adapted to fit within a portion of the piston bore.

A hydraulic caliper assembly comprising
- a caliper brake housing including two opposing pairs of two piston assemblies, each of the pairs of two piston assemblies adapted to place a respective stator assembly of a pair of stator assemblies in a braking position,
- wherein the caliper brake housing is a unitary, cast component having an internal fluid porting system fluidly coupling each of the piston assemblies with a source of hydraulic fluid, and
- wherein each of the piston assemblies have a common configuration,
- the caliper brake housing including a pair of threaded holes each adapted to receive a respective bolt, each bolt being provided with a respective washer, and

A hydraulic caliper assembly comprising
- a caliper brake housing including two opposing pairs of two piston assemblies, each of the pairs of two piston assemblies adapted to place a respective stator assembly of a pair of stator assemblies in a braking position,
- wherein the caliper brake housing is a unitary, cast component having an internal fluid porting system fluidly coupling each of the piston assemblies with a source of hydraulic fluid, and
- wherein each of the piston assemblies have a common configuration,
- wherein each stator assembly of the pair of stator assemblies includes a respective backing plate having a tab as an extension of the backing plate,
- wherein the tab includes a slot having a first end within the tab and a second end within the backing plate, wherein the slot defines a tool-engaging surface in the backing plate, such that a user can use a tool to apply sufficient force on the tool-engaging surface to thereby cause the respective stator assembly to move against the respective pair of piston assemblies,
- the caliper brake housing further including a recess positioned over the pair of stator assemblies,
- wherein each tab extends beyond an outer perimeter of the caliper brake housing and through the recess thereof, such that tabs are adapted to be grabbed by a user for rotation of the pair of stator assemblies,
- the caliper brake housing further including a respective depression corresponding to the position of each of the tabs.
