Abstract
A hydraulic control unit (HCU) for a vehicle brake system having an HCU body and an accumulator mounted in the HCU body. A grommet is provided for mounting the HCU body to a vehicle body and resiliently separating the HCU body from the vehicle body. The grommet defines a vent path for the accumulator and includes a hollow generally cylindrical shaft. The shaft has a closed end and an open end, and the closed end has an opening therethrough. An enlarged annular head is formed on the open end of the shaft and has an inner surface defining an axial bore therethrough. The axial bore is in fluid communication with the hollow shaft, the annular head further has a crown cut geometry providing radially extending grooves within an axial face of the annular head, the radially extending grooves being in fluid communication with the axial bore of the annular head.
