Abstract
Official abstract text for this publication.
Disclosed herein are a pre-fill system to improve brake feel and a method of increasing an initial flux using the same which may reduce an invalid travel distance of a brake pedal. The pre-fill system includes a first housing connected with the master cylinder and provided with a first bore having a smaller-diameter portion and a larger-diameter portion, a second housing provided with a stepped second bore communicating with the first bore to be coupled with the first housing to define a hydraulic pressure chamber, a piston arranged in the first bore and provided with an oil channel unit, and a valve assembly adapted to open and close the oil channel unit of the piston according to the hydraulic brake pressure, wherein the piston applies pressure to the hydraulic pressure chamber through the piston to supply hydraulic pressure to the disc brake.
First claim
Opening claim text (preview).
What is claimed is: 1. A pre-fill system installed between a master cylinder and a disc brake to increase an initial flux in braking, the pre-fill system comprising: a first housing connected with the master cylinder to receive hydraulic brake pressure and provided with a first bore having a smaller-diameter portion and a larger-diameter portion extending from the smaller-diameter portion; a second housing provided with a stepped second bore communicating with the first bore to…
