Abstract
A brake circuit comprises a master cylinder in communication with a front wheel brake, and in communication with a rear wheel brake through a hydraulic line. A sensor senses pressure in the master cylinder, and an electronic control unit in communication with the sensor controls an apply valve to proportion pressure between the front wheel brake and the rear wheel brake.
Claims7
A brake circuit comprising:
- a front wheel brake;
- a rear wheel brake;
- a master cylinder in communication with the front wheel brake, and in communication with the rear wheel brake through a hydraulic line;
- a sensor for sensing pressure in the master cylinder;
- an apply valve in the hydraulic line;
- and
- an electronic control unit in communication with the sensor and with the apply valve, the electronic control unit controlling the apply valve to proportion pressure between the front wheel brake and the rear wheel brake.
