Abstract
A rate control system is disclosed for use in a brake testing apparatus which applies an automatically controlld force to the vehicle braking system being tested. The rate control system varies the rate of flow of hydraulic fluid displaced as the brake pedal moves on its brake application stroke, in response to the rate of increase of a feedback signal which represents the vehicle stopping force, or brake effort, measured at a vehicle wheel. Varying the rate of flow of hydraulic fluid controls the rate of application of the vehicle braking system during the test.
