Abstract
An anti-squeal braking system for an automotive vehicle, including a first brake having a brake rotor, a friction member disposed opposite to the brake rotor, and a hydraulically operated actuator for forcing the friction member against the brake rotor, and further including a second brake cooperating with the first brake to apply a brake to the vehicle. The first and second brakes are controlled by an anti-squeal controller such that the first brake is operated without a braking squeal, while the second brake is operated so as to provide a braking effect equal to a difference between an actual braking effect applied to the vehicle by the first brake, and a desired braking effect that should be applied to the vehicle. The desired braking effect is predetermined corresponding to an operation value of an operator-controlled brake operating member sensed by a detector device.
