A brake assist system comprising an intermediate spring combined with a compression thrust bearing, limiting the compression to a force greater than the response of the brake pedal under normal operating conditions. The spring and its compression thrust bearing are placed between the plunger piston (2) and the helper piston so that the spring transmits the thrust from the helper piston to the plunger piston that pulls the pedal under normal braking conditions. The helper piston pushes the plunger piston by way of the compression thrust bearing when the response of the plunger piston exceeds the compression threshold. A contact detector detects the contact between the helper piston and the thrust bearing.
