A method of adjusting test braking pulses during stability control of a vehicle () including the steps of: applying a first test braking pulse to at least one wheel of the vehicle (), the application of the test braking pulse comprising operating a brake actuator () to apply a low level braking pressure of the wheel, determining a first longitudinal acceleration (A) of the vehicle () during the test braking pulse, obtaining a second longitudinal acceleration (A) indicative of the longitudinal acceleration of the vehicle () when a test braking pulse is not being applied, calculating a change in longitudinal acceleration during the test braking pulse, and determining whether the change in longitudinal acceleration is acceptable, and if not, adjusting the level of the braking pressure applied in a subsequent test braking pulse.
