For the inward retracting mains the autobraking is necessary when gear retracting for gyro forces, but for forward retracting nose, the braking is not technically necessary
However if there is a tyre imbalance you get a lot of yo-yoing in the cockpit. The snubbers strips (A320) slow the nosewheels quickly, but for some reason if there is a bit of a tyre imbalance, there is usually one last-gasp vibration before the wheel stops. Dont know why.
