400i brakes:
Fitted with ventilated cast-iron discs front and rear, with four cylinders per caliper. A tandem master cylinder operates dual hydraulic circuits, which feed the opposite pair of cylinders on each wheel. A pressure-limiting relief valve is fitted to each rear braking circuit. Vacuum servo-assistance is provided via a vacuum feed taken from the rear of the left-hand inlet manifold. This is supplemented by a Bonaldi 14-0634 vacuum pump mounted on the front right-hand side of the engine and driven from the inlet camshaft via a keyed shaft.

The handbrake operates, via a cable, on a set of shoes inside each rear hub. Adjustment to the handbrake is provided by twin adjusters accessible though the front of each rear hub.
