The pertinent rule is:
23.12 The use of sensors fitted to wheels, lay-shafts or suspension units to aid traction control or active suspension is prohibited. The use of the third channel parameter on a receiver is limited to external power supply only (no signal circuitry allowed).

As long as they are driven only from the two steering and throttle outputs on the receiver and no external sensors are used there is nothing limiting how many servos you can use.

If someone want to use a servo for front wheel braking there's nothing stopping you doing that but the only control of it must be from the throttle output shared with the ESC, so you can't have it so it can vary brake balance between front and rear when running.
If for example you wanted to use servos to stiffen the springs/dampers during hard cornering you can technically do that, but it will be doing the same whether you are going really slow or flat out, there's no way of the buggy sensing how hard it is cornering.

Of course the BRCA has put in rule 23.13 so if the committee thinks you are adding driver aids they can ban it whether it's legal or not.

but the link in this thread to the guy with brakes clearly claims he uses servos and mixing ability, that example is illegal

yup he could use a y lead in the throttle port on the rx as i put earlier, to me against the spirit!
