Pulsating pedal means either warped brake-rotors (or disks) or some bad wear
in the front steering/suspension which is going into oscillation on braking.
More likely to be the former tho.
Bdly warped rotors can actually push the caliper-piston back into its bore
as the 'high' side of the warp pushes past,..this has the effect of lowering
pedal height intermittantly, but nor making it spongey. What happens is, the
piston which is behind the brake pad is no longer running an interferance
clearance against the rotor,..so when the brakes are applied, some pedal
heigt is consumed taking up this gap.
However, the master-cylinder is a high contender for this fault as well:
Master-cylinders which change pedal height all the time, need reconditioning
or replacing. Ballooning flexible brake-hoses can cause this, but once soft,
stay that way every application of brakes.
If the rear drums have at one stage been turned on a lathe to remove heavy
scoring and the shoes are now the wrong radius,..soft springy brakes can be
If the front seal is worn in the MC, there will be oil leaking down the
front of the booster,..a slow loss of fluid and air continually getting into
the hydraulics causing a soft pedal..

If the strut ram is loose in its bush, it can make the car's frontend
unstable and cause uneven wear on its tire. It also can cause the road-wheel
to tilt slightly (goes positive
camber) on corners where its on the inside, causing oversteer.

Those little uni-joints do go tight in some cars (Nissan Pulsar is one),
and its possible cold weather could cause it to loosen-up or get tighter.
Your car needs sorting out properly, especially if you drive it on freeways
or long trips. Those brake symptoms are indicative of serious problems.
