ABS can 'fix' all kinds of faults with a braking system. As long as the ABS
continues to work properly and dependably you should not have to worry
much. I really can't see the reasoning behind giving the rears more braking
power and then taking it back, in a panic stop or low traction situation by
relying on an Anti lock Braking System to save your bacon. Maybe it makes
the car 'ride better' day to day or maybe the engineers thought it would be
easier to replace pads more often at the rear wheels. Maybe they just
misscalculated the braking bias..
Whatever, the braking performance always depends on the available traction
at the tire contact patches. As soon as the forces overcome the traction to
a wheel, it is done helping you (much) stop until it regains traction..An
ABS system doesn't *increase force* to the skidding wheel, it tries to
momentarily release braking force to regain traction on that wheel...much
like old time racers or truckers 'pumped the brakes' during emergency
braking.
Very sophisticated ABS systems, like those found on some race cars or high
performance sports cars have the capacity to actually steer the car through
a corner above the limits of it's normal traction. The drivers just 'jam
the car' into a corner at a silly speed, stomp down on the brake pedal and
crank the wheel over. The ABS takes over from there, adjusting the traction
and braking to various ends and wheels of the car to get it round as best
it's been programed to do..The driver just sits there and hangs on with his
foot down on the brake until it becomes time to accelerate out of the
corner..
