Ford 1997 Aerostar Manual page 165

If during normal operation the brake pedal
seems "low", it may indicate the need for a
brake system inspection and/or service. You
should have your brakes checked as soon as
possible.
Occasional brake squeal during light to moderate
stops does not affect the function of the brake
system and is normal. However, if the squeal
becomes louder or more frequent, have your
brakes inspected by your dealer or a qualified
service technician.
Modifications to the suspension spring
rates and/or vehicle ride height may
adversely affect vehicle stopping ability.
If Brakes Pull
Check tire pressure.
Perform the self-adjustment procedure
described under If Brakes Do Not Grip Well or
Pedal is "Low."
If pull occurs during the first 500 miles
(800 km), make 10 moderately fast stops from
40 mph (65 km/h) and then perform the
self-adjustment procedure above. It may be
necessary to repeat this operation to properly
seat new brake linings and pads.
Stopping Distances
Stopping distances vary with different loads and
driving conditions. Use caution when
encountering new conditions and acquaint
yourself with vehicle performance. Take full
advantage of engine braking power when
slowing down.
