While compressing the piston, watch the brake fluid level - it will go up
and may overflow. You might need to extract some before you
put the cap back on.
Front brake pad and rotor replacement on a 1999 Saab 9-5. This guide will
also apply to NG900 and 9-3.
guide is available if you're looking to upgrade your brakes with 308 mm
rotors and Aero calipers.
After the installation, an aggressive bed-in is recommended. Find a street
with low traffic and a high speed limit. Do a series of moderate intensity
stops to heat up your brakes (or roll with a brake pedal slightly engaged).
Then do a series of really hard stops from 100 km/h to 10 km/h. Brake as
hard as you can, almost to the point of locking the wheels, but never come
to a complete stop, always keep the car moving. Do it 8-10 times, you might
notice a strong burning smell and some brake fade by the end of the series -
this is normal. Drive the car for another 10 minutes to let the brakes cool
