Embarrassing Brake Question

["Forhan, Thomas" <Thomas.Forhan@mail.house.gov>]

Embarrassing 'cause of all the do-it-yourself upgrade-to-red talk; I'm a 
bit of a nervous newbie!

Front and rear pads need replacing on my '90 200Q IA Stage I wagon, used as 
the number one family car.

I want to do it myself, but never have before. The Bentley looks pretty 
straightforward, although it gives wear limit numbers on the calipers, and 
 I vaguely remember discussions on the list suggesting they need to be 
replaced regardless. I'm OK with pressure bleeding the brake system (thanks 
Mike) , but really  the most complex thing I've done on the car is the door 
lock fix.

Any hints, minor upgrades, cautions, preferred vendors?

Thanks,

Tom F.
