Probably basic hand tools and perhaps a brake spring tool.
If you pick up a shop manual for the car and read their directions,
you should get some idea what you'll need.
The only part that is needed to replace your 1997 Pontiac rear brakes is a break assembly kit. The brake assembly kit will have everything you need.
You need a 3/8" allan key or hex socket - not a torx
4.5 quarts
4.5-5
I'd suggest picking up a Haynes or Chilton manual for your car. It will take you through the procedures and will let you know what you need, if you read the procedure before you begin the job.
A 1996 Pontiac Sunfire uses Dexcool coolant. This should only be mixed with distilled water, never tap water. Replace the coolant every 2 years or as needed.
5 quartz or 4.8 liters.
5 quarts or 4.8 liters of motor oil
all Sunfires are 4 cylinder engines, so 4.
a torx bit size t-55 for front brakes

the same way as you would on a RWD or AWD car. but more information is needed to answer such a question. what part of the brakes????
