How do you change the brakes on a 2000 Saturn LS?
Get a manual on your car from the parts store for about $18 and it will help on the next repair.
The Saturn Ls1 that I own I have replaced the brakes twice and each time I am forced to buy the brakes frome Saturn although this car is 5 years old the parts for this 2000 Saturn LS1 are not allowed to be sold on the open market.
Yes, of course you can adjust the rear drum brakes. They should be self adjusting. Every time you back up and apply the brakes they should adjust themselves. If that is not working, look for a small rubber plug on the back of the backing plate. Remove that plug and with a brake adjustment tool, you can adjust the brakes. Search Google for the proper procedure to adjust drum brakes.
You don't. The 2000 Saturn refrigerant is not Freon R12 it contains R134a. Add it at the Low pressure port. You have a leak or it would not be necessary to add refrigerant. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Take it to a professional and have the leak fixed.
