Difference in Rear Wheel Drums for Alloy Non Alloy Wheels..
I need new rear brakes which are drums/shoes on a 2009 LT with 16 in alloy wheels. Due to the high mileage on the car, and I bought it used. I want to go new drums, shoes and springs/adjustors. I would also like to replace the fluid. I also want to have all the parts on hand so I am not running around looking for parts once I start.
In looking online for parts I have found there is supposed to be a difference between the drums for alloy wheels and non alloy wheels? GM wholesale and rockauto both have different drums for the type of wheel.
Anybody here know why that is? If the drums are 5 bolt why would it matter? Also will aftermarket steel rims with winter tires not work?
Thanks I have just never seen such a specification with any other car I have owned.
