Rear Drum Brakes (2007 Model)

[chrisu91]

Hey there!

Just had a brake inspection done and it was determined that I need to get my rear drums replaced within the next three months. Furthermore, I should replace both rear wheel cylinders and "steel brake lines from wheel cylinders to rear flex lines".

I found the part number for the rear wheel cylinder but GM wants $112 EACH!
Here's the OEM part: Amazon.com: ACDelco 174-1117 OE Service Rear Brake Cylinder Assembly: Automotive
Here's a comparable one: Amazon.com: ACDelco 18E1412 Durastop Professional Drum Brake Wheel Cylinder: Automotive

Perhaps a stupid question, but is it really worth more than 5x the price to get the OEM part or should the comparable one get the job done just as well?

And lastly, I have to replace that "steel brake line" between the wheel cylinders and flex lines however I am unsure what part number that is. If anyone could provide some insight into that I would appreciate it!

EDIT: I think this is the steel brake pipe that the mechanic was referring to. http://www.amazon.com/ACDelco-964702...1&s=automotive
Do you know if this would work for either the left or right side or are they separate part numbers?
