Got on gmpartsdirect, don't even show a parts diagram for what is required to convert, and several of the parts you know are needed are not even listed. But what are, would be a small fortune to convert.
With all the pros listed for rear disk brakes, maybe instead of complaining about them, should brag instead.
Ha, ha, my car does have disk brakes, ha, ha, and yours don't!
But this is based on over 33 years of experience in dealing with rear disk brakes. Unlike regular calipers that are inherently self adjusting, these require esoteric knowledge on how to operate the parking brake for adjustment. And the mechanism itself is exposed to road hazards, not a closed system like standard calipers. When the pad gap increases, and the brake level returns to the home position, a dog slips into a ratchet gear and turns and exposed screw to close the gap. That in a couple of years would be a pile of rust.
One thing I would say in favor of the Cruze, they finally plated the parts. But see on my levers, surface rust is starting to appear. Just a quick glance at the plating equipment? But my next job is to clean the external surfaces and hand paint them. Removing any caliper also requires specialized equipment to active the the ABS for proper bleeding. Unless you know how to work around that.
Also see a new ABS costs 1/20th the price of a new Cruze, just for two components you can barely find in the car. But did fine a rear disk caliper rebuilding kit for 20 bucks, least I think its for the rear calipers.
But just for a quick price comparison, and not knowing if the ABS has to be changes as well, these to have to be tuned for the car, along with the rest of the parts. If you really want rear disk brakes, think it would be cheaper to trade your Cruze off for one that has them.
For me a trade off, wanting a power driver's seat, better radio, a spare tire, leather interior with electrical heated seats, a thousand buck option with a 200 buck discount. They tossed in the rear disk brakes in free. But expecting a huge return for service. Doing this for the dealers with all these dealer installed options.
What's next on their list? Instead of giving us a discount, will be getting worthless points like everyone else is doing.
