You are so right. During the 2008-2009 meltdown the dealership I was using at that time for my Buick couldn't do enough to satisfy me. Then as things improved that changed. Several months ago I received a coupon from them for a really cheap oil change. I did go there and I was treated almost hostile even though they knew me as I had been a customer there for more than 10 years.
I did go to the Chevy dealer to follow your suggestion on the brake flush questions. I was told they do a flush, not just a drain.I never got the chance to get any specifics on how they do the flush. Even though I pointed out that I had exceeded the recommended 3 years for a flush, I was told I would not need a flush because when they do any kind of service they always do a free multi-point inspection which would determine if I needed any service..
At that point, I asked that the need for a brake flush can be determined visually by the mechanic. They said YES by looking at the fluid.
Since you've had this done many times, is that correct?
For many years, I have purchased my vehicles new and maintained them very well (myself or by dealer or garage). For many years, I did most of my own maintenance for my familyís vehicles. Due to several surgeries - I am limited to basic, easy maintenance now.
I have generally had the brake fluid changed in my vehicles about every 5-6 years - professionally, such as a dealer who was able to flush it correctly. Many, many years ago (before the advent of ABS pumps), I had changed the fluid myself.
Brake fluid darkens with age and is hygroscopic (absorbs moisture readily). There are disposable tests strips which you can buy and use to determine if the moisture level is high, requiring the fluid to be changed.
I suspect the dealer is telling you the mechanic can tell when to change the fluid, as it is ďtoo darkĒ and needs changing.
Peace of mind is cheap - if youíre concerned, I would have the fluid changed by a reputable dealer - especially if you intend to keep your vehicle.
