Brake fluid change?

Question: I have the C7 GM manual and it details the sequence of inner and outer bleeders on the 4 corners. All Data shows only corners but no mention of inner & outer bleeders.
I had mine at a GM dealer recently and later I realized the only bleeded the outers.... saves having to remove the wheels. They contend that is all that's needed. I sent them the manual and they dismissed it and the ABS procedure. HACKS!

Although I do replenish the fluid in my two BMW's and motorcycles, and will do the corvette, I have never done it in any of the many vehicles I have owned, some accumulating well over two hundred thousand miles without an issue.

There is no actual flow cycle back to the reservoir.
You may very well never have brake issues, but that fact has less than nothing to do with your procedure which is a complete waste of time and does literally nothing.

I bought this bleeder kit from HFT two years ago and did the fluid change at that time on the C7. Just did my truck last week, very easy--or at least the bleeding part was easy. I removed the wheels on both vehicles, as using the kit might be difficult to manage when the wheels are installed.

As a FYI, the hose on the kit has a nipple on the end to push onto the bleeder valve, and it will suck air while the air pressure is applied. It doesn't go into the brake system but out with the old fluid, and some have tried using Vaseline or Teflon tape to insulate it better. One who commented on the HFT feedback said it worked fine when the nipple is removed and the bare plastic tubing fixed to the bleeder valve, and I may do this next time. It would be easier to see the transition of old to new fluid if it was not mixed with air.

I tried several suck type brake bleeders and then tried Motive. Once you try it you will never want to suck again.

Many find it best to not fill it with fluid and just use the air pressure to bleed the brakes (filling the reservoir between bleeding). If the Motive has fluid in it and the the master cylinder cap comes loose, it could spray brake fluid all over the paint.
