Its been a couple of years since I changed out my brake fluid on my '89 Toyota pickup truck. Can someone tell me the best method for having a shop change the brake fluid out? I am going to use DOT4.I heard with "partial " flushes, so much old fluid remains in the lines and in the Master/slave Cylanders. What method completely flushes the fluid?What service do I ask for? thanks!

I have an 89 Civic and have never changed the brake fluid, with no ill effects. It's a closed system, I didn't know it "wore" out? As a matter of fact, I have never changed the brake fluid on any vehicle I have ever owned in over 30 years.
Brake fluid oxidizes, absorbs moisture, and gets abrasive particulate matter in it.
A good flush every 2 years or so is a great idea.
You want a standard brake bleed.
Suck the master cylinder almost dry, then fill with fresh fluid. Bleed the brakes.

Pretty bad advice, I would siphon off master every 2 years if not mechanically inclined to do bleeds. If you bleed via the bleeder screws on all 4 sides one could take the interval to 3 yrs.
Unless you can cycle the ABS solenoids you will not be affecting the fluid inside the module. Not a whole lot in there anyway.
You can flush the brakes and fill with all all new fluid. Go out on a gravel road and at low speeds 10-15 mph repeatedly lock up the brakes to kick in the ABS. Then flush the brakes again.

Oh yeah... ABS systems often have special bleeding techniques.
But if you can't get a special tool - do what you can the standard way - the residue will mix and be better than before.

How to bleed completely the old brake fluid?
Thanks.
Thanks.
Well. I took off the 9yo calipers from the CRV today. I had fully blead the lines a year ago, but the fluid INSDIE the caliper cyl bore was black as I poured it out. Bleeding without depressing the caliper cyl bore (w/new pads) is pointless as far as refreshing the system. On VAG cars, you can cycle the ABS unit, but it is NOT necessary.
