Refilled with new DOT 3 then proceeded to follow your advice. Then I used a vacuum pump to pull out as much old fluid from the master cylinder as my hose would reach.
I wanted to get a good new baseline, so I replaced the rubber hoses with stainless, rebuilt the calipers, put on new pads (with shim kits) and all new rotors. The old fluid has a dark caramel color, and from the looks of the old calipers/pads I'd say the truck never had anything done to the brakes except push the pistons back and slap in some new pads (broken retaining springs, etc.). At the end of this I usually end up with a quart or so of brake fluid that's been through the system, I've heard ABS solenoids click on/off via Techstream and I usually imagine my brake pedal feel is better. Anyway the order of attack for me when doing a brake fluid exchange has been to do the "Bleed Brake Line" at each corner bit, then go back with Techstream hooked up and bleed as per the fsm steps you quoted. It's the section with bolded Bleed Hydraulic Brake Booster where parts (d) and (e) direct you to Step 4 on the last page where you Bleed Brake Line. Now my interpretation of this tragically written piece of JapEnglish of a procedure is that an "ordinary" brake bleed - ignition on, pedal depressed (not pumped) and bleeder opened- is achieved without using Techstream by following the prompts in Point 2 immediately preceding the "with hand held tester" stuff. I've done the Techstream ABS bleeding as per the FSM extract above and it works - or at least the 4 second counter times off, solenoids click and fluid pulses out at the respective caliper. (2) With ”RR LINE” turned ON with the TOYOTA hand-held tester, bleed the left and right rear brake caliper. (1) Select ”RR LINE” on the TOYOTA hand-held tester. (2) With ”FL LINE” turned ON with the TOYOTA hand-held tester, depress the brake pedal and hold it to bleed the left front brake caliper. (1) Select ”FL LINE” on the TOYOTA hand-held tester. (3) Repeat step (2) until there are no more air bubbles in the fluid.
(2) With ”FR LINE” turned ON with the TOYOTA hand-held tester, depress the brake pedal and hold it to bleed the right front brake caliper. (1) Select ”FR LINE” on the TOYOTA hand-held tester. Refresher for those who haven't seen the FSM for a while. Would the process in the 2004 FSM for the LC also apply to my 2000 LX, e.g., no pumping, just hold the pedal, open & then closing the bleeder while Techstream does its thing? I have quite a few years experience bleeding using the "assistant, pump three times and hold" method, but would really like to learn "the Toyota way" using Techstream (and of course I'm curious and want to learn). Pretty sure my trucks fluid has never been touched so I want to clean it all out. I took Techstream far enough that it asked me to select which line FR, FL, RR, or RL and IIRC correctly it hinted at the 4 second period in which the solenoid for the selected wheel is open (2 seconds of actual fluid flow). I feel pretty confidant that using Techstream bleeds the ABS at the same time as the lines. I have read most, if not all, the threads on bleeding the brakes.
