Hi I just want to mention the importance on replacing the brake fluid. It will make a big difference in terms of having more confidence when braking and feeling more safe. I did it with a friend using techstream to flush out the old brake fluid and replacing it with new .
The international LS manual says it should replaced every 2 years. While the US manual there is no mention.
I'd be willing to bet this is the source of our actuator woes. I had mine flushed and filled around 1.5 years back so it's coming up time to do it again.

This is interesting.. I was driving with badly pulsating brakes for several months and would get a loud actuator "squawk" almost every day. Since replacing all the rotors and pads with Centrics last month, I haven't heard a peep from the actuator. The fluid wasn't changed but the level in the reservoir did rise because of the new pads.
I agree with you 2133. There was a post from a guy a while back with actuator failure. He took the defective unit apart and came up with what looked to me like water contamination in one of the valves.
ALK - Congratulations on the successful bleed! It looks like a lot of work from what I've read. Where you able to access the bleeder screws on each caliper without removing the wheels? Or did you remove all the wheels and place on jack stands, or do one wheel at a time?

since we took our time I would say it took us 3.5 hours. That includes removing wheels and put on jack stands once that's done . All is required to to bleed from the bleeder screw. For RR and RL I put AIR bleeder mode in techStream. Just holding the brake then opening bleeder to the pump turns on . Once rear are done. The front are done manual . All just be prepared by techstream. All while maintaining the fluid level.
FWIW, my local Toyota dealer does this service for around 100 bucks. Hardly worth the aggravation to DIY.
Yes, but doing it DIY is much more satisfying . Also I have 2 other LS that need fluid change. My dealer does it for 250 that's including the fluid . while I did the whole thing for 28 bucks . Also don't forget that some Toyota and Lexus cars need Techstream to bleed and replace the fluid. While others can be done manually without software intervention .
Ok to do a partial flush, i.e empty the fill reservoir and add fresh fluid? I've been doing that for years. The cars I've purchase usually have pretty clean brake fluid to begin with. I usually do it twice a year with oil changes

well the idea is to change the fluid from master cylinder all the way to all brake calipers. I will upload the instructions later on.

I did that on my C6 Corvette - I don't remember why, but the brake fluid in the vette would get very dirty/very quickly. I think the idea is that the normal 'motion' of the brake fluid would eventually help clear out the lines. Not a perfect substitute for a full drain and bleed, but still good.

That's the budget approach. Problem is, the old brake fluid remains at the business end of the system.
Dont forget to replace the Brake Fluid
