lobuxracer, quick question since you seem very knowledgeable on brakes and most thing mechanical. you said changing out fluid, there is no need to cycle out the abs fluid unless air gets into the systems.

if i'm changing out the lines to stainless, wouldn't air be into the system meaning it's not really a diy at home anymore? what is the proper process on the ISF if i do get air into the system?

There's nothing in the service manual specifically addressing bleeding the ABS actuator. There are manufacturers who say you must cycle the ABS to get the air out of the system if air gets into the ABS pump. Lexus has a procedure using their Techstream tool to assist with bleeding, and although the manual doesn't say what Techstream is doing, it's more than likely holding the ABS valves in a specific state while you bleed the caliper at each wheel.

I have successfully changed lines without needing Techstream or some other SST on a few different Toyotas including my Supra, so the real key is to prevent the lines from leaking out all your fluid while you are doing whatever it is you need to break the system to complete. The first step in the brake fluid replacement procedure (which does NOT require a Techstream tool) is ensure the master cylinder is full of brake fluid and never let the fluid level go below the low line. If you follow this guidance, you won't need a Techstream device to bleed your brakes.

I also highly recommend Earl's Solobleeders to make the job a one person task. I put them on all my cars because it makes bleeding simple, and when you go to the track, you're going to be bleeding your brakes - in fact, you'll likely be doing a fluid replacement before a track weekend if you have any desire to be confident about your brakes.

thanks for the reply. so if i keep the master cylinder full, even when unbolting the oem lines and then reattaching the stainless, no air will be brought back in the system as long as the cylinder is full? my mechanic works at a dealership but doesn't have access to techstream but does have all the gadgets for brake fluid flush. i remember him having something attached to the master cylinder and hooking on a funnel/container by the hood latch and always making sure that it's full of new fluid and never running dry while bleeding.

Yes, as long as the highest point in the system stays full of fluid, you're good to go. The other trick is to put a 2x4 or some other kind of stop in the footwell under the brake pedal so you can't put the pedal all the way to the floor. This keeps the master cylinder from cavitating when you let up on the pedal.

This right here will help you big time. I use an old broom stick to hold the peddle. Once you have that thing depressed, aint nut'n coming in....

lobuxracer what is the thread pitch for the breaks?

M10 1.25? or 1.0?
