Bleeding Brakes - Toyota 4Runner Forum

I have a question. I used a pressureized system to bleed my brakes yesterday. Well, while bleeding the left rear, I had let too much fluid out and it got to the point where only air was coming out. I topped off the brake fluid reservoir and reblead the left rear until the brake fluid ran clear. Do you think there's any trapped air in the lines? Master Cylinder?

I bleed the left rear once again to make sure I got any visible air out and think its good. Much thanks if you can chime in.

It would probably be a good idea to bleed the entire system again. It's very possible that there is still air in there because the reservoir ran dry.

What's interesting is that the resivoir didn't run dry. There's still fluid around the min level. I was going back to check how the pressure was, when I heard the gurgling coming from the bleeder tube. I freaked out thinking all the fluid must have left the container but that didn't happen.

I'm thinking each line is independently hooked into the master cylinder and that refilling/re bleeding would push fresh fluid back out the valve being bled.

If this is true, there is no real order in which you should bleed your brakes.

Anyone else have experience with 4th gen brake systems?
