231mm bleeding issues?

[LINY4Runner]

I just did the 231mm Tundra brakes, and my bleeding didn't go so great.

I bled them as you're supposed do, I cycled through just about a quart of fluid, no air at all. And it's still taking 2 pumps to get a good feel.

I know my rears are out of adjustment, but that shouldn't make a difference because the brakes felt fine before doing the swap.

Any ideas?

did you bleed all 4 corners or just the front 2?

Is it possible to put the calipers upside down on the wrong side? Cause I've done that before on a F*rd.

I bled all 4 wheel in the correct sequence.

I'm a 5 year toyota tech, but I'm a little out of practice lately

LINY, Adjust your your rear shoes unless you've done it already. I have been caught many times "oh it was fine before". If it's far out of adjustment means your rear wheel cylinders have to travel farther right?

Yeah I'll have to try that tonight...

I'm gonna look into bench bleeding the master, although I'm not really looking forward to taking that thing out =/
I'm sure I could swing it with it still installed...

I'm no where near being a Toyota tech but I can tell you the rear brakes took me 3 times before all the air was out. For some reason, cracking the bleeder valve wasn't doing it. I had to crank it open wide, real quick, and then the air would belch out. But your symptoms definitely sound like air in the system and it's exactly how my brakes felt after just working on the rears.

 

[LINY4Runner]

okay so check it.

cranked the rear adjusters as much as I could because, well, I like my brakes like i like my women...tight :lol:

so I went to bleed the brakes again, and when I cranked open the rear bleeders...NOTHING came out...wtf? yeah.

So i took it for a drive, came back and tried again on the rear bleeders.

This time it coughed.
So I went back and fourth in my driveway, nailing the brakes in reverse, and that got it to sputter again.

Finally did it enough to get a steady stream again, but the brakes still don't feel right to me...it still takes 2 pumps to get it to feel how it should...

anyone have any ideas why I have to drive between squirts to get it to work?

May be a dumb question, but I'm just finding this out as well since I'm going to be replacing my brakes myself, but did you follow the break in instructions for the pads? My EBC's came with about a list of instructions about 15 items long on how to properly break in the new pads. Maybe there's a clog in the old lines?

LINY it just occured to me, I think you need the Techstream to bleed it. Since yours is an 01-02

my A Tech said it just gets bled like standard...hmm...unless he thought my truck was older...

I'm certain, I did a brake bleed on an 02 with the fancy Master Cylinder like yours with a techstream.

Wow...okay I'll have to get on that...thanks bud! I'm gonna work it out tomorrow and let you know!
