In the process of bleeding brakes and keep getting bubbles...
I finally got around to installing my Tundra calipers and rotors along with some Goodrich SS lines. Now when I am trying to bleed the brakes I am stuck on the first wheel, the rear passenger. Bubbles just keep coming out, does anyone have advice for this? Do you think one of the SS lines isn't fitting right and it's sucking in air? Any help would be appreciated

i thought maybe the pedal was getting depressed or released too quickly. or perhaps it wasn't gettin 'pumped' enough, but with expieriace...hmmm
are they little bubbles or big bubbles (gaps in the fluid)

Best way to do it is to do a gravity bleed first, crack all the bleeders so they have brake fluid coming out, with the cap off the reservoir, fill the reservoir up, grab a beer, and wait about 20 mins, close all the bleeders and start bleeding with the corner furthest away from the reservoir, going to the next furthest, and so on, repeat about 2 times, and you should have a rock solid pedal.

I think what you're seeing are bubbles introduced at the bleeder valve as the brake fluid is coming out. Try cracking the valve open just a bit further to see if the extra flow doesn't eliminate the 'valve gurgle'. To help eliminate this, find a small length of clear tubing to slip over the bleeder value. Be careful not to over pressurize the Master Cylinder when the brake pedal method. For best result, either a gravity feed or Motive Brake bleeder is best.

The bleeder we tried to use was a gravity feed over the reservoir and then a hookup that is under suction by air compressor at the bleeder valve. It has a special hookup to the bleeder valve, we tried that and just the clear tube. Also tried the standard two man bleeding technique.

I've always wondered about that - what causes gaps in the fluid in the line between the bleed valve and the drain bottle???

Well, yeah. Tiny little bubbles that come out of the cylinder when the valve is open. But what about after the valve is closed - And I know I don't have any leak between the clear tube and the valve (it went on tight enough!)
