[QUOTE="jasona1700, post: 537893, member: 14731"] OK. I'm loosing my mind here. Hopefully some of you can help. I bled the front brakes on my '06 first and everything went fine. But here's the problem. I went to bleed the rear, and committed the ultimate sin. I emptied reservoir my mistake. So I refilled it, and pumped out what I thought was all the air in the line. So now pressure will build in the system, and it feels strong. But if I wait a second or two, the rear pedal pushes the full length of travel with little or no resistance. I have gone through 2 bottles of DOT 4 with no bubbles coming out when I release the bleed nipple. This is driving me crazy! Could I have air in the manifold that connects the front and rear brakes? And if so, how do I get that air out? I called the dealer, and he said I could have air trapped at the top of the caliper. But the nipple is towards the top of the caliper. I even tried tapping the caliper with a rubber mallet to work out some bubbles. No luck. I have tried sucking the fluid out with a vac, no bubbles. I even put a little teflon tape around the threads of the nipple, no bubbles. Help!! Thanks. [/QUOTE]
