Hello, I recently did an install of ss lines. Prior to the install, I had bled the brakes at the caliper (since I installed speed bleeders), and had a very high/firm pedal as a result. Since the car was up on jack stands, I picked up a set of SS lines and installed those. They went in dry, but after I went to bleed the car here is what happened.

1) Very little air came out of the rear calipers. But I bled them until no air or bubbles came out. This includes inner and outer bleeder valves.

2) The inner valve of the front calipers made strange squishy noises and endless micro bubbles kept coming out. After going through several liters of fluid, I ran a clear hose from the passenger caliper to the MC until clear fluid came out. I repeated this for the driver side front but by then, it seems I may have gotten all the bubbles out the passenger side.

3) I did bleed using the Correct X pattern given the brake circuits on this car. I drive a BMW M3 and have experience with BBK, SS lines, replacing and bench bleeding MC and replacing brake boosters. In addition to pressure bleeding, vaccum bleeding and the two man method.

However, this was the first time bleeding this car.

Another point to add is that I did try to use my motive bleeder using a metal cap adapter I picked up via Amazon. Unfortunately that cap wasn't able to hold pressure and made a mess. I also saw an exorbitant amount of air bubbles being pushed into the MC where I've never seen before with the BMW. I'm not sure if this was part of the issue so I wanted to call that out.

Does anyone have any experience bleeding a caliper with an endless supply of air bubbles? Never seen anything like it. I purchased a device to help me with the ABS bleed in case that helps. I'll have it tomorrow so we'll see but looking for input in the meantime.

Thanks.
