Hmm, unfortunately not making much progress here. I believe the situation has been made worse - of the 2 ports on the master cylinder, the one closest to the front of the vehicle is fine but the one that comes into the side of it has a slight leak. Looks like I just didn't tighten it enough... my fault for not checking this.

I bet there is a shit ton of air inside the system now. I tightened down the brake pipe (Had to really go to town on it to get it to stop leaking). Hopefully this hasn't introduced too much more air into the system (since the reservoir has been pressurized to >15 PSI for the duration of this exercise

Can someone outline the EXACT steps that they are using when bleeding.

Here's what I've been doing:

1. Fill fluid + attach pressure bleeder to reservoir cap
2. Pump up the pressure bleeder to at least 15 PSI
3. Attach length of clear hose to the bleeder nipple valve & crack it open until I see fluid flow
4. Run the "bleeding routine" in ISTA/D (screenshot above)
5. After the bleeding routine completes, press brake pedal as far down as it'll go 5 times
6. Repeat steps 4 & 5 until roughly 2-300 mL (10 oz) of fluid emerges from the caliper

The sequence of bleeding is like so:

• Rear Right
• Rear Left
• Front Right
• Front Left

Does that look right?

If yes, how many times should I expect to repeat on each corner before I notice an improvement?
