Went for a drive around the block the check my bleeding job and the brakes were still a touch soft. Opening the MC and applying pressure I could see fluid rising back into the MC when the brake pedal was released. It looked like a very faint/slight liquid cone. Imagine a bubbler in a pond that barely cracks the surface and minimize the point to a pencil head. So I knew movement was happening, and knew I had just bled them a few days ago. I opened up the furthest line to re-bleed but no fluid was coming through, and my 13 year old helper said the fluid level was not going down and no bubbles were coming up. Hunching there was a blockage I loosened the fitting on the rear Tee going to the left rear and fluid was seeping between the threads. I was quite certain there was a blockage; especially considering the line I replaced where the hole previously was had severe rusting.
Sure enough, I pulled everything off from the front Tee to the rear, separated the individuals lines, and could not spray fluid through the hose just before the rear Tee. Since I had everything off and since it was the last nice day before more rain I made seven trips to parts stores to find a hose that would come close to a match so that I would not have to wait another week for an original part.
I had to make a couple adjustments such as cutting a slightly larger hold in the mounting bracket for the new rear Tee to fit, but it was worth it to get the lines redone before it gets cold here again.
