Hi all, 1986 C10 with 1" rotors. I did search, but had additional questions as well.

Last week I changed out my brake calipers and now my pedal goes to the floor. I can hold the truck, but I do not trust it to drive. One mistake I made was I left the RF bleeder loose and stepped on the brake. I heard the fluid squirt and panicked and released the brake pedal and it sounded like it sucked in air.


After that, I did the following:

First I bled just the fronts with no luck

Gravity bled all 4 starting with the RR LR RF LF method and still bad braking.

Pressure bled in the above same manner and still no luck.

I did accidently press on the pedal with the lid off of the MC, I did bleed again, but will this introduce air?

When bleeding the LR, there was a lot of air that came out. I would pressure bleed and pressure bleed, but the same amount would rush out every time. I have a hose attached to the bleeder screw which would suddenly jump at the end of the travel of the pedal.

I am at a loos and am running through brake fluid quickly. I can't find a lead, but I can hear the fluid squishing around when the pedal is pressed.

Pedal gets pressure when truck is off, but when I start it, mush...

I did not have these issues before the caliper swap.

Any ideas???
