left front brake caliper hanging up
replaced the rear wheel cylinders
tried blocking off both ports and the pedal didn’t move (not sure if this is a legitimate test hahahah)
blocked of rear still does it.
thought I had replaced the calipers but evidently I put the old ones back on once the master fixed t he caliper hanging up.
tried blocking off the left caliper and it still did it. This sucked and didn’t want to try it on the right side. Used grease to seal the threads when bleeding.
used one of these to bleed the brakes.
ordered some calipers. Still unsure on if the master is to blame.
