I changed all the brake hoses (new). My master cyl. showed signs of leaking so I changed that as well (had one laying around). I bled the pass. rear, perfect. I bled the driver side rear, perfect. I tried to bleed the pass. front and it spurted out a bit of air and fluid and after that initial spit, nothing further. Same thing with the driver's side.
Are my caliper's stuck in a position where they do not let fluid to go thru, or do I have another issue?
I tested my master cyl. before I put it in by placing the reservoir and pouring some fluid in and when I pumped fluid squirted out of every orifice with great force, so I guess the mast. cyl. is fine.
