low fluid flow through driver front bleeder?
So was bleeding brakes and everything went fine till I got to the driver front. Basically the fluid drips out a rate of 1 drop every 2 seconds even if I am pumping the pedal. The front passenger had perfect fluid flow so I am not sure what is going on here. I even took the bleeder on the driver side all the way out. When braking the passenger side is the only pedal working and it causes the car to pull hard to the right. Is this the combination valve causing this? I was under the assumption both front brakes would be cut if it was engaged.
Also put a pressure bleeder on it and even at 20 lbs of pressure the flow does not change. When I do it to passenger the fluid comes shooting out.

Did you replace brake hoses? One could be damaged internally. Pinched/kinked line somewhere? Clogged bleeder? Clogged/rusted line?

Yup, the driver's side front rubber hose has failed.
The way they fail the most (MUCH more common than just bursting) is that where the fitting goes into the rubber part, the hole is VERY small; the fitting is steel; and it rusts due to moisture in the fluid. Eventually the rust builds up to the point that it blocks the hole. When this happens, the brakes pull HARD to the opposite side when you apply the brakes, and then sometimes, pull towards the bad side when you take your foot back off.
Since all however many hoses are on your car (at least 3) are made of the EXACT SAME material and have been immersed in the EXACT SAME fluid for the EXACT SAME length of time, they are most likely all in the EXACT SAME condition. Replace them all and flush the fluid until clear at all 4 corners. If you just replace the one hose that's failed just now, then you'll find yourself doing the same thing all over again next week, and the week after that, and maybe more. Kinda a waste of time, given how cheeeeeeep those hoses are to begin with.

Okay thanks. Literally did the passenger side not even 100 miles ago because it blew. I was going to do the driver side and was too lazy lmao. It does pull back to the driver side when I let off so that makes sense now. I was so confused on what was going on lol.
