Sudden dangerous braking pull.
So my buddy and I were coming home after dropping off a bridgeport mill with a JLG drop deck trailer. Towed out there just dandy but coming back she generated a dangerous pull to the left (lane switching variety).
A little back story is I recently did rotors, pads and repacked the bearings. I also bleed out the rear and adjusted the drums and had a lovely firm pedal.
So i get her home, drop the trailer and head to the parts store. I figure the calipers or brake hoses are causing the issue. Replaced those, bleed, bleed, bleed. Take her out for a spin (still a lovely firm pedal) and the **** thing still likes to switch lanes with the brake pedal. Left rotor feels warmer than the right so I am assuming it is still in the brake system. I did not replace the center or hard lines FYI.
Im at a loss since it just came out of the blue. No lead up or nothing, just BAMN, welcome to the next lane to the left...
Any Suggestions? This is also a stock 1992 w250, not my old green one.

Do you have a laser temp gun or what ever you call those things? I find them handy to isolate the hot spots or at least see if it is the hub or the rotor etc. But since it happens only at braking I should think it is somewhere in that system and not bearings etc.
Hard line not pinched or bent? Does it correct itself when you let your foot off the pedal or does it still pull? Something on the disc that is making it grab?

Check the steering gear mounting plate for cracks. Loose suspension parts too.

Drivers side bushing was split as it should be but worn and deformed...Also not the problem. Replaced both as they were cheap and figure it would not hurt.
Replaced the passenger hardline with some creative bending, finally using the flaring tool from the bottom of the junk drawer. Bled, chased a leak and drove down the road. Step on the breaks and the **** thing pulled again, though not quite as violent. A little grumpy I tear through the neighborhood gassing and braking hard. Notice the pull diminishing. Keep doing it down a couple of grades and boom, started stoping straight and hard. I will say the brakes got rather toasty during the process but something happened for sure. Brakes are frighteningly strong now. Open to speculation, possibly poor quality brake pads seating? No clue but I'm going to put a couple miles on her tomorrow and drop off the trailer, bleed it one more time and then call it good... What a way to ruin a nice weekend.

I'm sure he meant that, yes.
One of my front axle joints froze up on one axis, and whenever I made a turn, the truck refused to return to a straight driving direction. Hubs locked or,not
Not sure if the axle joint being bad would cause a hard pull, as its not being tweaked driving straight.
