'81 Toy Pickup. front drivers brake, vibrates with respect to vehicle speed when brakes applied. pulls to left badly also. replaced bearings, which fixed prob for a while, then gradually started happening again. then replaced bearings and rotor. problem stopped for a while, now gradually started happening again. need to go on road trip and concerned about safety. any ideas besides taking it into a shop?

The Vibration you describe certainly sounds like you DO have at least one warped rotor if not both. Does the steering wheel shake/shimmy in direct correlation of the brakes vibrating? If so, then that another indication you have a warped rotor(s) on a front wheel.
What concerns me is that your truck PULLS badly to left when applying the brakes. This would indicate that the right side front brake is not working properly. Could be as simple as a bound/rusted caliper where it mounts to the wheels' knuckle. Or it could be a frozen caliper on the RH side in which case replacement would likely be neccesary. It could also be a bad or kinked brake hose on that RH side. Those are the most common reasons I've seen in my experience.
I would speculate that when you replaced the bearings and then the rotors you temporarily dislodged the caliper allowing it to properly float for awhile until it rusts up again on it's slide or moved back into a position that is holding it from moving further again. Note: most calipers are termed 'floating' calipers as a way to describe the way they function - they must be able to slide or 'float' back and forth towards the rotors.
Another possibility is that your LEFT caliper has a bad piston in it that is being held out and not able to slide back into the caliper. If this were the case though you would see advanced wear of the front left brake pads as compared to the right front pads. Another thing could be a bad LEFT front brake hose that is not allowing the brake fluid pressure to be relieved in that LEFT caliper - again advanced pad wear would likely be evidence of this.
With all that being said and getting you completely confused: I would think that replacing BOTH of your front calipers and pads would allieviate your troubles for good. Its a great idea to have your rotors resurfaced at the same time, assuming they are still thick enough to be machined.
SideNote: Also be sure that your two front rotors are machined to within 10 Thousandsth of an inch of each other. In other words, they have to be very, very close the same thickness as each other.

I would first blame the problem on the rotor but you said you replaced it. Also you can check the condition of the brake caliper along with the brake pads. Most places give free brake checks. You could still have a bad rotor. Rotors sometimes warp after riding through a puddle of water when the rotors are hot from applying brakes in traffic or down hills.

iciness tires have a extra aggressive grip, so any problem is magnified even as it comes time to computer screen the brakes. extra probable that's the front braking equipment. probable warped rotors from choppy braking and warm temperature enhance. go get a the front brake pastime and performance the backs adjusted. Get the most acceptable pads you are able to have the funds for. Midas many times does a competent pastime even as it is composed of that. do not forget you want a the front end alignment once you adjust tires, highly if it truly is been a three hundred and sixty 5 days or extra because the most suitable one...reliable success.

Change the brakes

Check for uneven tire wear. It sounds like your alignment, but don't take it from me...you really should go see a mechanic.
