Could be the condition of the roads causing it. Calipers could be sticking.

speaking of,alot of times the rubber flex lines corrode from the inside out and you cant really tell by looking at them.that could probably cause this also.

It could be the valve or rubber hoses just ran all new steal lines from the master cylinder to front and back

No it won't be the proportioning valve, that only deals with front and rear, won't influence either left or right.

The rubber flex line is a good place to start if you cant find any other issues!...i had that problem with an 82 camaro I had.it actually locked the front driver side up!...this was any easy fix...to bad I went through new rotors,calipers,and pads before I was told about the lines!!...

Re: Brakes problem

Sometimes the rubber brake hoses can suffer a blowout internally on the inside liner and a flap of rubber will drop down preventing the fluid from returning properly. This could cause the problem you described.

At any rate replacing the rubber lines is always a good idea if you are not sure of their condition.
Maybe consider replacing them with braided lines which are much stronger and give a much better pedal feel.

I think he said he ran new steel lines.

Do you have new pads? If so did you seat them?

True. Thought he probably upgraded that too with braided.

Did you break the brakes in after the new pads? Heavy accel and heavy braking sessions?

Something could be lodged in the caliper between the piston and caliper. This will also cause the pads to wear at different rates. Maybe when you changed the pads you noticed one pad had more pad material left or one side was worn noticeably more the other. Example if the times it pulls it pulls right, maybe something is hindering the pistons in the left caliper. I've had an issue very similar to this and turned out small gravel was wedged in there. You don't have to be driving down dirt roads for this to happen.
Also braided brake lines are great, they give you good pressure and also help it be consistent. They will also give you you better feed back through the pedal to what the brakes are doing. Good luck
