67 Parisienne pulls left hard! Then works smoothly?!?!

Could this be a faulty master cylinder?
I installed new flex hoses and wheel cylinders on both front brakes today
Also installed new tires
Also installed new moog strut rod bushings
Both brakes were bled properly
Alignment was just completed
Car has never drove or stopped so nice!
Then all of a sudden next stop pulls left with a vengeance !!
Stomp the pedal out of frustration
Then perfect brakes again!!
Both front brakes are adjusted properly
I am chasing this problem and still not winning
Btw rears work perfect all the time
Thanks Greg

Just to add even more clarification
The shoes are not new but are in almost new condition
And have never been leaked on
Drums same story they are not new but in like new condition complete with silver caliper paint

Kinda thought when I put the brand new one on yesterday
And now the car still behaves the exact same????
I've been studying wondering about a residual valve???
I will admit I'm out of ideas
Thanks Greg

Disc brakes on the 67 ?.........might be a stuck caliper.
other possibilities collapsed brake hose,

Try switching the wheel cylinders from left to right. See if it goes the other way.

LOL, don't think that'll work as the front wheel cylinders are side specific.

I'd say either a faulty wheel cylinder or junction block.

Did you have the brake shoes right off when you replaced wheel cyl? There is a primary and secondary shoe, one is longer than the other. If you took them off,maybe replaced backwards? I would also pull drums and make sure all hardware is still on properly and no broken springs.

Sounds similar to a problem I had with my GMC, it was the brake line (flex line) to the wheel.

Thanks for all responses
I think I have figured this out
When I fixed each side
I took some emery cloth and scuffed the glaze off the shoes and drum
But I was in a hurry to finish up and did not scuff the other side
After about 50 stops things are even again
That's my theory .....

Good advice.
Look at my problem I had with complete rebuild.
