Wet Brakes

Is there a solution for braking in the wet on the highway?
I’ve done a few drives to our vacation property and a couple times it was quite wet. When applying brakes after some distance of non-breaking, I found the car pulling inconsistently either left or right on hard braking. I’ve been told a solution might be to “squeegee†the brakes ahead of applying .(I assume that means pumping the brakes lightly)
Aside from pulling over on the side of the highway every time it rains, are there another solutions out there?
Stock brakes and pads.
Thanks

Drum front brakes? I only experienced that with 4 wheel drum brakes on my 620 PU. Should not happen with discs.

That's a standard complaint of Glazed rotors
plus you could have a caliper/ piston binding
You can sand with 220 grit ,,,yeah turning really best but the limits stop you

Thanks
Greg: Discs on the front drums on the rear.
Red: I will have the front rotors checked.
Anything else?

What he said plus might be pads sticking in bracket.

What I used to do was to ride them to get them hot to steam off the moisture.

Thanks for the help. If it were sticky pistons or pads, wouldn’t I have problems of pulling left /right even in the dry?

Sorry, I should have looked to see what year car you had, knowing that only 1500s came with drums. I had drums all around in my '73 620, and they were terrible if soaked (like from driving through a deep puddle)... no brakes at all.
When dry I can occasionally get a little pull one way or another but it's slight... Yours must be a lot worse. As Red suggested, I'd start with a surfacing of the rotors, cleaning off any build up in the calipers etc, inspect/sand or replace the pads. Any opinion out there on slotted rotors? I know the slots are there for cooling, but I wonder what effect they may have on removing water...
