2024 models brake fade, which could be relevant if you've been practising circuits and have heated up your brakes.
One of the debug tools in Dev Mode shows brake effectiveness and live values - check the 'Aircraft' > 'Wheels' overlay.
The yellow lines coming from the wheels show the force direction and the length indicates the amount of force.

Here, the aircraft is turning so there is a sideways force. When braking, the force is backwards etc.
With the Duke, the force lines from the main wheels are always vertical, which might be an indicator of a slightly different implementation in the sim, as the handling otherwise feels correct. I'm not meaning to pick at Nick's incredible work, so have no idea what this difference actually means.
Here you see a high force on the left wheel and small force on the right wheel, due to a tight right turn (but the lines do not 'lean' to show the sideways forces as for the C152):

Finally, the overlay window shows brake temperatures and effectiveness. As they get hot, the effectiveness reduces. Here's a sample after taxying around with my left brake on:

I'm applying 100% brakes but am only getting 70% effectiveness due to the brakes being 229°C!
Also, since you asked, the overlay shows the surface type under each wheel and it changes dynamically along with the lateral and longitudinal forces:

So while I can't give you any definitive answers, I can perhaps give you a way to check/test your situations and understand what might be happening. It's fun to look under the hood and see the magic happening
