How to make default aircraft brakes effective?

I do most of my testing using the ASOBO Default C-172.  In 2020 I can grease most landings and gracefully taxi to my parking spot.

In 2024 I am having a terrible time controlling the aircraft on the ground.  I landed the C0172 at 65 knots but a little long on KSEE RWY 27R which is 5300' at 359' above sea level.   I could not get the plane stopped and ran off the end of the runway.  It seemed like the brakes were ineffective.

Did a couple more test flights.  The foot brakes are sufficient to hold the plane still at full throttle while on the ground.  Pressing the CH Pro Pedals toe brakes move the toe brakes in the sim as I would expect.  The sim toe brakes reach the floor about 75% of the way thru the CH pedal stroke.

Landed carefully on the beginning of the piano keys on 27R at 60-knots.  Pulled throttle to idle and stood on the brakes.  5-seconds elapsed before the plane was below 50-knots and 2000' feet had gone by when I finally got the plane stopped.

Tried to accelerate from a standing stop while keeping the plane on the ground.  At 60-knots I pulled throttle to idle and depressed pedals to the floor.  Again, needed a little over 2,000' to get stopped.  Clear, Dry, 75F.

RW C-172 POH shows a stopping distance of 584' for the C-172 at sea level and 70-degrees. 

Several times while taxiing I have hit buildings because the brakes did not stop the Aircraft in time while moving at 25-mph.  

This problem does occur in other GA planes I have tested.

I have verified the response curves for the CH Pedal and find those curves to be linear with no dead spots or offsets.

What is happening here?
