oh...
because the user manual of my car state if ABS+handbrake light 2gether = EBD problem..
my car is a Kia Rio JB btw...
haha...
when the speed sensor having some problem...
better take care a bit while driving lo...
esp dun do emergency brake...
coz my case oso same wif u, ABS warning light sometimes on sometimes off...
but the speed sensor dun function normally...
so 1 time i wan to do brake, just normal braking, while the ABS warning is off and ABS is functioning..
the speed sensor i think send wrong info to the ECU (maybe send info that i do hard braking) and the ABS suddenly activates, causes me almost fail to brake..
as ABS wrongly regulating my tyre braking (ABS system thinks they are doing the right thing based on the wrong signal send to them by ABS wheel speed sensor)...
mine is FR wheel sensor problem..
..
i at first oso feel don't like changing such small sensor for RM350++!!
but since that incident, i immediately go change the speed sensor...

What year is your RIO?
How did they diagnose and isolate that the issue is the Front Right sensor is the issue? Did you try to change the cables to the sensor first?
What was the exact error did you got if you use the computer tool to diagnose it?
I don't feel any issue on breaking for now.
