Do the coupes have one? Removing these IMO greatly improves pedal feel. This is the information i have gathered so far.
there is a thread that explains how to remove this device on a tiburon which is located inside the master cyl. (my lexus was near the firewall) Most modern cars are equipped with these somewhere.
although after further research the slave cyl/ throwout (concentric slave cylinder) "CSC" bearing design might have been hyundai way to add the delay in. but taking apart the master cyl should be simple and easy way to determine if there is a valve in there. also a cross reference in part number may reveal the answer.
