Do it several times and personally a nice 100+ to 20 will really do the trick nicely. You might be shocked how the brakes bite after you do that!! Burns all the nasty crap off! I have a favorite exit ramp I come into at 75-80 at least once a week. Its downhill with a hard left at the bottom. Needless to say waiting till ~200 ft is all that is needed! Threshold braking is typically the single biggest weakness in street driver's esp in the age of ABS. BTW have you tried to find ABS yet?
