2 dr 2015 JK sport with 33 x 12.5 x 15 general tire grabbers. 52,000km. Pulling out of a church I had to stop quicky as a car came speeding around a bend that I didn't see..my brakes didn't work like normal and felt very "floaty" Is best way I can describe. They worked very slowly and I almost didn't stop. It did this the next time I tried to brake again. After parking for a hour and driving again all seems normal and brake are responsive. Has anyone else experienced this before?
