Running two 2019 rivals with jr drivers. Both run the chassis supplied heel risers. The pressure they place on the pedal in an avoidance situation such as a spin out in front of them causes the riser to bend up, this pushes the pedal away from them. Anyone come up with good solutions for this or even experienced it? When we got these they were set up and assembled for us by a reputable dealer who did out last karts as well. Kids went out on them and said they were hard to stop. I assumed that they were just not used to the new master cylinder/ brake pressure. Saturday one completely lost brakes and I had to catch him at the end... that sucked. I found no leaks, emptied all fluid from the master cylinder lines and caliper, installed new dot five brake fluid, and bled. Brakes seem to be OK now but I just don’t understand what failed. Fluid was full. It almost had to be air.
