Wrecked Duster Stocker

We bracket race & see a lot of brakes being used.
My Son prefers to use the "Womp Womp" method with the throttle to cut it in.
However, at a big money race last year, he had got on the brakes in the Semi & smoked the front tires.
He was warned about it.
He did the same thing in the final, got DQ.
Found out there was a problem in the braking system.
It killed two front runners with flat spots.

I use the same brakes on both cars & have no problem with the other one.
Traced it down to air in the system.

Just cost me about 350.00 for two new tires & a 1000.00 extra on prize money.
