After the Drum brake for Tamiya semi, a few gens of upgrade of my disc brake designs(I will post them up in these days), and the latest version is done.
Here's the finished pic:
and the road test video(I'm new to this forum, not sure if I shared correctly)

Some designing and building process pics:
The front space is very limited to fit the caliper and the mountings.
2 servos mount on the rear, 1for front, 1 for the rear, and the rear braking servo can be controlled independently to act like the handbrake. And that's the reason I choose XV02 chassis, it can be upgraded the central-diff. The lever on the servo horn is to balance the pulling force between 2 wheels.
the motor cover is for scure the "heat pipes" . Because the XV02 has the dust cover on the chassis may reduce the motor's cooling efficiency， so I designed the heat pipe colling system, and move the heat sink to the front.
During in the test, the temp outside is 20℃， after 15 mins running, the sensor on the motor cover indacated the temperature is 37， and when the car stopped, the temperature went up to 39 in less then 1 min, because the stopped car can't let the air run thrugh the heat sink. And also means that this cooling system is very efficent.
In fact there are also 2 cooling fans behind the heat sink , but the winter is comming, and I'm lazy, so I didn't connect it to the power supply.
Finally try to add some details. (not very good at the paint job, try to do it better next time)
