How to Balance Mini 4WD Brakes

Brake balance is the relationship between front and rear braking force, and it decides the attitude the car carries into a jump or banked section.

What imbalance looks like

Too much front brake pitches the nose down, so the car dives and can catch its front rollers. Too much rear lifts the nose, which is the classic setup for flying off the top of a jump.

Adjust with height, not just grade

Raising or lowering a sponge changes when it engages. Small height differences between front and rear are usually enough to shift balance without changing sponge grade at all.

Test on the section that matters

Balance only reveals itself on the feature it is set for. Run the car through the specific jump or bank repeatedly and watch its attitude, rather than judging from a full lap.

Downforce interacts

Aerodynamic and mass effects add to braking at speed. A balance that works at moderate pace may pitch differently when the car is running quickly, so test at race speed.
