UM Big Block Modified

The Big Block Modified's braking system is fundamentally different from most race cars, operating as a setup tool rather than a primary speed control mechanism on dirt. The brake pressure bias adjustment distributes braking force between front and rear axles, while the RF brake connection toggle offers a unique handling characteristic—disconnecting the right front brake generates a yaw moment under braking that aids turn-in response at the cost of stability. This unusual configuration reflects dirt oval racing priorities where rotation matters more than pure deceleration.

Brake bias adjustments interact directly with corner entry balance. Higher front bias increases stability but reduces turn-in sharpness, making the car push into corners. Lower front bias or disconnecting the right front brake improves rotation but requires precise throttle control to avoid instability. On high-moisture tracks, disconnecting the RF brake often works well, while slick conditions typically benefit from four-wheel braking to maintain control during the critical entry phase.

The car's minimal braking zones and single-gear direct drive mean you'll use brakes primarily for corner entry setup rather than sustained deceleration. Focus on smooth, progressive brake application to avoid upsetting the car's delicate weight balance. The large suspension travel and aggressive roll characteristics make abrupt braking inputs particularly destabilizing, especially when transitioning from throttle to brake mid-corner.
