Serpent 803187 Brake Pulley One-Way Set for 720 - Corner Control  [SER803187]

Upgrade braking on your 720 with Serpent 803187

The Serpent 803187 Brake Pulley Adaptor One-Way Set is made to boost confidence when braking on a 720 chassis. It smooths the transition between throttle and brake so you can carry speed into tighter turns.

What is in the kit

Inside the Serpent 803187 kit you will find a new 2-speed shaft, a one-way adaptor, a pulley adaptor that houses a one-way bearing, a replacement pulley, plus spacers and the required fasteners. The design lets the driven wheels decouple under braking, helping to control the car as rear tyres age or under changing grip.

Driving effects on track

The central one-way bearing disengages when off-throttle, allowing finer modulation of braking and improved turn-in. That behaviour helps deliver more consistent corner exits and reduces sudden rear traction loss.
