HALO J Hook Slotted Brake Discs
Improve the looks and performance of your brake system with these Halo Performance J Hook brake discs, when it comes to stopping your vehicle it’s the job of the brake disc to convert kinetic energy into heat, so choosing a brake disc is an important step in improving your brake system, Halo Performance brake discs are carefully chosen for the quality and value to provide a long life and optimum performance.
Road and Track Use
HALO brake discs perform on the road and on the track but as you can imagine the temperatures achieved on the track are usually much higher than seen under normal road use, if using on the track it’s important that extra care is taken during fitment and post fitment.
- Ensure the hubs are cleaned before fitment
- Ensure there is no excess free play in wheel bearings
- Ensure the brake discs are running true before use by measuring run-out
- Ensure the brake caliper pistons and slides are move freely checking slides for wear
- Ensure tightening torques are adhered too
After fitment and road-testing re-check the wheel torque, this is especially important when using on track use after several laps, as the heat absorbed by the brake discs will transmit through to the wheel hub and wheel, this causes your components to expand and may lead to reduced wheel tightening torque. This will lead to brake vibrations when braking and may permanently damage your brake discs and ruin your track day enjoyment. Please note however we do not offer warranty for use on track.
EBC Brakes RPX Brake Pads
Designed for vehicles driven hard on track, RP-X™ possesses a high friction level of 0.55 between 0 – 850°C and achieves 100% brake effect from cold. This makes RP-X™ an excellent choice for sprint racing or hill climb events, where full brake performance is essential without requiring any ‘warming up’, but also makes RP-X™ well suited to any type of circuit use where a high initial bite and powerful brake response is desirable.
