Improve the looks and performance of your brake system with our HALO XD Series (cross drilled) brake discs, when it comes to stopping your vehicle it’s the job of the brake disc to convert kinetic energy into heat, Cross Drilled brake discs are superior when it comes to improved cooling, so choosing a brake disc is an important step in improving your brake system, HALO brake discs are carefully chosen for their quality and value to provide a long life and optimum performance combined with value for money.

Road and Fast Road 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, for this reason we don't advise using the cross drilled brake discs for track use as they have a tendency to crack between the drillings.

  • 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 

Post Fitment

After fitment and road-testing re-check the wheel torque, to ensure proper even torque.

All HALO Sport brake discs are supplied as an axle set unless otherwise stated
