Brake Disc Rotor Replacement Instructions


The replacement of the Disc Rotor is necessary when the braking surfaces are deeply scored or the minimum thickness is below the one indicated on the rim of each disc rotor and in our catalogue. Please note that the minimum thickness measurement is a requirement by law and the machining of a disc rotor under this standard is not allowed.


You have purchased a black passivated rotor that eliminates the need to wash down any heavy-duty packing storage oil, used in the past.

To fit the Disc Rotor, the following operations must be applied accurately:

  1. Make sure that the surfaces of the coupling, either wheel hub or axle shaft, are clean without burrs and bruises.
  2. Check the run-out of the mounted Disc Rotor, which should not exceed 0.10mm.
  3. Rotate and clean the entire rotor contact surface with a warm soapy cloth to remove the easy wipe-off protectant and any contaminants transferred during fitment.


Always replace Disc Rotors in pairs to ensure a matched performance. Replacing only one Brake Disc Rotor can be dangerous, causing "out of balance" when the brakes are applied.

Always fit new brake pads with the new Disc Rotors.

Avoid excessive or high-speed braking until the Disc Rotor and pads have had a chance to "bed in" to avoid heat spots and the subsequent reduction in braking efficiency.

A recommended distance of 200 - 300 Kilometres is recommended for running-in purposes.


Brake pads and Brake Disc Rotors are safety-critical components and regular inspections are essential for your safety.


RDA & EBC Brakes Warranty period Rotors & Drums: 12 months or 20,000 km.

RDA will replace our product under warranty within the above stated period, however, there is NO WARRANTY expressed or implied for race or track use.

To claim warranty please return goods to the fitter/supplier who will need to complete the appropriate RDA paperwork detailing the reason for the warranty claim. At the same time, ensure you return the problem parts to enable us to complete further analysis.

Please note: No claim can be processed without the problem parts being returned and appropriate paperwork completed by the mechanic/distributor.

A correct bedding-in procedure is critical, as it will eliminate many issues and maximise brake performance.

The bedding-in process involves a gradual build-up of heat in the rotors and pad compound. This process will lay down a thin layer of transfer film onto the brake rotor surface, which reduces rotor surface roughness, cutting down on pad movement which reduces the chance of noise.

When bedding in a car, try to do it without stopping completely or braking longer than 3-5 seconds, allow a non-braking period between applications for cooling, and before parking at the conclusion of drive allow for an extended time without braking, to maximise cooling of brake components before the vehicle is stationary.


  1. Increase speed to 40km/h, put brakes on lightly reducing speed to 20km/h.
  2. Increase speed to 60km/h, put brakes on lightly reducing speed to 40km/h.
  3. Increase speed to 80km/h, put brakes on lightly reducing speed to 60km/h.
  4. Drive for a while at 60km/h letting brakes cool slightly.
  5. Apply brakes lightly at 60 reducing speed to 40km/h.
  6. Drive for a while at 40km/h letting brakes cool.
  7. Apply brakes lightly at 40km/h reducing speed to 20km/h.
  8. Increase speed slowly to 60km/h.
  9. Apply brakes lightly at 60km/h reducing speed to 40km/h.
  10. Increase speed to 60km/h, drive for a little while then apply brakes, reducing speed to 40km/h.
  11. Repeat previous step 2 more times.
  12. Drive for 2-3 minutes without braking to cool brake components before parking.
