                             Brake Pad Bedding and Rotor Seasoning


Seasoning Rotors:

If you have zinc plated rotors you need to drive the vehicle for a few days before seasoning of the rotors can actually begin.  
It's necessary to wear that coating off.  Do not make any hard or aggressive stops.  Drive like your Grandmother would
running to the supermarket, (painful, I know...).  The idea is to gradually add heat to the rotors and allow them to heat cycle
over time.  Even if you don't have the zinc coating, this process will yield good results.  The following is recommended by Baer
Racing.

  • Find a location that will allow you to brake at your leisure without traffic and pedestrians.
  • Make 4 normal driving stops from 60-70 mph to get the brakes warm.
  • Make 4 medium / 50% stops from 60 mph to 15 mph.
  • Follow this with 5-10 minutes of highway driving to allow the brakes to cool.  Do your best to stay off the brakes.
  • Make 4 medium / 75% stops from 60 mph to 15 mph.
  • Again, follow up with 10 minutes of highway driving to cool the brakes.
  • Allow the brakes to completely cool.  Overnight if possible.
  • Repeat ALL but the last step to bring everything up to temperature.
  • Make 6 hard stops from 60 mph to 15 mph without locking up the brakes.
  • Drive for 10 minutes on the freeway once again and let the car completely cool (overnight if possible).  Don't forget to  
    stay off the brakes during this cool down period.
  • You're done.  Go to the Brake Bedding procedures...


Bedding Brake Pads:

Bedding the brake pads will allow the pad to make the proper contact with the rotor.  "The friction material in semi-metallic
pads is held together by an organic binder.  ....As the pads get hot, the binder boils, and burns, from the top surface of the
pad.  Once this burning or “Bedding” takes place the friction material makes proper contact with the rotor," (Baer Brake
Systems).  Carbon metallic pads will deposit a layer of carbon on the rotor to reach maximum efficiency.  It is not
recommended to switch from a carbon metallic pad to a semi-metallic pad.  The semi-metallic pad will have to eat through the
carbon before the brakes will grab correctly.  If you have semi-metallic pads and have not been aggressive with them in
some time, it may be necessary to repeat the bedding process.

  • Make 4 light to medium stops from 60 mph to 10 mph to warm the brakes.
  • Make 2 hard stops pending wheel lockup from 60 mph to 5 mph.
  • Drive for 10 minutes on the freeway to cool the brakes.
  • Make 3 light stops.
  • Make 8 hard stops pending wheel lockup from 65 mph to 5 mph.
  • Drive for 10 minutes on the freeway to cool the brakes.
  • Your done.  Go have fun....
