Brake Pad Bedding Instructions

KNS Brakes Pad Bedding Instructions:

This is the process we use for both street and track customers. Consider the following when bedding. The purpose of bedding is to heat cycle the rotors, to burn off excess brake pad resins, and to apply a uniform brake pad transfer layer onto the rotor.

  1. Different cars and different sized brake pads and rotors will change the amount of time required to get the pads and rotors up to proper bedding temperature. Use your judgement.
  2. The bedding process mates the pad and rotor surfaces and generates the working 'transfer layer' that optimizes brake performance. Modify the process as needed to insure your safety and use your judgement.
  3. SAFETY is ALWAYS the most important consideration.

 

  1. Insure that you have a proper install and that your brakes function normally. Make sure your brakes work correctly before bedding
  2. Warm your brakes up by performing normal driving that includes some easy to moderate stops from normal speeds. You do not need to drag brakes and avoid coming to a complete stop with hot brakes.
  3. FIND A SAFE PLACE to perform several stops with minimal interruption.
  4. Perform 5-6 moderately hard stops from at or near highway speeds down to about 20 MPH.  You should not come to a complete stop.  Brake at a moderate level without engaging ABS.  You may smell brake pad and you may get some green fade so be prepared.
  5. Cool the brakes by driving for several minutes with no or minimal use of brakes.
  6. Repeat step #4 and 5 using the brakes harder but without engaging ABS.
  7. After the brakes have cooled look at your pads and rotors.  Expect to see a uniform and fine patina/gray film on the rotor and some white ash on the sides of the pads.  This is a general indication of good bedding.

Carbotech Bedding Instructions for AX-Series & XP-Series Compounds:

  1. All new brake pads require a bedding process, start this process by pumping your brakes a few times to assure proper installation. Once on track perform several moderate (medium) near stops (to a very slow rolling speed) to thoroughly warm up the pads and rotors. This should take 1-2 laps. This allows a thin layer of the pad material to be transferred into the micro-grooves of the rotor.
  2. After the pads/rotors are warm, perform a series of hard near stops (to a slow rolling speed) until some brake fade is felt. This process should take about 2-4 laps (depending on the track). Once this occurs, then stay off the brakes (as much as possible) and bring your car into the pits/paddock to completely cool. Do not lock the tires during this operation.
  3. Allow brake pads and/or rotors cool down to ambient temperatures; no less than 30 minutes. The total bedding procedure should not take more than 5-6 laps or about 10-15 minutes.

NOTE: The proper way to bed your brake pads and brake discs (rotors) is to bed them on the racetrack, NOT on the street.

Warning: Failure to properly bed in your pads could lead to friction material to chunk and break up resulting in poor pad performance and pad life. Improper bedding can also lead to overheating your pads and causing them to glaze over resulting in the car not being able to stop or slow properly.

 

What is the proper ways to bed brake rotors?

New discs (rotors) just like pads need to be bedded in. Proper bedding will increase the rotor life and make it more resistant to thermal cracking. Before installing the new brake discs (rotors), be sure to thoroughly clean discs with clean wipes and brake cleaner. By cleaning the disc surface you want to make sure you have completely removed any and all grease, surface residue, and debris that might contaminate or damage the brake pads. Once the discs (rotors) are installed on the vehicle perform the following procedure. Please note that you can bed new pads & discs (rotors) at the same time.

  1. Start out with several near stops for the first 1-2 laps, while gradually increasing your speed and brake force with every stop.
  2. Next, do another 1-2 laps at normal speed followed by a cool down lap. The gray coloration is the pad material depositing a transfer layer of material into the micro-grooves of the disc. This process is pinnacle in achieving the best performance and life out of the rotor.
  3. Then allow rotor(s) to completely cool down to ambient temperature.

Proper USED brake rotor bed in procedures:

  1. If rotors have been previously bedded with Carbotech brake pads, then bedding the rotors again is not necessary.
  2. If rotors were previously bedded using a different manufacturer’s brake pads; then it is strongly recommended that the used discs (rotors) be reconditioned/turned and meet minimum specification requirements.
  3. Start out with several near stops for the first 1-2 laps, while gradually increasing your speed and brake force with every stop.
  4. Next, do another 1-2 laps at normal speed followed by a cool down lap. The gray coloration is the pad material depositing a transfer layer of material into the micro-grooves of the rotor. This process is pinnacle in achieving the best performance and life out of the rotor.
  5. Then allow rotor(s) to completely cool down to ambient temperature.

NOTE: Brake pads should be checked regularly. If pads are wearing evenly, then the pads can be used almost down to the backing plate.

NOTE: Do not drag your brakes; meaning, do not continually drive around the track with applied pressure to your brake pedal. This does not bed brake pads and/or rotors properly. This can severely hurt the performance and life of your brake pads & rotors.

Hawk Street Brake Pad Bedding Instructions:

  1. After installing new brake pads, make 6 to 10 stops from approximately 30 to 35 MPH applying moderate pressure.
  2. Make an additional 2 to 3 hard stops from approximately 40 to 45 MPH.
  3. Do NOT drag the brakes!
  4. Allow 15 minutes for the brakes to cool down.
  5. After step 4 your brakes are ready to use.

Hawk Racing Brake Pad Bedding Instructions:

  1. After reaching medium speed engage brake pedal to slow car without coming to a complete stop. Release pedal quickly and do not drag brakes. Repeat four or five times.
  2. At higher speeds engage brake pedal to slow car without coming to a complete stop. Release pedal quickly and do not drag brakes. Repeat five times.
  3. At or near race speed engage brake pedal to slow car without coming to a complete stop. Release pedal quickly and do not drag brakes. Repeat three times. Allow a few seconds between brake engagements while car is in motion.
  4. Do not hold brake pedal. Park car for approximately 20 minutes or until brake rotors are completely cool to the touch.
  5. If during the above steps the brake pedal becomes soft or brake fade is noticed, park the car immediately for approximately 20 minutes. Do not hold brake pedal.

Important reminders:

  1. Do not attempt to use badly worn or damaged rotors with new brake pads.
  2. Do not drag brakes while car is moving during break-in procedure.
  3. Do not engage pedal while car is stopped at any time following the break-in procedure.
  4. Upon completing the procedure, allow the brake system to completely cool before racing.
  5. Applying the pedal a few times before the start of the race will allow the brake pads to heat up before attempting to reach race speeds.
  6. Clean a used rotor surface with fine sand paper or steel wool, rinse with water, dry and install before bedding new pads.
  7. Some forms of racing don't allow time for the proper break-in procedure to be performed. However, it is still very important to attempt to perform at least the core of the procedure: slow heat build up and complete cool down.
