General Bed-in Procedure
Warning: Only perform bed-in procedure in a safe and controlled environment without any obstructions. Signature Werks LLC. shall not be responsible for any damage, injury or death as a result of the bed-in procedure. Perform at your own risk. Start slowly at first with extra caution to make sure the brake system is functioning properly.
This is a general guideline and may not apply to all setups. Refer to the brake pad manufacturer’s instructions for exact guideline.
The purpose of bed-in procedure is to mate the brake pads with the rotors to ensure full contact, establish proper and consistent friction surface (transfer layer), and release the organic binding material (resin) held inside the pads during manufacturing process. With proper bed-in, optimum friction coefficient and wear can be achieved. It can also help minimize brake judder and rotor cracking or distortion due to thermal shock.
Bed-in of brake pads and rotors are technically different, although they are usually carried out as a combination of two different processes. During bed-in of pads, the organic binding material in the brake pads will be burnt and released, forming an air cushion between the brake pads and rotors. This process is referred to as "Green fade". Bed-in of different pads may require varied procedures, even if they are from the same manufacturer, as there are variations between friction materials and organic binding material (resin). The process is to bring the pads to a series of braking events at certain temperatures to stabilize them, and therefore providing stable friction coefficient after the bed-in process. For bed-in of rotors, it is important to ensure there is an even and consistent layer of pad material deposited onto the rotor surface to achieve optimum results.
NOTE: Avoid coming to a complete stop using the brakes. Avoid ABS Intervention. Do not drag brakes. Block off brake ducts if necessary to allow optimal bedding-in temperature.
Step 1: While the vehicle is stationary, pump the brakes to ensure a firm pedal.
Step 2: Drive the vehicle with utmost caution and ensure the brake system is working properly.
Step 3: Applying moderate brake pressure, make 6 to 10 stops to 5 MPH (8 KM/H) from approximately 30 to 35 MPH (48 KM/H to 56 KM/H). After each stop to 5 MPH (8 KM/H), immediately accelerate back up to speed and repeat the process.
Step 4: Make 2 to 3 stops to 5 MPH (8 KM/H) from approximately 40 to 45 MPH (64 KM/H to 72 KM/H). After each stop to 5 MPH (8 KM/H), immediately accelerate back up to speed and repeat the process.
Step 5: Cruise at 45+ MPH (72+ KM/H) for 10 minutes to allow the brake system to cool.
Step 6: Inspect the rotor visually. Make sure there is an even layer of wear on the entire rotor surface. Otherwise, repeat steps 3 to 6. Inspect brake rotors frequently to avoid overheating.
NOTE: During bedding-in, it is essential to allow the brakes to cool between different series of stops. Overheating the brakes during bedding-in may lead to glazing on the brake pads. Do not apply emergency brakes right after bedding-in as this may distort the rear rotors. At times the brakes may overheat quicker than expected. Inspect rotors frequently.
