BEFORE BEDDING BRAKE PADS:
Please be aware that if you are using a new set of Circo brake pads on a used set of discs the bedding procedure will take longer as the pads must clean the material deposited on the disc and create a new friction material layer on it. This process can be accelerated if you resurface the brake discs in advance.
Make sure the disc surface is clean and grease free.
BRAKE PAD BEDDING:
Correct brake pad bedding procedure is essential to ensure maximum performance of the brake system on the car. Incorrect bedding can lead to excessive decrease in pad and disc life, as well as a general lack of performance. Correct bedding is achieved by slowly increasing the temperature on the pads and discs.
Potential issues such as overheating and glazing the friction surfaces should be avoided as much as possible, so it is important that the process is slow. Make sure the pads are correctly installed in the car.
Optional heat shield plates and left foot braking should not be used during the bedding procedure. Using 60 – 80% of pedal pressure, decrease the car speed from 80kph to 20kph.
Repeat the 7 – 9 times. (Do not come to a complete stop during this process as this will increase the temperature rapidly in the pads). Repeat the procedure from 1 20kph down to 80kph. Repeat the procedure once again this time from 120kph down to 20kph. Following each set of stops, allow some time without braking to cool the discs and pads before increasing brake force. After each set of stops you should feel an improvement in the brake performance. If you have access to temperature recording equipment, the brake temperature should be in the range of 400degC. Do a visual check on the discs to make sure the friction material of the pad is deposited homogeneously and if not, repeat the process. Once complete perform some high pressure braking to ensure the system is working correctly.
You may also want to re-bleed the brake fluid to ensure maximum results.
