Recommended Bedding Procedures for Mintex F Series Racing Friction Materials

Whilst the entire line of Mintex Racing Friction has received a Pre-Burnishing procedure at our factory, there still will be a bedding requirement. Conditioning of discs and establishing the friction to disc interface are the primary reasons for this procedure. Prior to bedding ensure that these few simple rules are followed.

Never place or lay the brake pad face down on anything. Contamination from oil or oil like substances will seriously degrade the friction performance.

Always bed new pads on used rotors and new rotors with used pads. Do not use new pads on any disc that is grooved or is not in good condition. Follow the disc manufacturers recommended procedure on bedding in new discs.

It is best to not start a race with virgin discs or pads and never start a race with both, Always use the warm up sessions to bed discs and pads.

If using new discs ensure that they are properly cleaned with approved cleaners so as to remove any machining fluid or packing (preservation) oil.

Always inspect all caliper piston seals to ensure that they are in good condition and that they are leak free.

A piston seal is relatively inexpensive so if in doubt replace them between every race. The failure of a seal in a race could not only cause you to DNF but would create instability with possible disastrous outcomes.

In addition to seals it is essential to bleed the brakes and replace the brake fluid often. Hydraulic brake fluid is very susceptible to moisture absorption. The higher the moisture contents the lower the boiling point of the fluid. If you are competing in an environment where it is raining or there is high humidity, replace the fluid between each session. If your brake fluid is brown or darker replace it regardless of how recently you put it into the system. Tracks that are known for high brake temperatures will require frequent fluid changes.

Finally before the wheels go back on the car ensure that all the brake bleeder screws are secure and leak free.

To have a brake bleeder screw loosen up has been the cause of some severe incidents and all could have been prevented with a little attention to detail.

After the wheels are placed back on the car ensure the nuts are properly torqued into place. This is very critical for stock/Group N classes that are required to be equipped with the non-floating (solid) disc and bell. If the wheel nuts are not torqued properly the disc becomes susceptible to warping under high temperatures and loads.
