Brakes - GPFAX447HH Grand Prix - EBC (1 Set)

GPFAX is the new compound that replaces GPFA 

The material quickly builds from an initial friction level of 0.6 ( which in itself is a massive brake friction level rarely achieved by any competitor material) up to a huge 0.7 with a minimum in-stop friction level of 0.65. This tiny fall off from 07 – 0.65 during braking would be almost undetectable by the rider allowing superb brake feedback and control at the lever and allowing feathering of the brake predictably and steadily throughout deceleration.

The new material also wears better and causes lower rotor/disc damage than previous materials and should be good for 4-5 race events of a typical 20-25 lap duration minimum. Pads should be discarded when less than 2.5 mm of friction material remains to avoid fluid vapor lock due to excess piston fluid volume.

This material contains no toxic lead nickel or zinc which is a trick used by our competitors to ramp up friction levels the cheap way.

Correct usage!

Bedding in your new brake pads

After installing the pads ride the bike for 2 laps very gently applying the brakes well in advance of where you wish to stop at speeds not exceeding 80 MPH.

Proceed a further 2-3 laps gradually increasing the brake load until you feel the pads become stable and predictable.

Bedding into worn or distorted discs/rotors will be dramatically longer.

Inspect pads every Race for wear on EACH pad and replace when any single pad is down to 2.5 mm or lever becomes spongy. Different brake systems respond differently and have differing amounts of fluid in their piston chambers and the time for an ideal replacement of the pads due to loss of brake feel can only be assessed by the individual rider and bike

Brake fluid considerations

Old brake fluid affects the sponge and brake feel. Most brake fluids are Glycol based and over time their hygroscopic nature means they will absorb moisture even through the brake lines. As amazing as this sounds it does happen and fluids can contain as much as 12% water by volume in worst cases.

It is highly advised to replace brake fluid every 6-8 race events as a minimum with a high wet boiling point fluid such as Maxima Race fluid. Use only fluids from a sealed container, never from a bulk can or drum as in this storage condition the fluid will act like an old material even before you use it having absorbed water since originally opened.
