EBC BRAKES - GPFA604/4HH GRAND PRIX (1 SET)

EBC BRAKES - GPFA604/4HH GRAND PRIX (1 SET)GPFAX is the new compound that replaces GPFA ONLY FOR RACE USE Highest performance friction level known NOT R90 street legal or TV tested Guaranteed for lifetime performance GPFAX Sintered Road Race Brake Pads have by far the highest known friction with a measurement between 0. 6 and 0. 7 and deliver the most amazing brake effect. Because of this factor, they are unsuitable for street use or for road tyres. Zero brake fade is guaranteed and the heat

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 that previous materials and should be good for 4-5 race events of 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.

Preparing your Race discs/rotors before using this Compound 
Many pads contain carbon particles some in high percentages and this leaves a grey glaze on rotors. This MUST be removed by fine abrasive paper or what is known as a Scratch Pad in the USA. Take care not to promote deep scratches on the rotor which will cause prolonged bed in times.

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 in to 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 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 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 as an old material even before you use it having absorbed water since originally opened.

Brake discs/Rotors for race use are important
