While we do our best to keep inventory in stock, some pads may need to be special ordered from Japan.  Delivery times can vary from 2 weeks to 4+ weeks depending on stocking location and inventory.

ME20 is a semi-metallic compound, developed for racing and rally. It is a step up in initial bite and is more “straight-forward” with regards to brake power. Originally developed for BTCC Super Touring Cars where you have high traction afforded by suspension setup and tire compounds. The pedal feel and brake power is excellent and equal across the speed range with an easy modulation in all instances. With the ME20 it is possible to perform very hard and late braking into corners. As with the friction and bite the ME20 is a step up in heat resistance compared to the ME22 and it has shown a very good stabile brake performance at high disc temperatures over 650 °C.

The wear characteristics of both pads and discs are low, and for cold weather and wet conditions it retains the same excellent resistance to water fade. The ME20 also reaches operating temperature very fast, like all other Endless compounds.

    Info corner - How friction materials work:

    Brakes convert the kinetic energy of a moving vehicle into heat. The simplest way for a brake system to absorb kinetic energy is to break mollecular bonds in the rubbing surfaces of the brake pads and rotor. This is called "abrasive friction" (think sand paper).  As the pads act on the rotor as an abrasive, both the rotor and pads wear agressivly, turning the pad and rotor into brake dust.

    A more sophisticated way to absorb kinetic energy is "adhesive friction"  (think sticky).  In order to achieve adhesive friction, a proper bedding procedure must used to heat up the brake pads enough to transfer/smear a thin film of friction material from the brake pad to the surface of the rotor.  Typically a properly bedded pad/rotor will exibit a darker hue on the rotor surface (a blueish look) which is actually a thin layer of brake pad material.  As the rotor is squeezed between the cold rotor and pad, heat generated causes the thin layer of pad material to become sticky.  Now instead of grinding the pad away at the surface of the rotor, the pad actually drags on the sticky layer of material on the surface (like dragging a post-it across a table).  Adhesive friction relies on the surface properties of the friction material and transfer film buildup.  The pads wear relatively slowly (just enough to keep a supply of adhesive materials at the surface) as they are not being ground away like typical brake pads. While in some ways more finicky than standard abrasive-type pads (requiring a maintained transfer layer to work optimally), they are in nearly every way superior from lower brake dust, to less pad and rotor wear.
