Choosing the right brake pad compound for the job is like choosing the right oil and tyre, a lot depends on the application and those conditions. Sometimes you want to stick with what you know, but sometimes the grass really is greener (blue in this case) on the other side. There are some compounds with a large operating window which are very forgiving to use, this is where Endless ME22 really shines.
Endless ME22 is a medium friction compound from the ENDLESS range of brake pads. As there is no industry standard testing for coefficients of friction, the friction details of 0.33-0.38µ is only relative to the other ENDLESS compounds. Some other manufacturers boast a higher friction coefficient number (µ), but ENDLESS ME22 still outperform these in terms of bite and friction.
Used in a range of cars and classes, Endless ME22 is used by drivers in the NZ’s 2KCup Series as well as the National Endurance Championships (NIERDC and SIERDC). Even for fast street use and track days Endless ME22 is a popular choice here. Our NZ 2015/16 Formula Ford champion also uses Endless ME22, showing its versatility and performance in a wide range of applications.
ME22 is based off the ENDLESS ME20 compound, but with more graphite in the recipe for extra disc lubrication. This extra graphite is the key for ME22’s performance, allowing the pad to work right from cold temperatures, but with the high temperature resistance like Endless ME20.
The key to long pad and disc life is having the pad to apply a friction layer onto the disc (for adhesive type frictions) in a wide range of conditions. Some harder sprint compounds with higher friction than Endless ME22 require heavier conditions; meaning that they need more brake temperature and more brake pressure for them to be happy and in the “zone”.
If any pad falls outside of this ideal operating condition, then the result will be sub-optimal performance and life. It’s not to say they won’t get the job done, but everyone’s looking for longer pad-life and the more cost-efficiency here the better.
Endless ME22 is a great pad to start with for cars that operate a factory braking system and factory brake booster. ME22 can be used with a sports tyre, right up to a slick tyre. Sometimes, if the driver wants a higher bite pad and is using a heavy car with a semi-slick or slick, compounds Endless N35S, N05U or S41S can be a more suitable choice.
As well as in our customers cars, we’ve used ME22 in our own Mitsubishi Evo 6 and the cold performance is great. It still needs the correct bed-in procedure to get that friction layer onto the disc – this will also keep noise and vibration to a minimum. Combined with a good quality disc and S-Four or RF650 brake fluid, you can really extract the most out of your braking system without needing to upgrade the calipers or disc size.
