PowerBrake - X-Line 4x4 Big Brake Kit

  • Why should you consider upgrading the brakes on your 4x4?

    The rapid world-wide growth in modifying civilian 4x4 vehicles has created a significant need for well-engineered brake upgrade solutions. Overland enthusiasts are fitting roof-top tents, bull bars, long range fuel tanks, water tanks, additional battery systems, storage systems, additional spare wheels etc. All of these accessories significantly increase vehicle weight, which severely affects brake performance and results in increased stopping distances. Larger wheel and tyre packages are also becoming increasingly popular. These generally weigh a lot more than the factory-fitted wheels and tyres. This additional rotational mass again severely affects brake performance, leading to increased stopping distances. Many 4x4 enthusiasts are also tuning their vehicles, adding significant horsepower. More speed = more energy, resulting in increased brake temperatures and ultimately brake fade.


    What will a big brake kit do for you?

    Powerbrake X-Line 4x4 big brake kits are engineered from the ground up to be the ultimate brake upgrades available on the world market for 4x4 vehicles. They deliver significantly improved brake performance, reduce brake fade and vastly improve pedal feel and modulation. The performance gains achieved when fitting our big brake kits vastly outweigh the benefits that can be achieved by fitting upgraded, standard diameter discs and pads. Our civilian X-Line 4x4 big brake kits feature direct technology transfer from our R-Line off-road race brake systems that have been used by works race teams to win multiple FIA Cross Country World Championships as well the infamous Dakar Rally (which is regarded by many to be the most gruelling motorsport event on earth).


    Why choose Powerbrake?

    Our World Championship winning R-Line off-road race brake systems have proven themselves over a period of more than a decade in race conditions ranging from the scorching deserts of South America, the Middle East and Africa to the snow-covered forests of Northern Russia, to the fast gravel tracks of Mongolia in the hands of the world’s best off-road race car drivers. Our civilian X-Line 4x4 big brake kits were designed by the same team that designed our renowned R-Line off-road race systems and they are manufactured on the same state of-the-art equipment, in the same factory.

    All design features found in our civilian X-Line 4x4 big brake kits were directly developed through our extensive involvement at the highest levels of international off-road racing. The exact same technology, features and materials found in our Dakar Rally winning R-Line off-road race brake systems can be found in our civilian X-Line 4x4 big brake kits. When we claim “direct technology transfer” from our race to our civilian brake systems, we mean it. Every single feature in our X-Line 4x4 calipers can also be found in our current production R-line off-road race calipers that we supply to leading Dakar Rally teams.


    Are there different kit options?

    There are two offerings in our X-Line 4x4 big brake kit range (Stage-1 and Stage-2). Both kits feature the exact same X-Line 6-piston off-road calipers, caliper mounting brackets, high-performance brake pads and stainless steel braided brake lines. The difference between our Stage-1 and Stage-2 kits lies in the discs. Our Stage-1 kits include 350x34mm 1-piece discs with 48 x directional cooling vanes. Our Stage-2 kits include 345-395x34mm 2-piece, floating disc assemblies with 72 x directional cooling vanes. Our Stage-1 kits offer a massive step up in brake performance and cooling over the factory brakes at a competitive price point. Our Stage-2 kits take the disc technology a step further and are the closest that a civilian 4x4 owner can get to our World Championship and Dakar Rally winning off-road race brake systems.
