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 grueling motorsport event on earth).
