Powerbrake X-Line Big Brake Kit Stage 1 Jeep Gladiator JT 2019-on Front

Powerbrake X-Line Big Brake Kits were developed to address a serious problem with the braking efficacy of modern 4WD vehicles. When loaded with upgrades such as vehicle protection, overlanding gear or heavy freight loads, braking efficiency suffers and stopping distances can increase dramatically. Using Dakar Rally-derived technology and manufacturing processes, Powerbrake are able to offer the ultimate in braking performance and component longevity.

The rapid worldwide growth in popularity of modifying civilian 4×4 vehicles for overland travel has created a need for significant brake upgrade solutions. Steel bumpers, overland equipment; winches, spare wheels and other items, all add up to what is often a significant load increase. These increases in accessory weight severely affect braking performance, resulting in longer stopping distances. Large wheel and tyre packages are also becoming increasingly popular and these generally weigh far more than factory-fitted wheels and tyres. This additional rotational weight further affects brake performance, leading to increased brake fade and altered stoping distances.

As a result, 4×4 enthusiasts are requesting ‘big brake kits’ that include high grade rotors, multi-piston calipers, high-performance brake pads, stainless steel uprated brake lines, etc. These bespoke kits significantly improve braking performance, while reducing brake fade and improving stopping distances on 4×4 vehicles. Since 2004, Powerbrake engineers have built these kits around their renowned multi-piston off-road race caliper. The fluid crossovers and hidden bleed screws of this caliper make it perfectly suited to heavy off-road use. When paired with high spec discs and pads, the full potential of the multi-pot calipers is released and optimal braking performance can be achieved. Powerbrake X-Line kits bring proven race technology to your 4×4 vehicle.

Powerbrake Stage 1 Big Brake Kits are a significant upgrade compared to stock brakes, and top-spec components are used throughout. From 1-piece high-carbon coated discs with temerpature indicators to high carbon pads and stainless steel brake lines, this kit brings race technology to your braking with direct-fit parts and full instructions provided.

• 6-pot calipers machined from aerospace aluminium billet
• Stainless steel caliper pistons
• High-carbon alloy discs and pads
• Reduced stopping distances in both wet and dry conditions
