Big Brake Kit Details

• Caliper Construction: 6-piston calipers machined from solid billet. All of our championship-winning X-Line and R-Line race calipers are machined from high-grade aerospace aluminum billets, and we’ve chosen to manufacture the X-Line 4x4 range from the same material. Machining from billet is admittedly an expensive way to manufacture calipers but it results in a finished product that exhibits exceptional levels of strength and rigidity.
• Caliper Surface Finish: Either a Red anodize (type-2) or a Dark Grey hard anodize (type-3). The anodize dyes used for our Red finish have been carefully selected to offer the maximum UV and temperature resistance to ensure long-term color retention. The Dark Grey hard anodize is our most durable finish and is the finish that we use on all of our R-Line off-road race calipers.
• Caliper Logos: Advanced laser etching technology
• Caliper Cross-Bolts: Silver zinc flake coating through bolts
• Caliper Pistons: 6-pistons
• Internal Fluid Crossovers: Hidden bleed screws for protection against damage from stone impacts
• Caliper Maximum Temperature Recording (MTR) System: All Powerbrake X-Line 4x4 calipers feature our MTR system. The system provides a permanent record of the maximum operating temperature reached by the caliper.
• Caliper Hardware: Manufactured from stainless steel
• Discs (Rotors): The 1-piece discs used in our (Stage-1) X-Line 4x4 big brake kits are cast from a proprietary high-carbon cast iron alloy that provides excellent durability and stability under the high thermal loads experienced under fast-street or off-road driving.
• Disc Surface Coating: All our X-Line 4x4 disc rings are coated with a proprietary black surface coating. The coating is able to withstand extremely high temperatures and is flexible enough to expand and contract without flaking or peeling off of the disc surface during the constant thermal expansion and contraction cycles experienced by the brake disc.
• Disc Maximum Temperature Recording (MTR) System: Each single-change paint color (4-levels: Blue, Green, Orange, and Pink) changes to white when a specific temperature is reached, thereby providing a record of the peak operating temperature of the disc.
• Caliper Mounting Brackets: X-Line 4x4 caliper mounting brackets are machined from billet aircraft-grade aluminum alloy, FEA enhanced for strength and rigidity, and (type-3) hard anodized.
• Brake Lines: The brake lines included with our X-Line 4x4 big brake kits feature an extruded Teflon inner lining that is highly resistant to the aggressive chemical properties of modern brake fluids, as well as being able to handle far higher temperatures than rubber.
• Brake Pads: The Powerbrake X-Line 4x4 calipers are designed around a pad profile which is available in a wide range of brake pad compounds from most pad manufacturers worldwide.
