X-Line Big Brake Kit Range Design Philosophy

For 2016 Powerbrake has launched our next generation X-Line big brake kit range. Powerbrake X-Line calipers are true race calipers that can also be used in long-term street and track day applications as a result of a number of additional design features that have been incorporated into the caliper designs. The X-Line big brake kit concept is to supply customers with a crossover product line that (when fitted with the appropriate pad compound for the intended application) can be used over a wide range of enthusiast and race applications including fast-road, track day and full race. To be clear - Powerbrake X-Line calipers are true race products. Machined from solid billet aerospace grade aluminum, these calipers feature ultra-rigid FEA enhanced designs, scalloped stainless steel pistons and type-3 mil-spec hard anodised finish typically only found in high-level works race calipers. The addition of internal wiper seals and all stainless steel hardware (bleed screws, tube nuts, pad retaining pins, abutment plates etc) further enhances the long term durability and service life of our X-Line calipers under every day street driving conditions. The result is one of the most versatile big brake kit ranges on the world market. Powerbrake X-Line = Works-level race calipers that can also be used for long-term street and track day applications (when fitted with appropriate pads).

Powerbrake (X4ES) Compact 4-piston X-Line caliper

Features

Compact 4-piston race caliper.

Design is FEA optimised for maximum strength and rigidity.

Machined from the highest quality aerospace grade aluminium billets resulting in optimal strength and rigidity.

Caliper bodies are mil-spec type-3 hard anodised for max durability and wear resistance.

Stainless steel pistons ensure maximum durability and significantly reduce heat transfer rate to seals and brake fluid (when compared to the aluminium pistons used by many of our competitors).

Pistons are scalloped to allow super-heated air to escape resulting in reduced operating temps and hand polished to a mirror finish on the outside diameter to assist in achieving maximum seal life.

Ultra-high temperature pressure seals and internal wiper seals ensure maximum durability and service life.

High-tensile caliper cross-bolts are manufactured in Europe and coated with a proprietary anti-corrosion coating that provides unmatched corrosion resistance and does not negatively affect bolt strength at all.

Seamless CuNi fluid crossover tubes (not pictured in the renders below) provide maximum corrosion resistance and unmatched resistance to vibration-related issues (that can affect seamed tubes used by many of our competitors).

All other caliper hardware (bleed screws, tube nuts, pad retaining pins and pad abutment plates) are stainless steel for maximum corrosion resistance.

Maximum Temperature Recording (MTR) system provides a permanent record of the peak operating temperatures reached by the calipers during use.

All logos and serial numbers are laser-etched onto the calipers which makes them impervious to damage from brake cleaners and solvents (as is the case with the painted logos used by many of our competitors).

Pad Profile

The pad profile chosen for X4ES race caliper is available in the complete range of Powerbrake street, track day and race pads compounds. The profile is also available from most high-performance and race pad manufacturers world-wide.

Rotors - The disc friction rings used in our X-Line disc assemblies are cast from a proprietary high-carbon cast iron alloy cast in Europe that provides excellent durability and stability under the high thermal loads experienced during race, track day andamp; fast road driving. The discs feature our curved, directional, staggered cooling vane design that increases cooling vane surface area for optimal cooling.
