Description
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 the big brake kits vastly outweigh the benefits that can be achieved by fitting upgraded, standard diameter discs and pads. The civilian X-Line 4x4 big brake kits feature direct technology transfer from the 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).
Included:
✔ X-Line billet 6-piston off-road calipers (featuring stainless steel pistons, internal fluid crossovers, protected bleed screws, internal wiper seals, ultra high-temp pressure seals, all stainless steel hardware, MTR max temp recording system, and pad anti-rattle springs).
✔ High-performance brake pads, pre-loaded into the calipers (featuring OE quality anti-squeal shims).
✔ Large 350x34mm 1-Piece slotted discs (featuring 48 x curved/directional cooling vanes per disc, MTR max temp recording system, and the proprietary black coating that ensures the fastest bed-in time).
✔ Billet caliper mounting brackets (featuring stainless steel thread inserts for the radial mount bolts for max service life).
✔ Stainless steel braided brake lines (featuring stainless steel end fittings, PVC protective cover, Teflon hose inner, and 32 x braid structure).
✔ All necessary mounting hardware for quick, easy bolt-on installation.
✔ Comprehensive fitment and bed-in instructions.
Fitment: 2005-2023 Toyota Tacoma
Features
Caliper Surface Finish: The X-Line 4x4 calipers are available in two finish options. Either a Red anodize (type-2) or a Dark Grey hard anodize (type-3). The anodize dyes used for the 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 the most durable finish and is the finish that Powerbrake uses on all of the off-road race calipers.
Caliper Logos: The logos and other markings are applied to the calipers using advanced laser technology. This creates a visually appealing contrast between the logo and the caliper color. The logos on the X-Line 4x4 calipers will not be damaged by heat, brake fluid, or solvents, as is the case with paint in-lay logos used by many of the competitors. Brake calipers operate in a very challenging environment. They are exposed to dirt, carbonized brake pad material, constantly fluctuating temperatures, and constantly changing environmental conditions. Powerbrake has focused on ensuring that the X-Line 4x4 brake calipers will remain to look good under the widest possible range of operating conditions.
Caliper Cross-Bolts: The high-tensile caliper cross-bolts used in the assembly of the X-Line 4x4 calipers are European sourced and coated with a silver zinc flake coating. This coating offers exceptional corrosion resistance while having no negative effect on bolt strength at all. The bolt positions of the X-Line 4x4 calipers are the result of extensive FEA analysis and deliver optimum caliper rigidity. The cross-bolts are inserted into the caliper from the inboard side resulting in maximum wheel clearance.
Caliper Pistons: Powerbrake X-Line 4x4 calipers all feature stainless steel pistons. Stainless steel is significantly more expensive to manufacture caliper pistons from than the aluminum pistons used by many of the competitors but the benefits are well worth the investment. Stainless steel transfers heat far slower than aluminum. The result is that stainless steel pistons slow the transfer of heat from the brake pads to the caliper seals and brake fluid, thereby reducing the chances of boiling brake fluid and also extending seal life. The caliper pistons are manufactured with a special grade of stainless steel that is more than twice as strong as regular 304-grade (in terms of yield and ultimate tensile strengths) while maintaining the same levels of corrosion resistance.
Internal Fluid Crossovers: The X-Line 4x4 calipers (like their Dakar-spec R-Line counterparts) feature internal fluid crossovers and hidden bleed screws for protection against damage from stone impacts. Every part of the X-Line 4x4 caliper is aimed at maximum usability and durability in tough off-road or 4x4 conditions.
Caliper Maximum Temperature Recording (MTR) System: All Powerbrake X-Line 4x4 calipers feature the MTR system. The system provides a permanent record of the maximum operating temperature reached by the caliper. Feedback from the R-Line race customers has been extremely positive with regards to the MTR system over the years. Powerbrake, therefore, decided to apply this same technology to the X-Line 4x4 calipers. Customers will really appreciate this feature as it provides valuable data in the support of brake fluid choice etc. The inclusion of a Max Temp Recording system on civilian big brake kit range at no extra charge is unique to Powerbrake on the world market.
Specs
Caliper Hardware: All other caliper hardware components (including pad retaining pins, bleed screws, and pad abutments) are manufactured from stainless steel to ensure the highest levels of corrosion resistance.
Discs: The 1-piece discs used in the (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. The discs feature 48 x curved, directional cooling vanes.
Disc Surface Coating: All the X-Line 4x4 disc rings are coated with a proprietary black surface coating.
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 the 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.
