Description

The Ksport Dualcomp 4 Piston 330mm Rear Big Brake Kit offers a sophisticated, bolt-on braking upgrade for select Mercedes-Benz S-Class vehicles (2000-2002 S55 AMG only). This system is engineered with a unique Dual Caliper setup, featuring four pistons per caliper. Two pistons handle the primary foot brake function, while the other two are dedicated to the handbrake, each operating on its own independent system. This design is Formula Drift legal and ideal for applications demanding enhanced braking control. The kit includes forged, monoblock aluminum calipers, lightweight two-piece rotors (available in slotted or cross-drilled options), SC5 Street pads for optimal street and occasional track performance with reduced dust and noise, and a polished Titanium handbrake cylinder and lever. The calipers are CNC machined from carbon steel and come standard in painted colors like orange, red, black, and yellow, with premium high-polish and custom color options available. Stainless steel braided brake lines are included, which resist expansion under pressure for a quicker pedal response and firmer pedal feel compared to stock rubber lines. Ksport Big Brake kits are built to order, requiring an estimated 4-6 weeks for production and delivery. It's crucial to confirm fitment for your specific vehicle before ordering. While Fitment Industries strives to ensure accurate compatibility information, they advise customers to always verify with their sales team, especially if the exact vehicle is not listed. If our sales team confirms fitment and the product does not fit, Fitment Industries will accept the return with no restocking fees, provided the item is in like-new condition.
