Product Description

The PowerStop K5399 Z23 Evolution Sport Rear Brake Kit is a rear brake upgrade for the 2004-2008 Acura TL and 2003-2011 Honda Element. Both the TL Base and Type-S are covered - the rear rotor is the same regardless of whether your TL has single-piston or 4-piston aluminum front calipers. The Z23 Carbon-Fiber Ceramic pads deliver improved stopping power and significantly less dust than factory pads, paired with drilled and slotted solid rear rotors for improved heat management.

G3000 iron rotors are precision-cast to OE tolerances for a direct bolt-on fit at the rear axle with no modifications required. For the matching front kit, TL owners with 4-piston aluminum front calipers should see PowerStop K2718; TL owners with single-piston front calipers should see PowerStop K2298. Honda Element owners should pair with K2385 for the front axle. For the Z26 Street Warrior version of this rear kit, see K5399-26.
