Z17 Ceramic Brake Pad Technology

PowerStop’s Z17 formula is designed to improve upon traditional factory brake pads while maintaining smooth daily-driving characteristics.

Key Benefits

Low Dust Formula

The ceramic compound produces significantly less brake dust than many factory pads, helping keep wheels cleaner.

Quiet Operation

Chamfered pad edges, slotted surfaces, and rubberized shims reduce vibration and brake noise.

Fast Break-In

Thermal scorching helps accelerate the bedding process for consistent braking performance sooner after installation.

Reliable Stopping Power

The Z17 formula delivers predictable braking performance in both city and highway driving conditions.

OE Replacement Brake Rotors

The included rotors are engineered to restore original braking performance without introducing unnecessary noise or vibration.

Rotor Features

• Precision-machined braking surfaces

Unlike drilled and slotted performance rotors, these OE-style rotors focus on comfort, durability, and long-term dependability.
