Why Jeep Owners Like Complete Brake Kits

Many Wrangler owners use their vehicles for a mix of:

• Daily commuting
• Highway travel
• Camping trips
• Light towing
• Off-road exploration

Replacing the entire brake system at once helps ensure balanced braking performance and consistent wear across all four corners.

Z17 Ceramic Brake Pad Technology

PowerStop’s Z17 ceramic brake pads are designed to deliver quiet and reliable braking performance.

Key Benefits

• Low brake dust output
• Quiet operation
• Smooth pedal feel
• Reliable stopping power
• Long service life
• Improved wheel cleanliness

For Wrangler owners running aftermarket wheels, reducing brake dust is always a welcome bonus.

Thermal-Scorched Brake Pads

The included Z17 pads are thermal scorched during manufacturing.

Benefits Include

• Faster break-in
• Improved bedding process
• Consistent friction characteristics
• Better initial stopping performance

This helps the braking system achieve optimal performance sooner after installation.

OE-Style Replacement Rotors

The Autospecialty replacement rotors included in the KOE7939 kit are designed to restore original braking performance.

Rotor Features

• Precision-machined surfaces
• OE-style fitment
• Balanced construction
• Smooth braking operation
• Factory-like pedal feel

These are not performance rotors, and that’s intentional. Most Wrangler owners simply want dependable braking that feels like new again.

Low Dust and Quiet Performance

One of the biggest reasons drivers choose ceramic brake pads is reduced maintenance.

Advantages

• Less brake dust accumulation
• Cleaner wheels
• Reduced brake squeal
• Improved driving comfort
• Lower maintenance requirements

Combined with the included rubberized shims, the result is a quieter braking experience than many factory systems.
