What’s Included?

Unlike many brake packages that only include front components, this Detroit Axle kit covers the entire vehicle.

Package Contents

• 2 Front Brake Rotors
• 2 Rear Brake Rotors
• Front Ceramic Brake Pads
• Rear Ceramic Brake Pads

This allows owners to refresh their complete braking system in a single installation.

Rotor Specifications

The kit uses factory-sized replacement rotors.

Rotor Dimensions

Front Rotors

• 12-inch (305mm)

Rear Rotors

• 12.8-inch (325mm)

Maintaining OEM dimensions ensures proper brake balance and compatibility with factory calipers and ABS systems.

Ceramic Brake Pad Benefits

Detroit Axle includes ceramic brake pads instead of lower-cost organic compounds.

Advantages of Ceramic Pads

• Reduced brake dust
• Longer service life
• Quiet braking operation
• Consistent stopping power
• Less rotor wear

For daily-driven SUVs, ceramic pads are generally preferred because they provide a good balance of performance and comfort.

OEM-Style Performance

This kit is designed to restore factory braking performance rather than dramatically alter it.

What Owners Can Expect

• Predictable pedal feel
• Smooth stopping behavior
• Good cold-weather performance
• Daily-driver comfort
• Factory-like brake response

For most TrailBlazer and Envoy owners, restoring original braking performance is exactly the goal.

Durability Testing

One feature Detroit Axle frequently highlights is its testing process.

According to the manufacturer, components undergo:

Quality Testing

• Impact testing
• Wear testing
• Fatigue testing

These evaluations are intended to help ensure durability under normal driving conditions.

Installation

The brake kit is designed as a direct replacement.

Installation Benefits

• No modifications required
• OEM-style fitment
• Compatible with factory calipers
• Works with factory ABS systems

DIY mechanics with basic brake experience can typically complete installation over a weekend.

Daily Driving Performance

This kit is best suited for:

Ideal Drivers

• Daily commuters
• Family SUV owners
• Highway travelers
• Budget-conscious repairs
• High-mileage vehicle maintenance

If you’re building an autocross TrailBlazer—which would certainly raise some questions at tech inspection—you’ll likely want a more aggressive setup.

For everyone else, this package offers practical and reliable performance.

Warranty Coverage

One standout feature is Detroit Axle’s warranty coverage.

Warranty

• 10-Year Warranty

Few budget brake kits offer warranty periods this long, making it one of the strongest selling points of the package.

Pros and Cons

Pros

• Complete front and rear kit

The Detroit Axle Front and Rear Brake Kit delivers exactly what most TrailBlazer, Envoy, Rainier, Ascender, and Bravada owners need: affordable, dependable braking performance.

With ceramic pads, factory-sized rotors, direct bolt-on installation, and an impressive 10-year warranty, this package represents strong value for drivers looking to restore braking confidence without overspending.

If your goal is reliable daily driving rather than track-day heroics, this Detroit Axle kit is a solid choice that keeps your SUV stopping safely for years to come.
