2017 GMC Acadia: Brake Pad & Rotor Specifications

As an ASE-certified master technician, I've seen it all when it comes to brake wear. For the second-generation GMC Acadia, which debuted in 2017, GM built a solid braking system. However, like any wearable component, it requires regular inspection and service. This guide provides the critical specs, part numbers, and technical advice you need to perform a professional-grade brake job on your 2017 Acadia.

Note: The 2017 Acadia was a complete redesign. There is also a "Limited" model which is a carryover of the previous generation. This guide is for the redesigned, smaller 2017 Acadia. Always verify part numbers with your VIN at the dealership parts counter.

Quick Reference: 2017 Acadia Brake Specs

How to Choose Brake Pads

Selecting the right brake pad compound is a balance of performance, noise, and durability.

• Ceramic: For the vast majority of Acadia owners, a quality ceramic pad is the best choice. They offer excellent stopping power for daily driving, are exceptionally quiet, and produce very little brake dust, keeping your wheels cleaner. Brands like Akebono and Bosch QuietCast are top-tier ceramic options.
• Semi-Metallic: If you frequently tow with your Acadia or live in a hilly area, a semi-metallic pad might be a better fit. They provide a stronger "bite" and dissipate heat more effectively under heavy load. The trade-offs are typically more brake dust and a higher potential for noise compared to ceramics.
• Heavy Duty / Towing: Purpose-built towing pads (like those from Power Stop's Z36 line) are an evolution of semi-metallic formulas. They are designed for maximum heat resistance to prevent brake fade during long descents with a trailer. They are the most aggressive option and are overkill for a vehicle that isn't used for towing.

Typical Service Life

For a 2017 GMC Acadia, you can expect the factory brake pads to last between 30,000 and 70,000 miles. This wide range is heavily dependent on your driving habits.

• City Driving: Constant stop-and-go traffic will wear pads out on the lower end of that spectrum.
• Highway Driving: If your commute is primarily on the freeway, you could easily see over 60,000 miles.
• Towing: Pulling a trailer significantly increases the workload on your brakes and will shorten their lifespan.

The concept of a "pad-slap" (installing new pads on old, un-serviced rotors) is not recommended. For the safest and most effective braking, rotors should be machined (if they are thick enough) or replaced with every pad change. This ensures the new pads have a perfectly flat, true surface to bed into, eliminating vibrations and maximizing performance.

Common Brake Issues for This Generation

The 2017+ Acadia platform has a generally reliable brake system. However, there are a few things to watch out for:

• Electronic Parking Brake (EPB): The rear calipers are equipped with an EPB. You cannot simply press the rear piston back into the caliper. Doing so will damage the EPB motor. The system must be put into "Service Mode" using a capable bi-directional OBD2 scan tool. This retracts the motor electronically, allowing the piston to be compressed. If you are a DIYer, this is the most critical step of a rear brake job.
• Noises: Some owners report squealing or light grinding sounds. This can be caused by aftermarket pad quality, improper lubrication of contact points and slide pins, or failure to properly bed-in the new pads and rotors. Always use a high-temperature synthetic brake grease on all metal-to-metal contact points (except the pad/rotor friction surfaces) and follow the manufacturer's bed-in procedure.

Brake Job Cost Estimate (per axle)

Costs can vary significantly based on your location, the shop's labor rates, and the parts you choose.

• DIY Cost: Expect to pay between $150 to $400 for a set of quality pads and rotors for one axle.
• Independent Shop Cost: A professional replacement of pads and rotors on a single axle will typically cost between $450 and $750. If a shop suggests only machining the rotors, the cost might be slightly lower, falling in the $350-$550 range.
• Dealership Cost: Dealerships using OEM parts will generally be the most expensive option, often ranging from $600 to $900+ per axle.

Whether you're tackling the job yourself or taking it to a professional, using the correct specifications is key to a safe and successful brake service.
