2017 Subaru Crosstrek Brake Specs & Reference Guide

As an ASE-certified master technician, I’ve serviced countless Subarus over the years. The 2017 Subaru Crosstrek is a phenomenal crossover, blending car-like handling with rugged capability. Because it’s often used for commuting, weekend adventures, and traversing mountain passes, the braking system works hard. Whether you are performing a DIY brake job or just want to be an informed customer before heading to the shop, having the exact brake pad and rotor specifications is critical for a safe, reliable repair.

Below is your comprehensive guide to the 2017 Subaru Crosstrek braking system, covering torque specs, OEM and aftermarket part numbers, and rotor discard limits.

Quick reference

Here are the essential brake specifications for the 2017 Subaru Crosstrek. Note: Torque specs and minimum thicknesses can vary slightly by trim; always verify with a service manual or dealer.

How to choose pads

Selecting the right brake pad friction material is the most important decision you'll make during a brake job. The 2017 Subaru Crosstrek responds well to a few different types of compounds, depending on how you use the vehicle:

Ceramic Pads: This is the factory-style replacement and the best overall choice for 95% of Crosstrek owners. Ceramic pads, like the Akebono ProACT series, offer exceptionally low dust, quiet operation, and a smooth pedal feel. They are perfect for daily driving and light trail use.

Semi-Metallic Pads: If you live in a mountainous region where long descents heat up the brakes, or if you regularly tow a small trailer, semi-metallic pads are worth considering. They offer superior "bite" and fade resistance compared to ceramic pads. The trade-off? They produce noticeable black brake dust and can occasionally squeal, particularly when cold.

Heavy Duty / Performance Pads: Brands like Power Stop offer upgraded pad and drilled/slotted rotor kits (e.g., Z23 Evolution Sport). While a standard Crosstrek rarely needs a heavy-duty track-style pad, these kits offer improved thermal management if you have upgraded your vehicle with heavy oversized all-terrain tires and roof tents that add significant weight.

Typical service life

On the 2017 Subaru Crosstrek, brake longevity heavily depends on driving habits and environment.

• Front Brakes: Most drivers will see between 40,000 and 60,000 miles out of the front brake pads.
• Rear Brakes: Because of Subaru's Electronic Brakeforce Distribution (EBD), the rear brakes actually do a fair amount of work to keep the chassis level during stops. Expect rear pads to last 50,000 to 70,000 miles. It is not uncommon for rear pads to wear out at the same time, or slightly before, the fronts depending on your cargo loads.
• Rotors: Factory rotors are generally robust enough to last through two sets of brake pads. If they are above the minimum machine thickness (22mm front / 8.5mm rear), they can be resurfaced. However, many technicians recommend simply replacing the rotors with the pads ("pad-slap" interval of replacing rotors every other pad change, or replacing both every time for maximum smoothness).

Common brake issues for this generation

The first-generation Crosstrek (2013-2017) has a highly reliable braking system, but there are a few quirks you should be aware of:

Seized Slide Pins: Subaru calipers use slide pins that require regular lubrication with a high-quality silicone-based brake grease. If the rubber boots tear, or if the pins dry out in rust-belt states, the caliper will bind. This leads to uneven pad wear (one pad worn to the metal, the other looking brand new) and a spongy brake pedal. Rotor Warpage (Thickness Variation): A pulsating steering wheel when braking at highway speeds is a classic sign of disc thickness variation, commonly called "warped rotors." This is often caused by lug nuts being over-torqued by impact wrenches at tire shops. Always torque your lug nuts to 89 ft-lbs using a calibrated torque wrench to prevent this. Rusty Rear Rotors: Because the rear rotors do slightly less work than the front in light braking scenarios, they are prone to rust build-up on the braking surface in wet or snowy climates.

Brake job cost estimate

If you are tackling this job in your own garage, a full set of quality aftermarket ceramic brake pads and coated rotors for both the front and rear will run you approximately $250 to $350 in parts.

If you take your 2017 Crosstrek to a professional shop or dealership, labor and markup will increase the price.

• Front Pad and Rotor Replacement: $350 – $500
• Rear Pad and Rotor Replacement: $350 – $500
• Full Four-Wheel Brake Job: $700 – $1,000

Always ask the shop what brand of parts they are using. Paying a slight premium for coated rotors (which prevent ugly rust accumulation on the rotor hat) and premium ceramic pads is always money well spent.
