2016 CRV brake and rotor

Check prices on Rockauto, Napa and some online canadian autoparts retailers.
For rotors, get coated ones since we have salted roads (don't getbthe slotted ones, those will chew away your lads really quickly and are meant for racing). For pads, get full ceramic ones. Remember lube the sliding pins with silicone paste (don't use permatex, it swells the rubber) and bleed the brakes while you're at it

It's an easy job, you can do it yourself. Plenty of videos on youtube on how to do it for your model.

Good luck

You only change the rotor if it's below the minimum specs set by your manufacturer, check yoournowner's manual. Aldo, if it is warped, change them since it eats away brake pads unevenly and causes vibrations in the steering wheel.

Always change brake components in pairs.

At that mileage, change the rotor. The labour to chip off the rust and machine the old rotor will almost offset the cost of the new rotor. Plus, a new rotor will be better at dissipating heat - which is better for your pads, bearings, and nearby suspension components. If you have tools, this is about a $200 DIY job. A dealership will likely charge around $800 to do both front brakes. An independent garage slightly less.

A wild-ass guess since I don't have any Honda experience but based on experience on a number of cars over the years.

If you've been happy with the brakes, stick with OEM.
