My 2015 Chevy Traverse has about 75,000 miles on it with the OEM brakes. It was built in December 2014. It sees a lot of city and some highway miles. So far the amount of pad material looks Ok, but I wanted to see if there was any knowledge of a time-based replacement interval. Any constructive feedback is appreciated.
My driving style can be described as calm, yet controlled aggression.
Let me give you my experience on this question in general because in my world, the question( and the answer) remains the same no matter what the application.
Every single client who has ever hired me to do a maintenance assessment asks that same question- give me a PM schedule for "X". They all want it to be perfect, reduce downtime, save money on MRO and increase asset lifecycle and address overall total cost of ownership. ( everything of course)
Then they want a "number" based on a "meter" ( be it hour meter, odometer, cycle count, calendar or whatever) to plug in a CMMS to spit out.
So, if you define "needs replacement" specifically as when the "thing" is no longer capable of performing to design requirements.....( which is really the only measureable definition of "needs' replacement as opposed to a "good idea")
Any "meter based PM" has a risk of replacing a serviceable part with another serviceable part. ( more of a financial risk than anything else)- on the other side, it carries an equal risk of possibly incurring a degree of damage if the meter is too long. ( risk of downtime or higher cost to operate and possible future reduction in operating capacity)
Inspection PM or PdM increases accuracy of a "condition based assessment" decision to act but carries a cost and investment in time and money and often the true results are "intangible".
Then there is the business based decision to "replace certain parts at a given schedule or frequency because the risk of possible failure is unacceptable"- this is often done and could be said for changing all belts/hoses at "whatever' just to avoid the potential for a bigger event later.
I have never seen a viable one-size-fits-all solution to this question.
All of those strategies are legitimate and work- all of them carry a degree of risk and cost- all of them require a decision based on specific circumstances.
I would proffer that you decide what's most important to you in the way you operate your vehicle and what level of risk you deem acceptable and implement it.
