Vehicles that sit develop their own problems
Plenty of vehicles around here are seasonal. A truck used heavily for part of the year and parked for the rest, a second pickup, a vehicle that comes out when the work does.
Brakes do not like sitting. Rotors develop surface rust, which is harmless and clears in a few stops. What is not harmless is what happens over longer periods: caliper slide pins seize in place, parking brake cables bind, and moisture that has been sitting in the brake fluid gets to work on the inside of the system.
The vehicle then comes out of storage and the first hard stop is the test. Pulling to one side, a wheel that runs hot, a parking brake that will not release, or a soft pedal are all symptoms of standing rather than of use.
Bring a seasonal vehicle in before you need it rather than after the first week of work, and say how long it has been parked.
Dust and brake wear
A vehicle working gravel and field roads is throwing abrasive material into the brakes continuously, which shortens pad life compared with the same vehicle on pavement.
The schedule in the manual assumes average conditions. Inspection intervals here should follow the conditions instead, and a brake check while the vehicle is in for an oil change costs nothing.
What the inspection covers
Pads, rotors, calipers, hardware, hoses and fluid, as a system rather than as the noisy part. A seized caliper slide is a common finding and shows up as uneven pad wear across an axle.
Brake fluid absorbs moisture over time, whatever the mileage, which lowers its boiling point and corrodes components from inside. It can be checked rather than assumed.
Towing changes the sums
A pickup towing a trailer is asking a great deal more of the same brakes, and heat is what wears them. If your vehicle tows, the inspection interval shortens accordingly.
