Air brake questions?

Do you have hydraulic disk brakes (like older Safari coaches) or air drum.

Maintenance is COMPLETELY different.

Yes , I can only go on my prior experience as a commercial driver, not mechanic, that would say the average RV’er would never need to change the brakes out. 200,000 miles is I believe a realistic number. This is of course for a heavy duty air brake system.
If you ride the brakes , have a lot of mountain driving without proper Jake/ Exhaust Brake use, or any of a large list you may not get there. A competent inspection should quickly determine pad thickness and / or if a adjustment is needed. If in fact your pedal pressure needed is increasing it needs something. Get it looked at . I’ve never paid to have the brakes replaced , but like all things DP I can believe it “ain’t” . Cheap to have done.

I’m the original owner of my 2004 Country Coach and I have 84,000 plus miles. My Pac Brake is always on and I have always had a supplemental brake system on the three toads I have used. Most of my miles have been in the mountain west States. My mechanic at the last service said I had about 85% brake left.

Do you use the exhaust brake more then 90% of the time?

Using it will help to extend brake pad life.

We are at 71K on our 2004 Safari and its beginning to require more pressure on the pedal to stop. That's probably the answer to my question ay!

Coach Cleats, you are right in acknowledging huge differences in the mileage expected but, at 71K, your brake shoes "could" have significant life left. However, other parts in the system age and as self adjusting air brakes age and wear they will require maintenance. These brakes will only self-adjust within a certain tolerance; when the air brakes go beyond this tolerance they must be serviced.

If you are not able to check them yourself, have it looked at by a professional-you may not need anything more than routine inspection and maintenace. If it has been sometime since your air brake system has been checked and serviced, it's time to have it looked at.

Ours at 62K miles are at 75% life or more I estimate.
