Coach stops OK, but takes heavy foot pressure. Not sure if this is an air problem or if I need brakes. Anyone know what a brake job costs on a class A diesel?
lrquil,
The short answer to your issue is, it could be a lot of things.
1. Improperly adjusted slack ajusters
2. Leaking oil seals on any one or more of the hub seals
3. Glazed brakes due to over use (too dependent on) the use of the exhaust brake and not using the service brakes on a regular basis
4. As Brett was alluding to, possibly low air pressure.
Now, for the bad part. Partner, without sounding too condescending or derogatory here, you maybe should park that thing and LEARN ABOUT AIR SYSTEMS and air brakes. You state you've had 6 coaches in the last 20 years and ALL BUT ONE has had air brakes and, you DON'T KNOW ABOUT CUT IN AND CUT OUT air pressure? Wow.
Sir, there's a lot going on in front, behind and underneath you when running a diesel coach. What I'm say is not meant for you to become a master diesel mechanic, not even close. I'm just saying due to you owning and operating a diesel coach, (and apparently 4 others) WITH AIR BRAKES, you really should know even some basics.
This will give you some operational knowledge on how your system works, when things might be wrong, or if your air system is building air properly and in the appropriate amount of time so that your brake system works as it's designed and, even things like low air warning, automatic spring brake air pressure, things like that. Again, not trying to belittle you, just saying that, based on your statements, you are unaware of even the basic things diesel coach drivers need to know to be safe. Good luck.
