Question Low Air Pressure Brake Buzzer

air pressure is fine 135 lbs. but alarm buzzers on rear and front brakes continue to alarm. I have changed both low pressure indicators on foot brake but didn't stop the noise or turn off the lights. My RV is a National Tradewinds class A. PLEASE any ideals or does anyone have an electrical diagram of the air brake system on the Tradewinds ? THANKS

It seems like you changed the 2 brake light switchs. They are on the foot pedal valve.

Can't help with the low air switch location but if you remove it the air system will drain to empty. Don't be under it.
