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
