I have noticed the past few months that as the coach sits for a few days the brake pressure is 0 when I start the bus. It comes right up to 118-123psi 2-3 minutes after starting and maintains that pressure while traveling.
Is this an issue or just normal for a coach that has a few years on it? I remember reading "horror stories" about chasing down an air leak. Any thought or advice would be greatly appreciated.
Thanks
Jamie
