Thank you Both I will check on Both of those today

Hi Jim, Thanks for the reply. I noticed it after buying it. So with me it's been the whole time. it does engage but takes about 5 or 10 seconds. Also I just replace an abs solenoid. it was pouring out Air and couldn't build up enough air pressure to release the parking brake. The parts guy stated that I had blow back coming from the out side of the solenoid.

Good morning, I'm new to this site and to dump trucks. I have a 2004 Mack Granite and when I engage the parking brake it doesn't engage right away. Any ideas on where to start. I have checked for air leaks at the brakes and didn't find any. Any advise would be much appreciated
