I learned today more about our truck’s air brake system. Learned by receiving a tour of the underside of our truck from a mechanic.
Diane and I woke up this morning at a small truck stop in Florida where we spent last night. I got up early to drive to the Volvo trucks dealer in Orlando where we had an appointment to get some work done. A leaking air bag and two brake hoses were replaced. The hoses were not leaking but there were wear marks on the outside where they contacted the devices that held them in place.
This is the first time we have used this shop and I was very impressed. I carry a creeper in our truck and asked if I could inspect the work before leaving the shop. The mechanic was delighted to join me under the truck with his creeper and give me a tour. I liked the job he did; so much so that we made an appointment to return on Friday to get more work done.
Our truck is six years old and the cooling system hoses have never been changed. It is only a matter of time before they give way so, as a preventative maintenance measure, we will have them all replaced on Friday. The cooling system will also be given a flush and fill. New coolant will replace the long-life coolant that has been in the truck since we bought it.
We left the shop around noon and headed to our Florida house about an hour away. We’ll stay there through Monday and then go back on the road.
Affected trucks include model year 2008-2018 Freightliner Cascadia and Western Star 4700, 4900, 5700 and 6900 trucks. DTNA says after hard brake applications, the brake light pressure switch may not activate the brake lights with the light application of the brake pedal.
