I donât feel guilty in the slightest, Iâve been vanning for over 30 years, we get our caravan serviced every year and the brakes are always stripped for inspection. Despite the service, there are always creaks and groans during towing but they are what they are - if you are concerned get it checked, otherwise turn the radio up and enjoy your holidays.
We have no way of knowing what the source of the OP's noise is, so I cannot believe that a potential issue with a primary safety system on a vehicle is being treated with such contempt by some contributors.
We know from post both here and in other threads that both the manufacturers and the service shops have missed critical issues becasue there is no statutory testing regime for trailers brakes and other road going equipment, (In other words a statutory MOT). We rely on the professionalism of the services we have done , and whilst in general they do try to do a good job, sometimes (as described in other posts) there is good reason to be suspicious about some.
Any suspicion of a problem with a primary safety system such as brakes should never be dismissed or ignored or masked by turning the radio up. It should be a matter immediate concern to arrange to get the system professionally checked out as soon as possible. To suggest other wise is entirely irresponsible.
See #8 and post #18. OP in #8 states that recently serviced by dealer etc however they only mention the age of the caravan in #18. None of us have anything to feel guilty about regarding any incident that may happen as prior to #18 we gave them good advice on what is normally a common problem with ALKO brake drums. Until it is properly investigated, there is nothing more that can be added at this point.
I will decide based upon my own understanding of a situation or system if , what and when I add a comment. But based on your own assessment and conclusion "Until it is properly investigated, there is nothing more that can be added at this point." Its strange that you have not heeded your own advice. by adding #30
