From your post, I assume you mean that the tow vehicle brakes are doing the squealing.
Do you park outside?
there are several reasons for a squeal.
Most common is a worn pad with a built in wear indicator which is designed to squeal when the pad gets thin enough.
Another common cause is when the vehicle has been parked outside or driven after a rain. Rust or moisture can can cause the squeal but it usually goes away after applying the brakes a few times.
Sticky slides on the caliper can cause a pad to jamb or get crooked causing noise when the brakes are applied. This is often the inside pad gets stuck and wears away quickly.
Some cheap pads come without anti-rattle springs or backing plates which can make them noisy
Some metallic compounds are just prone to squeal.
Raybestos "Quiet Stop" pads are ceramic based, quiet and make virtually no noticeable dust on your wheels.
These were all generalities and a true diagnosis would require checking the vehicle in person.
The likely reason that the squeal does not occur when towing is that you are applying the brakes harder and the pads are gripping past the squeal point.
