What's wrong?
The brake caliper is the part that holds the brake pads at each wheel and squeezes them against the rotor when you press the pedal. On these 2017-2019 Newmar Ventana Le, Ventana, London Aire, Essex, and Mountain Aire motorhomes, the issue is not the pad itself. It is the mounting bolts that hold the caliper firmly to the brake anchor plate.
Those bolts were not tightened enough to provide the required clamping force between the caliper and the anchor plate. If the bolts loosen, the caliper loses the firm position it needs during braking. That can reduce brake effectiveness, which increases the risk of a crash or property damage.
There is no warning sign before failure. An owner can feel normal braking before the loose hardware affects how the brake caliper holds and applies the pads.
