What's wrong?
The brake caliper is the part of the air disc brake system that holds the brake pads and clamps them against the rotor when you press the pedal. On the 2018-2019 Newmar Ventana Le, Ventana, Essex, London Aire, and Mountain Aire motorhomes, the caliper depends on mounting bolts to hold it tightly to the brake anchor plate. That clamping force keeps the caliper aligned so the pads press evenly.
In this recall, those brake caliper mounting bolts were not tightened to the correct torque. When the bolts are under-tightened, they do not hold the caliper and anchor plate together with enough force. The caliper can move out of position under braking load, which reduces brake effectiveness and raises the risk of a crash or property damage.
There is no warning sign before failure. A driver should not count on a dashboard light, noise, or pedal change to appear before the brake caliper mounting problem affects braking.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
Loose brake caliper mounting bolts can reduce braking effectiveness. That gives the vehicle less stopping force when you need it and increases the risk of a crash. If your VIN is included, schedule the inspection and bolt tightening soon, and avoid extra trips until the repair is complete. Repair is free at any franchised Newmar dealer.
What should I do?
- Check your VIN to confirm your 2018-2019 Newmar Ventana Le, Ventana, Essex, London Aire, or Mountain Aire is included in this recall.
- Contact a franchised Newmar dealer to schedule the free inspection and tightening for loose brake caliper mounting bolts.
- Bring the recall notice if Newmar mailed one. If not, reference recall number 18V859 when you call.
- Ask Newmar customer service at 1-800-731-8300 about scheduling questions or the Newmar recall number 18V-703.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking.
What happens at the repair
At the dealer, a Newmar technician inspects the brake caliper mounting bolts and tightens them to the proper specification. The inspection and any needed tightening are free under the recall, with parts and labor covered. Newmar has a general reimbursement plan on file for owners who already paid out of pocket for this same brake caliper bolt repair before the recall work was completed. Bring documentation for the prior repair and ask the service desk how Newmar handles the reimbursement claim.
