Demers Ambulances is recalling 31 2019-2020 Type I (MXP150E) and Type I (MXP170E) ambulances under recall 20V323 because the rear brake caliper flexible line can contact a suspension component and wear through. A worn line can leak brake fluid and reduce or eliminate rear braking, increasing crash risk; the dealer repair will be free once available.

What's wrong?
The rear brake caliper flexible line on the 2019-2020 Demers Ambulances Type I (MXP150E) and Type I (MXP170E) ambulances carries brake fluid to the rear caliper. The caliper squeezes the brake pads against the rotor when the pedal is pressed, and that pressure helps slow the rear wheels. These ambulances were built on Ram 4500 and 5500 chassis with a LiquidSpring C.L.A.S.S. rear suspension system.
On affected suspension systems, the rear brake line was routed close enough to touch a suspension component. During normal suspension movement, that contact wears the outside of the flexible line. If the line wears through, brake fluid pressure at the rear brakes drops and the ambulance can lose rear braking.
There is no warning sign before failure. An operator should treat any brake fluid leak, brake warning light, or change in pedal feel as a service issue, but the recall filing does not identify a specific advance symptom.
Who's affected?
The same rear brake caliper flexible line issue appears across the Type I (MXP150E) and Type I (MXP170E) ambulance variants.

What's the safety risk?
A worn rear brake caliper flexible line can leak brake fluid and reduce or eliminate rear braking, increasing crash risk. There is no listed warning sign before the leak. Drive cautiously, leave extra stopping distance, and schedule service soon if your VIN is included. Repair will be free at any franchised Demers Ambulances dealer once available.
What should I do?
- Check your VIN to confirm your 2019-2020 Demers Ambulances Type I (MXP150E) or Type I (MXP170E) ambulance is included in this recall.
- Watch for the Braun owner notice, or call Demers Ambulances customer service at 1-800-363-7591 to confirm the repair path.
- Ask a franchised Demers Ambulances dealer about the free rear brake flexible-line and hardware repair that prevents line wear and rear brake loss.
- Bring the recall notice if you have it. If not, reference recall number 20V323 when you call.
- Drive with extra following distance until the repair is complete, and report any brake-fluid leak or rear-brake loss before the ambulance is used again.
What happens at the repair
At the dealer, a Demers Ambulances technician replaces the rear brake caliper flexible lines and related hardware. The work is meant to correct brake hose routing that lets the line contact a suspension component and wear. Parts and labor are covered by the recall. The filing says the recall began July 21, 2020, but this page does not list a current remedy status, so confirm availability with the dealer before arranging service.

Frequently asked questions
What is recall 20V323?
Recall 20V323 covers 31 2019-2020 Demers Ambulances Type I (MXP150E) and Type I (MXP170E) ambulances built on Ram 4500 and 5500 chassis with C.L.A.S.S. rear suspension. The rear brake caliper flexible line can contact a suspension part, wear through, and reduce rear braking.
What should I do if my 2019-2020 Demers Ambulances Type I (MXP150E) or Type I (MXP170E) is on this recall?
Check your VIN to confirm your specific ambulance is included in recall 20V323. If it is, contact a Demers Ambulances dealer to schedule replacement of the rear brake caliper flexible lines and hardware. Reference recall number 20V323 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. For recall 20V323, dealers replace the rear brake caliper flexible lines and hardware free of charge.
What is the safety risk?
The safety risk is partial or complete loss of rear brakes. A worn rear brake caliper flexible line can leak brake fluid, which reduces braking ability and increases crash risk. Until the repair is complete, ask the dealer how to handle service scheduling and vehicle movement.
What if I bought the Demers Ambulances Type I used?
The free recall repair still applies. Federal recall law follows the vehicle, not the first owner. Check your VIN to confirm whether your specific 2019-2020 Demers Ambulances Type I ambulance is included, then give recall number 20V323 to the dealer service desk.
