RE:

Technical Service Bulletin (TSB)
2024 Model Z – Trailer Brakes
Lippert TSB#45B-001-2023

Dear :
We would like to address some of the questions that have surfaced regarding a potential brake concern
on the Lippert axles used on Model Z. Although this issue has only affected some units, we have made
the decision to replace all brake and hub assemblies on the Model Z units with the following serial
numbers (last 6 of your VIN):
000004 to 000512, 000514, 000516, 000517, 000518, 000521 to 000535, 000539, 000540, 000542,
000543, 000545, 000546, 000547, 000551 to 000555, 000557, and 000558.
If you received this correspondence, your VIN is contained within the list of affected units.
You are our #1 priority and we have been in constant communication with our axle supplier regarding
this issue. Lippert will be issuing a Technical Service Bulletin (TSB) to our dealers on or around Monday,
June 26, 2023 providing dealers with immediate authorization to replace hub and brake assemblies on
the above-mentioned units. Lippert will be working with dealers to facilitate and expedite parts
shipments.
If you have an upcoming delivery and your VIN falls within the scope, please contact Lippert with your
dealer’s name and VIN number and they will work with the dealer to expedite parts. We will all do
everything in our power to complete the TSB prior to your delivery date.
It should go without saying that if you are experiencing diminished braking performance, you should
have the TSB completed before you continue to use your RV. Even though we may be acting in an
overabundance of caution by completely replacing the hub and brake assemblies, we ask that you
treat this with a sense of urgency.
If you are not near an authorized Brinkley dealer, or if you are in immediate need, Lippert may have a
field service technician in your area who could travel to your location to perform the TSB. If you need
help facilitating completion of the TSB or have any questions regarding your brakes, please email the
Lippert Hotline at [email protected].
We have taken the liberty of answering a couple of what we expect to be frequently asked questions:

1. We are supposed to take delivery next week and our VIN falls within the scope, can we still
pick up our RV?
Yes, we believe so. Please contact Lippert with your dealer’s name and unit number and they will
work with the dealer to expedite parts. We will all do everything in our power to complete the
TSB prior to your delivery date.
2. We are planning on taking a trip next week, and our VIN falls within the scope, are we still
going to be able to go?
If you are experiencing diminished braking, you should have your vehicle inspected and the TSB
completed at your earliest convenience. If you are not experiencing diminished braking, you
should monitor braking performance carefully and if you begin to experience diminished braking,
take your vehicle in for service.
3. We are currently on the road using our Brinkley, what should we do?
If you are experiencing diminished braking, you should have your vehicle inspected and the TSB
completed at your earliest convenience. If you are not experiencing diminished braking, you
should monitor braking performance carefully and if you begin to experience diminished braking,
take your vehicle in for service.
4. How long is the process to change the hubs and brakes out?
Between 4 and 5 hours is the estimated time to replace all 4 brakes and hubs.
You will also be receiving a copy of this correspondence via mail to the address that we have on file. We
intend to include a copy of the Lippert TSB with this mailed letter so that you have all of the information
that is available.
We apologize in advance for any inconvenience this may cause. As campers, we understand the
importance of utilizing your unit during the peak of the camping season and will work our hardest to
keep you camping.
If any questions or concerns should arise, please do not hesitate to contact our Customer Care Team at
[email protected] or (574) 501-4280.

Frequently Asked Questions (FAQs)
1. We are supposed to take delivery next week and our VIN falls within the scope, can we still
pickup our RV?
It is highly recommended that the brakes be replaced prior to you taking delivery. We will do everything
we can to help facilitate getting the repairs completed as quickly as possible. We can work directly with
your dealer to coordinate.
2. We are planning on taking a trip next week, are we going to be able to go still?
Lippert believes that the issues are related to inspections that occurred and that the issue should not be
widespread. If an issue were to occur, you would notice diminished braking and possibly your tow
vehicle would throw a warning on your dashboard indicating there is an issue. We highly recommend
that we try to get the brakes and hubs replaced for you prior to your trip if at all possible. We can assist
with your dealer and Lippert to help facilitate.
3. We are currently on the road using our Brinkley, what should we do?
If you aren’t experiencing any diminished braking capabilities, you should continue to monitor the
effectiveness of our brakes. We can work to try and facilitate the replacements for you upon your return
from your trip. If you are experiencing diminished braking, we can work to try and facilitate repairs at or
near your present location.
4. How long is the process to actually change these hubs out?
Between 4 and 5 hours is the estimated time to replace all 4 brakes and hubs.

brakes and hubs on specific Model Z 5th Wheels. The VINs affected include: 000004 to 000512,

000514, 000516, 000517, 000518, 000521 to 000526, 000528 to 000535, 000539, 000540,

HUB AND BRAKE ASSEMBLY REPLACEMENT
ON BRINKLEY MODEL Z 5TH WHEELS
TSB Number: 45B-001-2023
Product: Hub and Brake Assembly
Date: June 23, 2023

Labor Rate: 2.5 hours per axle

Purpose
This document refers to Brinkley Model Z Series 5th Wheels and the requirement to remove and replace the
hub and brake assemblies with new.
NOTE: It is important that ALL NEW parts are ordered using KIT PN 2023040017. Utilize ALL NEW
parts. Do NOT reuse the old parts, even if the old parts do not appear to be compromised.
We suspect that some hub and brake assemblies used on the Curt axles installed on Brinkley’s Model Z 5th
Wheels may have been damaged in the production and/or inspection process at Lippert. As a result, Lippert
has elected to replace all hub and brake assemblies on certain units. This will affect dealer inventory as well
as retail owned vehicles. See the specific affected VIN’s in the table below.
Below you will find work instructions, parts ordering information and details to file a claim for
reimbursement. Within the next couple of days, Lippert representatives may call your dealership to help
facilitate parts ordering. Communication will be provided to retail customers and we ask that you provide
priority scheduling to perform the TSB. Lippert has a field service team who may be able to help you, should
you need it.
Lastly, as part of the investigative process, we ask that you return the hub and brake assemblies back to
Lippert tagged with the last 6 of the VIN.
NOTE: After completing the hub and brake replacement it is important that the customer perform
the burnishing process in order to properly seat the new brake assemblies and achieve optimal brake
performance. See the last page of this document for full burnishing instructions. For convenience,
we have also placed a link to our instructional video here: Proper Way to Burnish your Trailer Brakes
