Where can customers get parts in the field?
MAXX22T parts are available through Hendrickson aftermarket and in most PDC channels. If a specific aftermarket channel needs set up, contact a Hendrickson sales representative and they can assist.
How do you check lining wear?
The lining wear indicator is located on the caliper casting and physically measure pad thickness. It is important to look at both pads, not just the overall wear. Some competitive products have a visual wear indicator which indicates overall wear, however it is not uncommon for one pad to be more worn than the other and this is not evident unless the pad thickness is measured.
Are special tools required for maintenance?
A tool kit is available from Hendrickson but an 8mm offset box end wrench could also be used.
What are the maintenance costs compared to drum brakes?
Maintenance costs can vary depending on factors such as trailer application, typical operation cycles, payload, driver habits and maintenance schedules. Anecdotally, we have heard that driver habits can play a major role in ascertaining potential maintenance costs. As air disc brakes become more popular on trailers in North America, it will be important to properly educate drivers about the differences in braking characteristics and maintenance practices between drum and air disc.
Is the MAXX22T serviceable?
Yes, the guide pins, pistons, boots and pads can all be replaced. Reference L1063 – Air Disc Brake Parts List for part numbers.
Are there any out-of-adjustment concerns in regards to air disc brakes?
While there are currently no inspection criteria requirements for adjustment on air disc brake systems in North America, following a systematic and routine maintenance schedule is important for ensuring maximum performance from the MAXX22T system. For instance, we recommend regular brake pad inspections to ensure even pad wear and routine rotor checks to validate that the rotor is free from cracks or other potential damage.
Can customers get MAXX22T on competitor suspensions?
MAXX22T is available exclusively on Hendrickson’s integrated suspension systems including INTRAAX® integrated axle/beam/brake systems and VANTRAAX® air slider systems.
