What You're Actually Buying
This is a 430mm rotor for the ConMet ADB22X air disc brake system, 10-bolt mount. ConMet's own number on this kit is 10080820, and CV60479K is how it shows up in a lot of catalog systems and on invoices — same part, different reference point depending who's writing it up.
ADB22X is Meritor's air disc caliper design, and ConMet builds the rotor to match. You'll find this rotor on newer Class 8 trucks and some medium-duty applications running air disc up front — Freightliner, Kenworth, Peterbilt, and others depending on how the truck was spec'd off the assembly line.
430mm is the rotor diameter — don't guess on this, measure the old one or check your build sheet. There's more than one rotor size running around on ADB22X systems and they are not interchangeable.
How the Cross Numbers Line Up
Meritor lists this rotor under M44D802081 and M44D76618 — those are Meritor's own part numbers for the same physical rotor, since Meritor designed the ADB22X caliper and ConMet builds rotors to spec for it. BR950008-04 is an aftermarket number floating around for the same fitment.
Bolt pattern is the big thing to verify — this is a 10-bolt hub mount, and rotor diameter has to match your caliper mount exactly. Air disc rotors aren't like old S-cam drum setups where you had some wiggle room on interchange; these are matched to a specific caliper bracket and hub assembly.
Surest way to confirm: pull the number off your old rotor or run the VIN. If the old rotor's stamped with any of the numbers in the table, you're good. If it's worn past reading, check with your caliper part number instead — that'll tell you which rotor size and bolt pattern you're actually running.
Ordering From PartStop
We're in Tacoma and this one's a common enough number that we usually have it on the shelf — same-day pickup if you're local, otherwise it ships out same day for most orders placed before cutoff. We move a lot of ADB22X stuff so we're not guessing on this fitment, but we still tell you to confirm the number.
Comes with the standard 6+ month warranty. If it turns out to be the wrong rotor for your setup, we'd rather swap it before it goes on the truck than deal with a comeback after — call the counter if anything looks off when it arrives.
CV60479K Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to CV60479K. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.
| Brand / Line | Cross-Reference Numbers |
|---|---|
| ConMet | 10080820 |
| Meritor | M44D802081, M44D76618 |
| Aftermarket | BR950008-04 |
Frequently asked questions
Does CV60479K fit my Freightliner Cascadia with air disc brakes?
Probably, if it's running the ADB22X caliper and 430mm rotor — but Cascadias came through with different brake specs over the years. Check the number stamped on your old rotor or give us the VIN and we'll match it before you order.
Is this the same as the Meritor M44D802081 rotor?
Yes — M44D802081 is Meritor's number for this same ADB22X rotor. ConMet builds it to Meritor's caliper spec, so the physical part crosses over. Confirm the diameter and bolt count still match what's on the truck now.
Can I mix this rotor with a different brand caliper?
Only if the caliper's actually an ADB22X unit — the rotor's matched to that caliper design specifically, not just any air disc caliper. If you're not sure what caliper's on there, check the casting markings or pull the number and call us before ordering.
