What's wrong?
On 2019-2021 Trail King Tkahg, Tkhg, Tkmg, Tkmb, Tkhdg, Tkamg, and Tklpsd trailers, the disc brake chamber extension tube is part of the front axle brake assembly. It helps connect the air brake chamber to the disc brake caliper mechanism, which applies and releases braking force at the wheel.
On the recalled trailers, sealant was left off during axle assembly. Without that sealant, water can get into the extension tube area. Water inside the front axle brake hardware can lead to corrosion, and in freezing conditions it can freeze around the caliper mechanism. Either problem can keep the front axle brakes from moving as designed.
Owners can notice the front axle brakes sticking or failing to release after braking. That is the warning sign to take seriously, because the brake hardware is no longer returning to its normal released position.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Caliper corrosion or freezing can reduce front braking effectiveness and increase the risk of a crash. A front axle brake that sticks or fails to release is a warning sign. If that happens, stop the trip and call Trail King or the dealer before moving the trailer again. Repair is free at any franchised Trail King dealer.
What should I do?
- Check your VIN to confirm your 2019-2021 Trail King Tkahg, Tkhg, Tkmg, Tkmb, Tkhdg, Tkamg, or Tklpsd trailer is included in this recall.
- Contact a franchised Trail King dealer to schedule the free front axle brake inspection and extension tube sealing that addresses water intrusion into the caliper mechanism.
- Ask the dealer whether the caliper needs free replacement if corrosion or freezing is found.
- Bring the recall notice if Trail King mailed one. If not, reference recall number 21V066 and Trail King recall TK202101 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking.
What happens at the repair
At the dealer, a Trail King technician inspects the front axle brake system and seals the disc brake extension tube where sealant is needed. If water has entered the caliper mechanism and caused corrosion or freezing, the technician replaces the affected caliper. Parts and labor are covered under the recall. Trail King has a general reimbursement plan on file for owners who already paid for this repair. Keep repair paperwork and contact Trail King customer service about documented repair costs.
