The LiftMaster 10-15033M brake bracket is a structural mounting component used in the brake area of select GSD commercial door operators. Its job is not to create braking force by itself; instead, it holds the brake assembly in the correct position so the brake components can engage and release properly. A bent, cracked, loose, or missing bracket can cause poor brake alignment, inconsistent stopping, dragging, vibration, or damage to related brake hardware. This part is most useful during a brake service where the technician is rebuilding or correcting the mechanical brake mount, not during a basic remote or wall station issue. Commercial door brake repairs should be handled carefully because poor brake operation can create unsafe door movement.
This replacement part supports the correct operation of the compatible LiftMaster commercial operator assembly. It should be selected by exact part number, operator model, and parts breakdown. For commercial door equipment, related wear items and electrical conditions should be checked before replacing a single part so the new component is not damaged by an unresolved operator problem.
This item is commonly associated with the following LiftMaster operator families, product groups, or applications. Use the full operator model tag and parts diagram to confirm the exact fit before service.

The following numbers and search variations are commonly associated with this item. Related numbers may be aliases, kit formats, older numbers, or catalog variations and should be checked against the operator parts diagram.
For commercial LiftMaster parts, do not order by appearance alone. Match the original part number, operator model, logic generation, voltage where applicable, and the replacement parts diagram. Similar-looking covers, shafts, brackets, transformers, sensors, cables, and surge components may not interchange between operator families or production generations.
Commercial door operators contain moving mechanical parts and, on many models, high-voltage electrical circuits. Disconnect power before service and follow the operator manual. Electrical transformer, MOV, sensor, and control-circuit work should be performed by a qualified commercial door technician. Do not bypass safety devices or operate a commercial door system with unsafe movement, missing covers, damaged wiring, or unresolved mechanical binding.
It supports and positions the brake assembly on select LiftMaster GSD commercial door operators.
Yes. K10-15033M is commonly used as the kit or catalog format for the LiftMaster 10-15033M brake bracket.
The number 10-10446 is commonly listed as a related number for this brake bracket family.
It may help if the bracket is bent or damaged, but the brake solenoid, friction parts, wiring, and control circuit should also be checked.
No. It is primarily associated with select GSD operators and should be matched to the operator parts diagram.
