Synopsis

Technician reported the B737 MAX main wheel brake assembly had failed and was seized into the main wheel assembly; and parts were found on the ramp.

Narrative

Aircraft X landed at ZZZ and #3 brake assembly was found damaged and parts of the brake were found on the ramp and the brake was seized to tire and wheel assembly when trying to replace the brake. Upon further investigation [Name] and I accomplished a quick search on the 737 MAX aircraft and found that there is a history of damaged and seized brake assemblies on the 737 MAX Fleet. For example [similar problems affecting five other B737 MAX aircraft] were found during a quick history search. Someone needs to look into this matter more deeply and further investigate why the 737 MAX brake assemblies are being found seized and damaged to the point where they are breaking apart and debris found on the ramp.We need a deeper investigation on the brake assemblies that are being installed on the 737 MAX Aircraft as we are finding these brake assemblies breaking apart and/or damaged during aircraft arrival. It could either be a bad batch of brakes; brake failure or a systemic issue with these carbon brakes on the 737 MAX Aircraft. This needs to be investigated as soon as possible to avoid a possible accident.
