# Service bulletin B340414 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10194296 - Published by NHTSA: 2021\-05\-24 - Manufacturer's number: B340414 - Manufacturer's date: 2021\-04\-01 - NHTSA component: SERVICE BRAKES, AIR:DISC; STEERING: STEERING WHEEL/HANDLE BAR ## NHTSA's summary Diagnosis of Compound Brake System Complaints in M Vehicles: 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components \(less than 212 degrees F\) increases the likelihood of cracks to form. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2021/MC-10194296-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2021/MC-10194296-9999.pdf) The document is the manufacturer's.
