# Service campaign MC340224

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.

- [MC320224](/bulletins/11013432.md), 2025-02-03, Service campaign: SERVICE BRAKES. The Blow\-By clearance tolerance at the handbrake lever fitting may be below than what is stated by the manufacturer, which can lead to slight braking pressure in the front brakes under certain settings \(e.g. warm outside temp to warm breaks, etc…\) with a slow release of pressure over time. Several conditions must be achieved for this to occur: 1.The FCW \(Front Collision Warning\) rider assistant system must be activated. 2.The FCW must trigger a warning based on the traffic condition. Moderate pressure must build up in the brake system during this warning trigger. 3.The handbrake lever fitting’s blow by clearance must be below the tolerance level specified by the manufacturer. In some instances, the brake pressure built up by the FCW will not release immediately because the sealing lip in the piston can become blocked by the insufficient blow by clearance and will slowly release the pressure over time. In the cases above, it is always the result of an incorrectly adjusted handbrake lever fitting as the FCW assistance system works correctly and reliably. Only in isolated cases the manufacturer had delivered handbrake lever fittings in which the blow by clearance is set too low. NOTE: The Standard setting of the handbrake lever fitting piston blow by clearance MUST NOT be adjusted, not even to adjust free travel or for assembly of aftermarket accessory levers\!\!\!\!\! The seal on the locking screw is to prevent manipulation and MUST NOT BE BROKEN. Examples of untampered and tampers fittings are below with an example of the location.
