Concern

Loss of braking effort

Defect, as DVSA words it

On some TRISTOP� actuators the chambers may not have been correctly assembled and the load from power spring and pressure is not fully taken. Under certain circumstances the parking side and the service sides of the actuator could separate and the actuator could lose functionality. Ultimately this could lead to a loss of braking functionality and/or brake failure. Critical applications are vehicles such as city buses or garbage collection vehicles (subject to a high parking brake frequency).

Remedy, as DVSA words it

Identify and replace affected actuators.

What changed since we first read it

Nothing yet. The wording has been the same on every read since 4 September 2026. The file is read again every day; if DVSA rewrites the defect, remedy or concern, the old and new text will appear here with both dates.

The same recall in other registers

No match found in the American, Canadian or European registers by manufacturer reference, because DVSA lists none for this recall. A recall can exist abroad under a different reference; this site only claims a match when the reference agrees.

Reading this against the source

This page is what the DVSA published in its file of vehicle recalls, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /uk-recalls, and how the reading is done is set out in the method.
