Beschreibung
Zusammenfassung:	An automatic adjuster for a vehicle drum brake includes a strut (30) comprising a first end member (31) interconnected with an intermediate member (29) by a screw thread (33, 34) and a second end member (35) slidingly interconnected to the intermediate member (29) and rotatable relative thereto. A sleeve member (40) is mounted for rotation on the intermediate member (29), and a ratchet wheel (42) is provided on the intermediate member (29) for rotation of the intermediate member relative to the first member and sleeve member (40); a leaf spring (50) acts between the second member (35) and sleeve member (40), and has a pawl (55) engagable with the ratchet wheel (42) upon movement apart of the second member (35) and intermediate member (29) to rotate the ratchet wheel (42). A temperature sensitive element (60,95), is provided to prevent relative movement of the second end member and intermediate member at elevated brake temperatures.
