Grand vitara rear brakes over adjusting automatically.

[crazynic]

Hi guys,

I've found an issue with the rear brakes on my grand vitara (99)..

The rear brakes "self" adjust until the brakes actually start to drag noticeably.

At first i thought it was because i have a 50mm lift in the rear and there may not have been enough slack left in the hand brake cable but i un-bolted the cable from its mounts to relieve any tension and it has not helped.

Then when i had the drums off to back off the brakes i removed the little lever plate that moves the star wheel for self adjustment thinking this would help stop the issue.........but it still tightens up the rear brakes.

I back them off so the adjustment is correct then slowly but surely i notice the hand brake lever travel diminish until the rear brakes are dragging!

The rear shoes are in good condition and im running out of ideas!

Could it be a load proportioning valve problem?

I have never meet a set of rear drums so intent on self adjusting (even with the self adjuster plate removed!) the normally never adjust themselves.
