    Hi, I've been looking into why my handbrake pulls up well on the divers side but is almost ineffective on the passenger side? Upon inspection it seem the clearance between the handbrake arm and the wheel hub is inadequate on the passenger side as shown below. This is not the case on the drivers side. any advice here regarding how to adjust this would be appreciated.

    To adjust the rear brakes you normally have the drum and wheel on and just jack the car up, handbrake off and adjust the star adjusters from the rear of the backing plate in a clock wise direction, doing them star adjustments evenly, until you can't turn the wheel, then you back off the star adjusters(anti clockwise) evenly until the wheel can be turned by hand. Is the handbrake lever hitting the center hub? Has the handbrake lever got the correct bent in it ? In your second photo the brake shoe top right looks like is coming out of the wheel cylinder.

    Thanks Wayne, well spotted, ill check if its coming out of the top wheel cylinder when applied. The star adjusters a pretty siezed up so I just needed to see what was going on in there. Yes the problem seems to be that the arm hits the wheel hub and i'm not sure what to adjust to give it more clearance? Do the spreader arms wear and allow the gap to close up over time?

    Wouldn't think the spreader bar would wear enough to cause the issue. Normally the pin that holds the spreader onto the shoe uses a horse shoe shape clip which goes onto the pin. Have seen them come off therefore people replace them with a nut and bolt, which looks like what yours has been done, Make sure that the nut is still on! and that the handbrake lever is against the shoe. You don't want it that tight that it want pivot but firm enough that want come undone. nylon lock nut !

    Back the handbrake cable right off so its slack, adjust the shoes until they just start to drag then stand on the brake pedal a couple of times this will recentre the brake shoes, readjust the shoes if necessary.
    Lastly, adjust the handbrake cable as req'd making sure the brakes release when the handbrake lever is returned.

    As Geoff posted.....don't adjust the handbrake until the brakes have been adjusted without any tension in the h/b cables....a couple of good stomps on the pedal should centre the shoes, then, if necessary, adjust the cables......
    I'd pull the star adjusters and clean 'em up now that you have the drums off.......it's a messy job but worthwhile. Plenty off copper (anti-seize) grease on the s/a posts and they'll be good for ages.
    Cheers,
    Mark

    Thanks Mark, finally got to have a look in there after building up the courage to put the required pressure on the hub nuts, used a length of scaffold tube on the breaker bar, about 2m leverage and off they came!!

    ........and you’ll need to use the same scaff. tube to do ‘em up again !
    Just stand on the tube and use your body weight....from memory they need over 200 ft. lbs of torque.
    Cheers,

    First of all. Loosen the handbrake cables right off. Then adjust the shoes to the perfect position. Then adjust the cables.

    It could be the lever is bent or spreader bar worn or brake shoe slot worn. Compare the parts to the other side or just replace them.
