    Corsa B hand brake adjusment

    Afternoon all

    Been outside for the past hour, checking out a friends corsas handbrake, drums off both sides, shoes were looking well, about 3-4mm of life in them, minimum was .5mm but was nowhere near that

    Adjusted the drivers side, solid as a rock, however I assumed the same nut I was adjusting was the passenger side. But it wasn't.

    Checked out the adjusters, they had seized, managed to unseize them and put a dab of grease on the adjuster, handbrake was a little better, so it was a struggle to turn the wheel but it still isn't gunna pass an MOT.

    Any ideas at all? could it be that the cable is goosed?

    have you adjusted the nut on the hand brake leaver or on the drums them selfs? you need to adjust the drums till it bits nice then when its correct on both sides, tighten the nut on the leaver

    They're self adjusters on the drums themselves matey

    I checked the handbrake lever and there wasn't any adjuster like the astra mk4 one. Rather strange

    They 'are' self adjusters but never work so you need adjust them through one of the wheel bolt holes till they just start to bind then back them slightly.

    The adjuster is ratcheted so its quite easy to see what way to turn it.

    Once the rear drums are adjusted you can then take up any slack (Reducing the number of clicks) on the threaded bit of the cable under the handbrake cover:

    Yes,

    You adjust the 'brakes' at the drum through the wheel bolt hole 'Then' take up the handbrake slack.

    That should still be under the gaiter

    Right, replaced the cable, as it was goosed, but you can still turn the wheel on the passenger side more than the drivers side, its a lot better than it was. Drivers side is spot on.

    I still don't get how you adjust the mech through the wheel bolt hole though? and there is definitely NO adjuster nut on the handbrake arm itself.

    did one of these last week on the wifes corsa b, once you have replaced the cables, manually adjust the rear shoes and then pop the drums on so they slightly rub when turning by hand. then put the handbrake on 2 clicks and turn the handbrake adjuster bar on the back beam until the handbrake locks the wheels on 2 clicks. i think it was a 6mm and 11mm/12mm spanner, one to hold the cable nut and the other to turn the adjuster

    How do you go about manually adjusting the rear shoes though? is it a case of moving the bottom ends of the shoes as far away from each other as possible so its just catching the drums?

    Funny thing is, that one nut adjuster only seems to do the drivers side and not the passenger side.

    the adjuster should pull equally on both drums through the adjuster bar, mate. ensure the adjuster bar componants are free and not seized, whack a good dob of grease in the bar and to adjust the rear brakes you need to remove the drums and click the adjuster arm on the top adjuster bar wheel, clockwise two clicks then put the drums on, pump the brake pedal twice then turn the drums by hand and keep doing this procedure until you get a slight grab on the drum, job done.
