Handbrake failure

    This is what mine is! I thought it was ok until I opened the slidey door and the van starting rolling backwards!

    I have laid beneath the van in an attempt at looking like a mechanic and have decided that there are two cables running to the rear wheels that do the handbrake. I feel as though they could be adjusted but also feel it could go wrong if you (me) weren’t sure what you were doing.

    Mick, the old farm mechanic, said adjust the brakes with a screwdriver. I actually vaguely remember doing that once before with him. Would this affect the handbrake tho?

    I did an emergency stop on the drive and feel my foot brakes are ok. I’m off to Oxon tomorrow so fairly vital.


    Is there anything I’m missing please? :)
     
  2. Didn’t you try to remove the drums to inspect and replace the brakes last year but gave up because you couldn’t get the drum off?

  3. How many clicks does your handbrake lever make when you pull it out of the dash? Possible that your drums are properly adjusted, but the cable-yanker at the front isn't.

    Yes, theres a procedure for doing the handbrakes involving a screwdriver rotating the adjuster stars in the rear brake drum. With the wheel jacked up off the ground, bus on axle stand that side, other wheels chocked off. Handbrake released.

    Then if you can get the rear brakes just dragging when its like that, you tighten up the handbrake cables under the front by turning the square nuts with a spanner, with a mole grip holding the swaged on bit at the end of the cable just back from the threaded bit where the nuts turn. Thats until the brakes come on properly with about 7 clicks out from the dashboard.


    When you get this right the front brakes work better too, allowing more brake pressure before the pedal hits the floor, as you are not pumping a volume of fluid into the rear brake cylinders to get them across the gap where they are doing nothing.

  5. Just a thought...couldn't Sarah lie under the back wheels when you park up?

    Yes it would. The further out of adjustment the rear shoes are, the further you have to pull the handbrake lever. At some point it'll just stop working.
    The other reason your handbrake would become ineffective is if the cables seize which is very common and requires you replace them.
    NEVER adjust the handbrake cable without first adjusting the shoes while the handbrake is off.

    It comes all the way out.
     
  9. How far is all the way out? How many clicks?

    When mine does that I know it's past time I should readjust the shoes, so I do that and hey presto, like magic the handbrake is back to 6 clicks. :)

  13. My that's a long one ;)

    Adjust the shoes then tighten the cable, Alex :) The cables stretch with use, someone said to me to turn the square nuts, one turn per year :thumbsup:

  14. ^this. That's hilarious. Much further and the handle will come out of the dash :). How on earth do you do hill starts in first?

    Shoes, then cable.

    Shoes, never the cable unless you just fitted it. Just my experience YMMV. :)

  19. This .
    Adjust the shoes properly and hopefully all will be well . I'd renew the shoes IF the adjustment doesn't get the handbrake back rather than play with the cables ...

    Haynes (Not the silken haired cabby from East Grinstead) tells you which way to 'push' the adjusters as each side is different !!!
    Sounds complicated but do it once and you'll wonder what all the fuss is about
