The cables that operate the park brake are self adjusting ,but not in one but TWO areas.The rear pads or shoes are self adjusted to keep correct clearence from the rotor or drum.The second 'self adjust'Re cables,is the part that most don't understand.The biggest issue seems to come when the rear cables that go to each side need to be changed.This is a common fault on the disc rears as the cables get water inside and sieze up.The problem seems to come when trying to connect the new rear cables to the single cable & balance beam that runs from the lever...not enough slack in the short cable to connect the rears up....This is where the auto adjust function needs to be understood.(Please look at the pics)The handbrake lever has TWO ratchets and pawls,one is the one you feel 'click' when you pull up the brake,the other is the self adjust,on the pics the red is auto adjust,the green is the normal click ratchet.Before you attempt to remove or fit rear cables the short cable from the lever needs a lot of slack...To relieve the auto adjuster you will need a buddy under the car...The lever must be fully down in the off position,the red pawl must be lifted away from the ratchet...at the same time under the car the short cable and balance beam is pulled rearward.Once pulled back as long as it will go, release the pawl and the short cable will stay the the long 'unadjusted' position..DO NOT PULL THE HANDBRAKE LEVER...as this will re-adjust and take up the slack.With the slack at the balance beam it's easy to unhook the two cables etc and fit the new ones.once the new cables are in place and locked in the elongated holes in the beam...pull up on the handbrake....the self adjust at the red ratchet will operate and take up any slack in all 3 cables....easy eh!!!

One final point...If you continue to use the park brake with siezed rear cables two things can happen as you haul on the brake lever 1)You can damage the short cable from the lever 2)You can also damage the self adjust on the lever...Worse case this could result in a new lever assy.If you have issue with the rear cables DON'T haul on the lever like The Hulk...fix the rear cables before you cause more damage...
