hi i have adjusted the handbrake adjusters and the hand brake is just above the mot standared its the footbrake i am having problems with on the back when footbrake is pressed with engine running and with out i can still turn the rear wheels with the foot brake applied even though i have adjusted the adjuster inside the drums as far as they will allow me i am wondering if it could be the cylinders on both sides as the car was parked up for over a year i am stuck and car has to go back for retest in 2 days and the brakes are the only thing stopping me.

I thought the foot brake works the front wheels (with a small amount of force to the back) while the handbrake locks the back wheels - if so, then what you have is normal, the back wheels should not fully lock with the foot brake on.

Although my dad says there should be a little valve on the brake lines to the back wheels (or it may be built into the master cylinder), which limits the pressure to the back wheels to stop them locking up before the front wheels - he suggests yours may be stuck.

The footbrake operates front & back wheels together, the rears are normally through a proportioning valve to stop the rears locking up before the front. With the footbrake applied, car stationary, the rear wheels should definately not rotate.

Does the handbrake stop the wheels rotating? If they dont it would be indicate a problem with the shoes. If they do I would suspect the rear wheel brake cylinders.

hi guys thanks for your replies i have adjusted the rear brake adjuster in each drum and the handbrake travel has now gone from 6 notches to 3 but the drums still rotate with brake pedal pressed the cylinders are not seized and freely move and there is no air lock and the shoes are in perfect condition i am wondering if it is to do with the pressure valve or somet stopping the rear wheels locking with the handbrake on the drums will not move which is correct but they do only slightly with a lot of grunt and force from me arms i admit they are hard to turn but they do turn slightly each time. i am gonna put it back in hopefully tomorow for retest and see what the mot bloke says. he told me origanly the rear brakes were only producing half what they should be at the time of mot and i am unable to test them now i have adjusted them other than turning them by hand.
