Handbrake left on - 70mph for 5 miles - rear drum knocking

[Station]

I've only ever replaced two brake drum sets in my life, so I'm a bit stuck as to what could be wrong.The drum shoes and the drum itself was replaced by previous owner a couple of months ago.I'm driving along, lose concentration for 1/2 a second, and the dolt in front of my decides he doesn't want to go through the amber light and slams on. I slam on, smoke and skiddies etc., and stick the handbrake on, pretending as if I meant it. I and set off on my journey to the garden centre on the motorway, which is a good five miles. I notice the brake pedal is really hard, and put this down to slamming on and clearing air through the master cylinder (or something). I arrive at destination and notice a burning smell. I realise I've driven the journey with the handbrake on (explaining the hard pedal), and the drums are red hot!At the moment, I get knocking from the n/s rear drum. It's scraping and knocking, and when I apply the brakes, it actually brakes-no brakes-brakes, as if ABS has kicked in, and knocking and then back to 'normal'.Does anyone know what this is? Obviously, I will replace the pads before I drive it again, but in the meantime?

I think the friction material has probably come off one of the shoes.

Yep, Sounds like there is somthing rattling around in the drum, Also check your wheelnuts on the rear, as the heat - and subsiquent metal expansion - could have loosened them.easiest way to check is to jack the car up, and turn the wheel by hand.

Pull of the wheel an drum an inspect ... best diagnosisHad the same problem with a fiesta turned out who ever replaced the brake shoes had wedged a small piece of wood behind one of the shoes instead of adjusting themYou never know what you might find when ya buy Shite

I inspected a coupla weeks ago:

 

Whissat!

 

 

I found this:

 

 

Had been jamming in between the pad and making all kinds of bother.

 

 

Was great afterwards, if a little 'scrapey'.

Looks like the clip from the back of the handbrake lever.

What he said. Does the Haynes manual show it? Or take off the other drum and check.If a drum has got very hot it can go oval, so when it's all back together again you can check if you still get pulsing from the pedal, might be new drums needed or sometimes you can get away with a skim

it looks to me like the soft clip that is squeezed on with pliers to the auto adjusting bit that fits to one of the linings... john

Looks to me like it's a horse shoe from a very very small horse. Of course it might not be so don't hold me to that!

I no longer have the car, but it was braking fine, but with a bit of scraping noise from the drum. I made sure it was clear of horses also (I think).
