Technical Panda problem please help
First you need to work out if its both sides or one.
Cock the wheels one side and put the car in reverse
Release the handbrake and lift the other side rear of the ground.
Spin the wheel as if the car is in reverse then the other way.
Do the same the other side.
If it just one side you will need to remove the drum and inspect
If its both sides its likely to a stuck handbrake. Unless its been sitting for sometime.
I have had this when my Bosch pads became unglued however that's just one possibility.
Its better to diagnose the problem before ordering any parts.

Hi thanks I will get on with this shortly.
Update
I have checked both sides of the rear wheels and it is only the drivers side wheel that is locking, I have took the wheel off but is as for as i have got, I have had a little look around without taking the drum off at the back and can't find anything out of the ordinary, is it a big job taking drum off and repairing what's inside?

Removing the drum is easy enough........if it's not locked on, which yours seems to be. It could be the shoes seized onto the drum as previously mentioned or perhaps the handbrake 'locking' the shoes in place.
Can you have someone pull the handbrake on and off whilst you observe what happens to the lever as the back of the drum -see if it moves.
Beyond that, changing shoes can be a bit of a pig when you need to tension the springs - specially if you've not done them before.
If you're not confident, a local tyre/exhaust place might be a better bet.
Hi I have checked the handbrake and it still moves so I am assuming that it isn't the handbrake.
As yours is Jammed you will probably have to hit the drum as in the video and spin the drum as if the car is going forward to release the wedged shoe
The adjustment at the end of the video is unnecessary as they are self adjusting
Nothing complicated. But it does need to be done properly as critical for safety.
Its a good idea to take some photos of the springs and adjusters before dismantling.
If it won't come off, no matter how much you hit it, I've had success in the past with a big puller, just rips the drum, shoes, springs the whole lot off. Obviously afterwards you'll need a full brake kit.
Sounds like a shoe lining may have come off and is jamming in reverse, should be able to get the drum off without too much trouble if that's the case.

The drum has 6 x holes in.
4xbig ones for the wheel bolts..and 2 x smaller ones where thr 2xretaining studs go.
These 2 holes actually have a thread tapped into them...
Metric FINE ..M12 x1,25 iirc
You can use these to attempt to jack the drum from the hub.
The shoes are hold on by some skinny pins with a spring clip..
This will often ping off ..undamaged.

You could try winding a couple of wheel nuts back in and put a long lever between them.
Please be careful. It would be possible to pull the car off an axle stand.

The threaded holes in the drum should be standard 10mm. Wind a couple of bolts in evenly and it should pull off.
A likely problem is that the linings have become detached from the shoes and jamming the drum rotation. Not too common, but reported on here a few times. Mine did this earlier this year. 11 year old shoes, bonding just lets go.

I have also had your symptoms, and diagnosed one drum sticking in reverse.
It turned out to be the brake lining which had separated from the shoe, and was dislodged, causing the problem.
As I have stripped many drum brakes before this, I decided to remove the drum. It would not come off, and in the end I had to split the drum itself before sorting the shoes with a new set - plus a replacement drum.
You might have an easier time than me, but be prepared for the job to be a real pig.

Put a piece on paper on the floor behind each rear wheel and reverse the car. If the paper(s) get ripped you have jammed (wheels). If you have a helper they can tell you if the wheels are turning.
If the brake shoes have separated, You will at least need an axle set of brake shoes. However if the drums are difficult to remove they may well be worn and also need replacing. Check the hydraulic actuator cylinders. Replace both if there is any signs of fluid under the dust seals.

Well done.
