Your linings look to be brand new old (asbestos) stock. So the contact area on the drum will be minimal which is why your brakes are useless. There are a number of ways to get the new linings so that they have a good contact area with the drum but all involve the removal of some lining material. Given that this contains asbestos, you might well prefer to have modern linings fitted and then persuade them to fit the drum properly. But the modern linings may not work as well as the asbestos ones, once bedded in.

John, have you thought about chamfering in leading edges of the shoes, generally improves braking.

IF you substantially reduce the area of the trailing shoe it will work much better, Originally it was softer, allowing it to wear faster and apply more force on the leading shoe which is the most effective. Best are TWO leading shoe but don't stop you rolling backwards Nev

Thank you for your comments people.

Photo shows the linings, surface of which almost looks as though it had been polished, dead smooth.The plan is to have them relined maybe a little over size and then as Paul says remove a little of their surface to get a good match to the drum.

Removed the rear brakes today and they are in no better state than the front. As you recommended they are in the post to Villiers Service. I have used them before and have been happy with their service.
