Take off the front wheels and see that you have at least a consistent and even 2mm of brake pad lining on your pads, if all OK check the rears. Are the discs flat or scored with a lip at the edge? If so it might make sense to replace the discs & pads, while you are at it change the brake fluid... brakes are essential safety items not just for you but other road users

So are you saying it only happens just as your coming to a halt and are putting the clutch in, but not at any other braking time?

Need to rule out the clutch release bearing.

With the engine running, listen to the clutch area when someone presses the pedal down. If there is a noise when the lever moves its the clutch bearing.

But regardless of that, you need to check that all 4 brakes are OK.

Yup, that was my thinking exactly.

Although further thought would euggest that the as this happen only going down a hill, the load valve changes the action of the rear brakes, so a brake service in order.
