Squeeky Rear Brake

Hi all, some of you might have noticed (Tom has at least) that the rear brake on my STR is squeeky. When I took the bike into the garage for its first services I mentioned it and they said and I quote "the rear brake just needs greasing", this sounded a bit dodgy to me but whatever they did worked...however they are now squeeking again worse than before...can anyone shed some light on what it means to grease the rear brake and possibly explain how to please

 

When braking or when moving the bike?
When pushing the bike, it's the pad is slightly mis-aligned / burred - pop the pad out, file the edges and pop back in.
When braking, it's lack of copper grease on the back of the pad - pop pad out, apply copper grease, pad back in.

 

As its under warranty i'd take it too the shop and get them to sort it Russ, just so ther's no problem re invallidating any warranty. (im assuming it is under warranty).

 

The problem is that the monkeys these places often employ don't actually do it properly. The bosses don't mind because the owner will be back soon enough to spend some more money. I had a similar experience with the brakes on my Subaru lasting 1,500miles or so - I'm particularly kind to vehicles (original clutch plates on Land Rover still good at 110,000 miles, and on the Scooby I've done 100,000 since I bought it with no sign of a replacement being needed) and it emerged the mechanics hadn't lubricated the block carriers, so the pads just tipped forward and wore out one edge to the metal. The next time I demanded the old parts back for evidence and refused to pay for the replacements. Much grumbling at the counter but it was done properly...
