Renault Megane Brake Issues

[Polarbear]

I took the rear wheel off wifies Megane Cabriolet to find and fix a puncture. When I took it off I was presented with this.......

Firstly it feels fine to drive, no pulling but it is the rear brake. The outer pad only seems to be half touching the disc, which is weird as you would expect it to wear to compensate.

Obviously I need to strip it down and se what is going on. I'll have to check the other side as well, the fronts have recently been done.

So, has anyone any ideas? I'm guessing something siezed but not really sure. Also, looking at the disc, I'm presuming I'm going to need to change discs and pads, both sides so I will need to order them.

Comments/observations welcomed.

I see this quite alot at work on many french cars, its normally due to the drivers not doing many miles and braking quite gently. I'd check that the sliders are free and that the piston itself goes back freely first, also check to see if the pads are worn at an angle indicating sticking the the carrier.
Those discs are fairly dear because they come with the bearings in them, pads will be cheap. Do you have the windback tool to push the piston back?

I've passed discs looking nastier than those on mots.

Cheers chaps. I'll just check everything is freed up then take it for a rant down the A5, driving like a loon while she is at work. That should cure it.

If replacing then you can't go wrong with Pagid discs and pads. ECP stock them. I'm having a front set fitted to my Transit tomorrow.
