Rear brakes creaky?

Following from my previous:

I've got a creaky brake on the rear of my 2007 Honda Accord Tourer i-CTDi, and the Accord forum aren't very helpful, so I thought I'd ask you wizards.

 

Basically when I brake I get a creak from the rear in time with wheel revolutions. It happens turning or not, and from the slightest hint of braking to quite hard - beyond quite hard it goes away. Usually one creak per rev of the wheel, but sometimes a second creak each rev, as if it's rebounding in some way. The noise itself is a creak, imagine a creaky gate, if you push it REALLY slowly you can hear as the hinge 'snaps' to each new friction point, putting all these 'snaps' together you get the creak - that's EXACTLY like the noise I'm getting .

 

 

I took it into Honda and they diagnosed it as needing a rear offside caliper (£400!!) and both rear discs (which are "knackered"). £650 with fitting and VAT.

 

I can't help but think they're bulltishing me though, there's apparently some history of sticking caliper from the previous garage, who "unstuck" it and changed the pads, when they should have changed the whole lot. The discs have that corrosion stuff around the edge (which I didn't think was too bad, but what do I know) and they say that's causing the donk donk noise on right hand bends, as the weight changes - sounds reasonable, I'm not too bothered about having to change the discs as it probably should have been done with the pads - plus if it is that I don't have to get the CV joint done that I thought was causing it!

 

It's just this caliper thing I can't get, it definitely sounds like a creaky spring, not a pad rubbing on some corroded disc - plus I just did a 30 min drive on dual carriageway (with noise before and after) and both rear discs were stone cold, OK so I exaggerate; they were too hot to touch for more than a few seconds, but the hubs weren't radiating like I've had before with a sticking brake.

 

So what do you think? I'm going for a second opinion at my local independent soon.

 

 

Here are some tech pics of the rear brake setup, the handbrake shoes are inside the disc hub and I reckon it's something to do with the handbrake getting caught, so when I add any friction to the disc the handbrake shoe springs are 'pinging' in some way.

Not if theyre siezed off, the brake pressure would easily overcome the locking effect. If youre mechanically minded remove the caliper and clean/grease the sliders, see if that helps. Out of interest does the handbrake operate the caliper like older Hondas or is it inside the disc as per Supras?

Siezed may not be the word, maybe stiff. Warped disc would give a roatation related creaking noise under braking if the caliper sliders were stiff, and probably shut up if you stand on the brake pedal. And as far as a 'donk donk' noise goes, if my brakes made that noise I wouldn't be driving it! That sounds more like a ball joint/link bar issue.
