*Advice needed* Intermittent squeaking
Discussion
Bit of a head scratcher this one - noticed an intermittent squeaking coming from my rear driver side wheel.
Upon inspection, in addition to the usual brake dust there is some metal dust which has rusted slightly, presumably due to the wet weather.
My initial thought is brakes but I had new discs & pads on the rear less than 5k miles ago. Pads look okay, no unusual wear apparent.
The squeak is not constant and seems to vary - sometimes between 20 - 40mph, other times at 50mph+
Tried giving the brakes a good spray with a pressure washer to dislodge any dirt/stones that may be lodged but no joy.
Got a long trip up to Scotland on Sunday so would like to try and fix before then... any suggestions?

Could be a dust guard behind the disc is slightly out of shape and you only catch it occasionally which is common.
I had a rear brake noise on a gen7 celica that had new discs fitted and it was the offset of the handbrake shoe inside the drum had bedded in and moved enough to let the shoe touch the drum when the handbrake was off. Try resetting the shoe offset if its not the dust guard (if you need info on doing this come back to he thread).

Not a clue how to reset the handbrake offset!

The offending wheel is most definitely hotter than the others so seems likely to be a sticking calliper which I'm not thrilled about.
Haven't messed around with brakes on a car before, always let a professional do them so not too confident to fiddle around with this myself...
Take it to a professional then, and they can give a positive diagnosis at the same time in case it is a sticky caliper. If you can't do that then the method is-
To set it, jack it up and take the wheel off and release the handbrake. There is a rubber blanker in the hub, pull it out. Behind that is a brass wheel with chunky teeth. Put a small flat screwdriver into the teeth and wind it upwards a fair few turns (6-10) until you can't move the hub (by hanging the wheel on the studs and using your hand to turn it). Then wind it back down 7 or 8 teeth and that is the correct offset to not touch the drum when the brake is released. When you're done pull the handbrake and check that the wheel is immobilised (again by hanging the wheel on the studs using hand force). Take it for a test drive and make sure the noise is gone.

Dropped in to my friendly local indy to see if they could help - popped it up on the ramps and it seems that the 'floating caliper' wasn't floating.
Quick strip down of the caliper and re-grease has sorted the squeak, going to need some new pads though as the incumbent one has worn down quite heavily due to the caliper not moving properly.
Thanks all for the contributions and suggestions

If it’s anything like an e46 the disc backplate will rust around the securing screws making it chatter, rattle, and rub the disk not always in that order. I rectified mine with some thin penny washers but it really needs replacing but then so does the whole car 
What is happening there is the clip holes rust to become oversize, and the securing pins (not screws) become loose. These pins hold the rear parking brake shoes (a 'drum in hat' system of drum parking brake inside a brake disc). The parking brake shoes then are held by the ends only and the shoe is pulled outward by it's retracting springs. The result is that the brake shoes' metal base contacts the drum, instead of the braking material, when the brake is off. Thence the squeal/scraping noise. That is the E36/46 issue. It may be the same on OP's car if the set up is similar.Gassing Station | Suspension, Brakes & Tyres | Top of Page | What's New | My Stuff
