A daft question, but how old is the brake fluid? If it's a bit old could the moisture content be playing havoc eith heat cycles? You've presumably done a full flush but worth an ask.
Otherwise check the pipes for kinks/dents. A friend had a horse box where the brakes stuck on, after replacing every part of the system other than the lines i took a look and found damage to one of the lines. The dent was acting like a 1 way valve and slowing brake fluid returning thus keeping the brakes on slightly. 1 replaced line and all was good.

Another thought, what's the wheel bearing play like when it gets warm?

Thanks for the thoughts, the whole braking system is ~2yrs old. Literally all new, top to bottom. So it shouldn't be anything aging...
The rear bearings are newer still, they gave up late last year and were replaced in September iirc

"...the anti-squeal shims are fitted, they're plastic ones." hhhmm never come across plastic shims, still, 'everyday is a school day'
"It's weird, definitely points to being heat related as it only comes on after 5-10 miles of driving." perhaps the plastic shims are 'softening' and becoming ineffective ?

That's one of the pics I actually took  You can see the plastic anti squeal backing here. The squeak isn't really a squeal; the noise happens when moving and seems to correlate to wheel rotations(e.g. squeak, squeak, squeak rather than one long noise), with no brakes applied. It goes away when the brakes are applied, rather than a pad squeal that would happen when the brakes are applied. I wish I'd taken it for a spin last night, but I didn't get a chance |

If it's squeak, squeak, squeak doesn't that mean the disk isn't flat?

Following this closely... our old Merc camper developes a squeak squeak squeak after being driven for a while, only in a straight line though.
It goes away on corners or if the brake is applied gently.
I assume the bearing has a bit of play and the pads rattle about, not that I have had time to jack it up and check.
I'm prepping it for test this weekend though, this thread has given me food for thought.

one other thought, given the aftermarket mounting kit is the calliper perfectly true to the disc, try a feeler gauge under the pad and see if there is a noticeable difference in clearance top to bottom and side to side.

This is probably not of use to you, but I had the exact same symptoms from the brakes on my car. Calipers were only a year or so old... Tried fiddling about with all sorts of random things and backing pads etc like you are... Turned out the pistons had corrosion already.

Time for an update! The car had sat in shame pretty much, I had a holiday booked for the first 2 weeks of August and frankly had enough of pi$$ing around with the brakes. I managed to book it in to RACE in Charlwood for the day after I got back, having swung by after work and discussed the issue with them. That was today! Luckily I checked the car last night as I'd left the battery connected for 3 weeks and it wouldn't turn over. Overnight charge sorted that oversight... They checked disc to caliper alignment and essentially put it down to the lip on the pad where it was overhanging the disc outer diameter. So they heavily chamfered the pad and tested it best they could. I've just got home and safe to say I think it's cured it. Slightly annoying that it was a cause I had thought of, but given up by that point. So now everything's good right? No I opened the garage door this evening to be greeted by something between a drip and a puddle of red fluid. Thanks a bunch gearbox...  Looks like it might be from the rear seal? I checked the fluid and it was on max, so I'm not tooooo worried yet. I've put the drip tray underneath to see if anything else falls out. Hoping to still keep using it more though! |

Just a thought, could the box be a bit too full at the max mark causing it to leak/push out past the seals? How does the dipstick fit to the box, is it direct on to the box or via tube fixed with a rubber coupling (like the later MK2 Jags?). |

Is it a C4? Dipstick tube and band adjusters are common leaks on those.

How does the dipstick fit to the box, is it direct on to the box or via tube fixed with a rubber coupling (like the later MK2 Jags?). It's direct into the box, see a few pages ago when I replaced a rubbish aftermarket one. This is a steel tube straight into the box with a blade type dipstick. Is it a C4? Dipstick tube and band adjusters are common leaks on those. It's an AOD. I had a brief look under it and there's some drips and wetness around the tail housing and the cross member but I didn't take any pics, or couldn't get any meaningful ones anyway... I'll check the tray another evening this week and do another level check too. Thanks guys for your inputs! |

Oils are a buggger.
They spread and look alarming, and sometimes it is a temporary thing before seals settle.
I guess use can generate a drip too, again, these sometimes self correct.
Fingers crossed.

The latest on the trans fluid is that there was one drop of engine oil and one of gearbox fluid when left overnight. I'm going to keep my eye on it, but no panic currently... I'm going to pop along to the Redhill cruise on Saturday, and would love to cruise with all the windows down. However my headlining is drooping at the back and the wind gets behind it.  Before RRW I did a quick and dirty with some gaffer tape, but this is giving up.   So I bought some green faux suede to try and fix this  Here's a long piece cut and pegged together before stapling  And starting to attach to the existing material   This is where it stands as of last night, loosely in place. It should end up much tighter when it's tucked into the rear seal. More to do this eve!  |

I didn't get a great deal done that was picture worthy last night, but I did get stuck straight in this morning. Here are the side panels, both attached at the join with the long centre piece    Once they were attached and I'd done a final trim, I could start tucking it in  I ended up doing a double pokey method  One trim tool to open up the seal, the other to do the tucking  I worked out from the middle, then down the sides of the screen and then it tucks into the door opening trim too. Like so  And the finished thing:   A bit like the dash, it's not perfect, but I did it myself for the cost of 1m of fake suede and a new pair of upholstery scissors (a revelation btw) and it's about a millionty times better than before I also decided that this morning would be a great time to wet sand the patchy roof paint.  Halfway through...  And after...  Again, it's not perfect, but much much better and not a major annoyance any more Next up is trying some proper whitewall cleaner then off to Redhill around 5! |

Headlining matches the seat detail and door cards nicely.
Had a squeaky brake like that, turned out to be the friction material was too soft and was collecting road debris which would embed in the pad and squeak as it touched the disc (which are never 100% true in a daily driver).
Resolution was harder pads made of non organic material. Nothing stuck to them and they had the bonus of being less dusty.
That oil leak is normal. I haven't seen an American automatic gearbox built before about 2005 that did not leak. That's how you know it has oil in. Both mine leak past the tail shaft seals, when hot and after sitting for a few days when the connverter starts to drain down and overfill the oil pan.
You should see my driveway. Looks like a 1960's parking lot with the big oil stains.

Phil Thanks Phil, I tried to get a material that complimented what's there as matching it for an 'invisible' repair would involve buying material from SMS and then being much neater than I have the skills for. The leak makes me feel quite a bit better, it has sat for some time before doing this, after getting nice and warm. Cheers |

That headlining repair is so impressive, Tony.
I’m still psyching myself up to sew the button back onto my work trousers…
