Yeah i'm under the impression that my issue is relates to sticky callipers, and maybe something that car has gradually developed over time. The binding has probably been very slight, and unnoticeable previously until yesterdays incident. Perhaps the brake test that they did, or something similar may have momentary put the brakes in a more binding state? I wonder if the handbrake was adjusted (not that I could feel anything different), and if that might have caused it get into a more binding state? (guessing?) Since the incident yesterday, I have been unable to replicate the issue. Having carefully driven the car all this morning for the last 3 hours (local roads, little motorway) and checked the wheels at different stages. Used my pizza laser temp monitor on the alloys and rotors. I found the rear rotors are definitely hotter than the fronts; ranging anything from around 30C - 160C? The hub-centric rim of the alloy also felt a little hot to touch, but the rest of the alloy wheel was fine. I assume this is reasonably normal. But they do cool down to 30-50C if one simply cruises on the motorway without any brake usage for a period. So this to me sounds like i'm not getting the same binding issue that i experienced last night? Compared to yesterday, a large portion of the alloy wheel itself was hot to touch and i was only driving normally. Not really sure where to go with this just now, other than monitor the issue?

hmm difficult to say? I test drove things this morning and the issue hasn’t arisen ie whole alloy is not baking hot as per yesterday’s incident. There is some slight heat around the hub in the rears compared to the fronts. But not something I can be sure it wasn’t doing in the past? But certainly no high heat on the alloy wheel this morning? Looks like I might need to just monitor things and see how things go?

Not something i'd have knowledge in how to interpret tbh. But as I mentioned before, i would have thought serious issues such as this would have been picked up on the MOT and their service health checks to some degree? What's disappointing is the likelihood of another bill to rectify this. What can one expect in terms of cost for replacing callipers inc labour? Will try and give the car another test drive tomorrow morning, and see how it behaves.

No they never provided it. Only the MOT cert. MOT station is also Henrys.

Yup it was Henrys. Can I ask what your thoughts are on the wheel bolts and tyre pressures? How would those relate to what I had experienced? Not mechanical minded, but can't think of anything that the work would have had any impact on the issue? Would you agree? I did have the brake fluid replaced, but wouldn't have thought it would have contributed toward the issue. I assume you are referring to the issue being a seized calliper? And not handbrake related. I appreciate an MOT would involved a brake test, but would it not have picked up any issue of the seized calliper? Will probably have to call them tomorrow to see. But have a feeling it'll be a chargeable diagnose.

Hi, Just had a major service today at the dealer - 70k variable service, brake fluid replaced, haldex service, dsg service, usual tyre rotations and also an over due cambelt/water pump serviced. And to finish it off ,an MOT carried out. On the drive back home (motorway/local roads) this evening after pickup the car up I noticed that the rear driver side alloy was super hot. The alloy was hot to touch and i also noticed a slight burning smell. All the other 3 alloys were fine in comparison. I stopped, and let the car cool down before driving further (take it easy on the way back). By the time i got back home, the alloy was certainly alot cooler, so not sure if something has fixed itself or unseized? Any ideas what might have cause this? - seized calliper, or is there are issue with a seized handbrake or what? Is this something that was caused from the work at the garage; or just purely coincidence? Would it have been reasonable to think that this would have been picked up from the MOT? Cheers.
