Rear brakes way hotter than fronts...
Discussion
Is it normal? Only I have been trying to get to the bottom of motorway vibrations as of late on my V60, here is a list of what I've done.
- Swapped wheels 18's (front to back)
- Wheels balanced 18's
- Swapped alloys 16's (smaller winter wheels)
- Wheels balanced 16's
- New front brakes/pads (stopped braking shudder)
- Tie rods replaced (as were worn loose)
- Hunter 4 wheel alignment
All the above has still not resolved the issue.
It may have slightly helped but...I have just noticed how badly rusty the rear brakes are, and more shockingly how HOT they are after a good drive, in comparison to the front ones, one is SO HOT you can barely go near it.
So, would this cause a chasiss vibration above 60+, under my seat and sometimes through the steering wheel?
For the price of replacement discs and pads, worth a shot?

V60 you say, very good possibility the rear park brake shoes are separating from their steel castings.
Could be rear calipers/sliders seizing of course.
Don't leave it any longer, the brake shoes have been known to lock a rear hub solid with the drum being almost impossible to remove without smashing it to pieces.
Note, before doing the job, obtain new hold down springs for the brake shoes (not the long return springs, the short ones that hold the shoes against the back plate), these wil almost certainly have stretched and now useless.
So, new discs/drums (all this assuming not electric park brake model, which i know nowt about and have no wish to), new pads, new park brake shoes and those hold down springs.

Yes, I have electric rear brake model (2013, and I hate it tbh!!), no biggie in comparison just locks pushed on the caliper with motor to lock, just little more tricky with rear caliper where motor sits (from videos seen on Youtube)...Not that I will be doing it anyway, will get my local mechanic to do it (Rear pads and discs been ordered)
thanks, will inform my mechanic on the 'hold down springs'So would/could this be my vibration under my seat/through the car at motorway speeds, I have exacerbated alot of things to get to this

Sorry, didn't think till after i'd posted it might be the later model with EPB.
Haven't a clue what the set up is like, it may not have the drum inside disc design at all, quite likely to be the rear pads provide park brake also, but as said haven't knowledge, if its EPB operating on the calipers there will be no brake shoes so no springs to replace.
Had recent similar vibration on daughter's recently bought Golf6, EPB operates via rear pads which sounds like your Volvo is similar.
She mentioned a vibration, and as soon as i laid eyes on the thing spotted a badly scored/worn rear disc, i hadn't the right diagnostic tool to put it in service mode, but luckily our local indy was able to replace discs/pads the same day she visited which was good of him...turned out the issue was a seized caliper slider, car having covered less than 20k miles.
Vibration cured.

Interesting, thanks for your reply. Yes this may sound like a very similar issue (hopefully, I am loosing my patience a little with this car Haven't a clue what the set up is like, it may not have the drum inside disc design at all, quite likely to be the rear pads provide park brake also, but as said haven't knowledge, if its EPB operating on the calipers there will be no brake shoes so no springs to replace.

) they do look rather rusty, have a lip, and run very very hot! Seems the fronts have total bias usually. I do not know when they were last changed, the car is on 103k now, so they could be original for all I know, with that kind of mileage easily being all motorway miles.
