Replacing rear disc only?
Discussion
Hi all!
My MK6 Golf's rear discs require replacing, however, whilst I know pads and discs are supposed to be replaced together, my rear pads are almost like new (even though they were both replaced when I brought the car 3 years ago) and appear to have a lot of life left in them.
The car is currently only used for city driving so the bedding in of the old pads to the new discs I don't think would be an issue, but then again what do I know?
Honestly the rear pads have so much life in them it'll be a waste to replace them, but before I decide I thought I'll run it by the professionals? Thanks!

Generally a very false economy to not replace the pads, unless they are perfectly flat with no uneveness whatsoever. The slightest wear pattern will transfer to the new disc.My MK6 Golf's rear discs require replacing, however, whilst I know pads and discs are supposed to be replaced together, my rear pads are almost like new (even though they were both replaced when I brought the car 3 years ago) and appear to have a lot of life left in them.

I also do not recommend cheap pads, but on the rear of a vehicle that is mostly city driving then a cheap pad that will wear quicker is probably better for the brake system than a slow wearing pad. The quicker they wear the more the calipers will be moving and less likely to stick. The downside is that cheap pads often make a lot more dust and potentially more noise.

Why do the discs need to be changed if the pads are almost unworn after 3yrs?
I can guess some answers, but what does the OP say (or what have they been told)?
this...presumably calipers or something are seized ?I can guess some answers, but what does the OP say (or what have they been told)?
But if the pads are good quality, plenty of life, no deterioration at all....probably no real reason to change them. Certainly say if they were old but very good OEM pads, I'd sooner use those than some new spurious aftermarket pad.
More investigation needed either way
Whilst its ok to fit new pads to otherwise good but ageing discs, i've never done it the other way round, if the discs need changing there's no doubt an obvious wear pattern on the existing pads which may cause permanent tram lines in the new discs.
Daughter's new, to her, 16 plate mk 6 Golf needed new rear discs despite having covered under 20k miles, one disc looked awful like a 100k miler, usual cause of the brakes never having been serviced since new so one pad seized in place, never considered reusing the pads.

The trouble with not replacing the pads is that the rust crust on the inner and outer diameter of the old disc (or anywhere else on the disc) will have crept into the pad swept area leaving grooves in the pads, due to the lack of contact between the old pads and the new discs in these areas, the new discs will soon look like the old ones as rust will occur in the same areas.
