OP whatever you do don’t go looking online for the cost of Bosch discs and pads for a Honda Jazz.
After the obvious labour costs you’ll find a chunk of the additional cost was for the disposal (which probably won’t make you feel any better).
And on that note, in a previous job one of my colleagues once used the workshop and car jacks to to change his front brake pads (plus a couple of people to also do all the actual spanner work for good measure). Once done he threw the old pads in one of the office bins, the cleaners were naturally very impressed at this very kindly dumped his old brake pads back on his desk for him to find the next morning. I have absolutely no idea whatsoever how they knew exactly which desk it was…
Anyway, just thank your lucky stars you didn’t spec some trick carbon ceramic discs, they go for about £10-£12k for you average Porsche 911 GT3 RS, lots of owners got very nasty surprises at service time… 8-0
