I changed my front and rears on my v70 not long back, i used volvo pads but after market disks, didnt have a clue what disks were on it prior. Noticed no difference before or after. There is however something i have noticed, a quick double tap makes the brakes about 25% stronger/sharper/stopping power, this was the same prior to changing them too. I also feel they need a decent bleed, i know i got all the air out but they feel spongey, but hey, my handbrake works now
Volvo are a heavy car and this is my 3rd, S70, C70 and now this wee wardrobe, not had one with brakes like my Laguna's, of which prob weighed half the amount lol
