Hello, newbie here as I am a Honda guy. Good morning, what size allen bit do you use for the caliper pin bolts for the front and rear caliper pin bolts on a 2018 XC90 T6 Momentum? Been getting conflicting results from the Volvo YT videos as well. Thx for any inputs shared. BTW, this is my sister's suv so I have to do it. Duty calls. I know the caliper bracket bolts are 18 and 15mm front, and rear. Everything is *** backwards compared to JAP cars.LOL

 

lol, when I owned an Audi, everything was an odd bolt size 15,17, 19 mm and they loved to use a bolt head known as a "triple square" (not the same as a torx). Then when I started working on my Volvos, I found I needed 16,18 mm as well plus a full set of torx bits and some odd allen heads (as I recall the 850s required a 7mm allen for the front brake's pin. Looks like you get a free pass to go to Harbor Freight!!
