I bought a pair of brake pads from aftermarket and trying to replace them. But there is a problem. After you take out the tire, i think there is a bolt or something holding the brake pad with the base.
Does anyone know what kind of bolt that is?

 

I am about to replace my front pads and rotors (01 S60 NA). I came across this item from ipd http://ipdusa.com/Volvo-S60/Brakes/7.../p-74-391-365/its an odd-sized hex bit and I don't know if any local places stock them. You can get one from ipd for $5 plus sh.

 

Yup. 7MM HEX
