Anyone know the minimum thickness of brake discs for an '05 S40 T5 AWD with Dynamic Sport Suspension (part of the Sport Package at the time)? I remember seeing the number stamped on the disc somewhere, but with corrosion etc, can't seem to locate it any more.

Just as i thought, front rotors min thickness is 23.8mm (all size of rotors) and 9.8 or 8.4 mm if you have 16 or 16.5" rotors in the rear. <p>Thats at pad replacement too.

Thanks Kyle. I'm clear on the fronts, but I'm not too clear about the rears when you say 16 or 16.5. What do I measure to know what I have?

Sorry disc size can vary whether you have small brake or large brake applications from the factory which changes the spec a little.

Only the front brake rotor has size variations. All rear rotors are the same (in the US anyway).<p>See the sticky at the top for a thread with photos to help you identify yours.<p>Tom.

Oh ok, that was just the info from the spec books we get from volvo. Has specs for 15, 16, +16.5 inch brakes. Shows specs for all available markets i guess.

Re: Min Brake Disc Thickness? (tmtalpey)

Thanks, I found the sticky. So I need to figure out which front caliper I have, which will tell me what size rotor I have, which hopefully is the same as US models....then I'll know the min thickness(?)<p>Update: Had a look and I definitely have the big caliper.<p><i>Modified by tillley at 6:53 AM 4-19-2009</i><p><br><i>Modified by tillley at 6:52 PM 4-21-2009</i><BR><BR>
