HELP! Do I have HD Brakes or SD Brakes? - Also Suspension Question

weems07 · Aug 24, 2017

I have a 2014 WK2 Ecodiesel Limited with towing package. I read online about how to tell the difference between HD and SD brakes, and my car has the vented fronts, and non vented rears, so I ordered the 330mm vented front rotors, and 330mm non vented rears, and then I start reading and I read that ALL ecodiesels came with the HD brake package, could someone have put the wrong rotors on? Not sure what to do at this point.

Also, my car does not have the air suspension, but was wondering if I have the self leveling shocks? Or was that an option, the rear shocks are Sachs 52830s.

Pic for reference

Front: It looks like there may be a gap at the caliper/rotor where a larger rotor should go?

Rear:

stick your VIN at the end of this url and get your semi-buildsheet:

The diesel with factory tow package definitely has HD brakes. I'm not certain, but I think every diesel and V8 have the HD brakes.

The rears give it away. You have a non-ventilated brake disc on the rear so you surely do not have the Heavy Duty brakes.

On the front brakes that gap that you think you see is not all that indicative. While the front calipers are the same for SD and HD brakes, you need a different mounting bracket to acommodate the larger 350mm brakes which pushes the calipers outward some 20 mm.

18 inch rims clear the HD brakes, 17s do not.
18 inch rims do not clear SRT Brembos.

Is it possible someone added the tow hitch and not the factory tow package?
