W201, 190e brake pad replacement

[Guenter]

Hi, I've searched the forum but could only find an excellent reference to W124 pad replacement. Inspecting my 190e I see that the brake calipers are quite different. The caliper appears to be in two parts, held together by two 13 mm nuts top and bottom. these bolts have small bellows on them presumably as the brakes are applied etc. I also see two 19 mm bolts top and bottom that appear to hold the caliper assembly onto the wheel itself. Do I undo the bottom bolt and simply try to swing up the caliper to get access to the pads, or do I need to remove both of these 19 mm bolts.

I did see repeated reference to 17 mm nuts..... can't see these on my '93.

any help, pointers and/or information much appreciated

cheers, guenter
