1994 C180 Euro 194,000kms. A couple of months ago I had the car serviced and the brakes looked at. Was told by the indie that the pads will go a few more months and the rotors still ok, though very thin. I reckon the rotors are really too thin compared with other makes. Are they thin when new or do they wear thin very quickly? Saw a few W202s having the rotors grounded down, mine wasn't as they appeared too thin for this. What is the minimum thickness before renewal? The indie put in 4 new sets of brake wear indicator things when they took the tyres off. Will these work correctly if the pads and rotors are actually almost worn down? How expensive to replace OEM rotors, each corner, plus whatever else is required? On dry roads, the brakes are really good, but yesterday in the wet, they didn't feel very good in stopping the car. Why didn't they put in ventilated rotors which look so thick and safe? Maybe its only 1799cc and doesn't need that kind of stopping power.
