In the last few months, I've replaced pads on my 83 300SD and then on my 93 300E 2.8. The 300SD pads squeeled so loudly, within a day of installation, that the mechnanic replaced them instantly. The 300E pads have been squeeling intermittantly and I'm about to bring it back. Squeeling is high pitched, under light braking. I've never seen this problem this often, and my 300SD eats pads. Anyone else having problems recently with Mercedes pads? Has Mercedes, perhaps, changed something recently?
