I recently needed to replace my front discs and pads on my mercedes. I opted for the Brembo brand as they included replacement bolts and hardware. After fitting the first disc pads and pad clips the discs had a intermittent grinding noise. On investigation the replacement brake clips were not the right size. The internal gap on the clip was too small and allowed the disc to contact the edges. I had to re-use the old clips. The photos show the different gaps. The old one on the left has the correct gap where as the new clip on the right is far too small. Disappointing really considering the difference in cost of the Brembo brand to the others supplied by GSF.
