Front pads uneven wear Audi 100 - Mapmaker
Changed the front pads & discs on my late Audi 100 yesterday, and was astonished by the variation in wear. IIRC, new 10mm; replace at 2mm.

Remaining material:

Left inside 1mm
Left outside 3mm
Right inside 3mm
Right outisde 5mm

What should I deduce from this? Or is this sort of differential normal?

Thanks as ever.

I usually find most wear on the piston side (inside) of my brake caliper, and sometimes left/right differences like yours. I reckon unless you free everything off once or twice a year, corrosion and dust builds up, preventing totally free movement. Hence preferential wear.
