My recently acquired 430, with the M+ blue 4 pots is squeaking every time I pull it up to stop. It's become incredibly annoying!
I have had this on other cars, and am well versed in how to bed in brakes. I have carried out the procedure twice (10 x medium braking 40 - 20mph, 10 x aggressive braking 60 - 20 mph to the point of almost tripping ABS, then a 15 minute cool down run with zero braking), and each time it has solved the problem for a day or two, then slowly but surely, the squeak returns
I don't get what else could be causing it? Pads look fine, the car has only a little over 20k on the clock and looks/feels very well looked after in general.
What else can I try? As it stands wifey is starting to give me the "You've bought a silly broken car" look. I need to solve this before she loses her patience
