My own story has also involved brakes and unfortunately an expensive one.
All discs and pads have needed replacement due to corrosion, stuck sliders and anything the tartan climate has been able to throw at them. I also think the deterioration has been helped by my keeping a cover on most of the winter, especially after assiduously washing the wheels "right-the-way-through" as is possible with the Momo's fitted.
Yes I do dry them off after hosing the shampoo away but I guess the lingering moisture on the discs didn't have enough air circulating around them with the car cover stretching almost over the entire wheel.
Also not improved by one or two periods of 3 or 4 weeks not taking it for a drive (using Mrs Ed's Seat Mii instead) and allowing the mechanics to become seized
I was lucky to have been gifted a new set of Pagid front discs and a set of OE Fiat pads so I only had to pay for the rears (which my chap decided to get more Pagids for). He commented that the rears basically hadn't been working at all
A lesson hard-learned; but it's reassuring to be safe again. I also learned that the Pagids are "coated", not something I had come across previously...I guess this means they might be less liable to corrosion?
