Re: Grinding/Judder through break pedal
Any surface rust should wear away within a few miles of driving. It may be the corrosion on your discs is too deep or hardened.
It may be the case a new set of discs and pads are required.
A 30mm socket tends to fit many models but I have came across 2 or 3 variations so it may be wise to measure what is fitted to your car. I have even seen two different sizes on each side probably because the vehicle in question has previous repairs.
