Sorry for the long blah blah this time.
On going with the deep clean/detail of my car I got to the point of doing the wheels.
Someone in the past (not me) had possibly applied wheel acid cleaner and left it on for too long so it etched into the lacquer.
Before
After
I'm pleased how they have come out, however while the front ones were off I thought I'd check the size of the brake discs, they always looked under size to me with a large amount of the stone guard showing.
Sure enough when measured 320mm, standard on the B8-8.5 S4 is 345mm so 25mm too small.
Original top, new (correct size) bottom
The pads didn't fair to well
They were genuine Audi/VAG parts, I have been through the (full Audi) service history and there's no sign of the car ever having replacement discs and pads (mileage currently 23000 miles), could it maybe have left the factory with the wrong setup?
Fair play to Eurocarparts in the current circumstances as I ordered the new discs and pads Thursday afternoon late on for next day delivery (social distancing) and they were delivered by 08:30 yesterday morning.
All sorted
No caps on the nuts as I hadn't torques them up at the time.
Today I start on the inside, first off removing the Limo tint from the back screen and rear windows (can't see feck all at night when reversing!)
