Me and a mate have just changed the front discs and pads on my 1990 325i. Wanted to say thanks to all on here because the guidance posted made it a straightforward job for a mech. numpty like me. We had it all done in 2 hours!
The allen bolt on one of the old discs wouldn't budge but one lump hammer used with two big swings sorted it beautifully
I can now brake from speed without the wheel trying to shake itself out of my hands.
