Hi, i have worked on cars before etc, but just bought some new front discs for my TDI A4. I noticed there isnt a little hole for a small bolt to hold the disc on. So how do i remove the discs ?? I know the caliper will need to be removed etc.

I'm assuming these are aftermarket rotors you got from some online retailer?

After you remove your caliper, undo the present allen bolt (I think it's a 5mm or 6mm bolt... I'm not quite sure) and pull the old rotor off. You may have to pry it off with some force depending on the age and condition of the hub.

Clean up the contact surfaces to ensure they are free of rust and other dust. Simply put your new rotors on and make sure it's all the way on the hub. Re-install your caliper (Change your pads too... if you're doing them which I hope so) and put the wheel and lugs back on.

The lugs will hold everything together - It isn't 100% necessary to have that bolt on there. I'm guessing OEM puts them there so a rotor doesn't come down and kill a tech when they're up on a lift and it just fulls right off when they pull the wheel.

 

cant for the life of me get the rotor off, its the original one and its 9yrs old now... So before i damage the rotor ive give up. Put it all back on and get it to a garage this week me thinks!


Thanks for your help

This happened to me on my BMW M6. The rotors were stuck and I couldn't get them off.

I took the butt end of my breaker bar and put it in between the caliper mounting hole and the rotor itself and gradually started applying pressure. The rotor popped off within about 10 seconds. Just be careful if you go this route: You don't want to really mess up that mounting surface, nor do you want a rotor falling and hitting your leg or foot.
