Hi all

im a newby to the whole diy maintenance world but decided to give it a go changing my brake pads. I did the back first. Pads came out easy enough and the disk seemed firmly attached to what ever its attached to (didn't really check) when I moved on to the front when pulling out the pads I noticed the disk moving and with the pads removed it seems like it would just slide completely off if it wasn't for the caliper.
so my question is this are disk brakes only held in place by the wheel / wheel nuts. Ive a got a quick video of the movement but just gota work out how to upload it.

Many thanks

totally normal, the disc cant go anywhere once the wheel is on the hub.......

As above, dead easy to change the disc once the caliper is off too.

Your back disks probably wouldn't move much due to being in contact with brake shoes inside. A lot car manufacturers hold the disks in place with a counter sink screw, just not the subaru way

What car ? What brakes do you have? Brembos? If so, be aware that it is common for the caliper bolt to completely strip the thread in the brembo caliper. This is because subaru use a steel bolt to attach to the aluminium caplier. The dissimilar metals are then subject to galvanic corrosion. Then you have to reach for the helicoils .

Aye...brilliant "German Engineering"....

Quite why they don't cast in a thread, or fit helicoils themselves, I dunno.

The engineering is Italian

the only cars that do this are generally FWD and use wheel bolts so its to assist wheel fitment and stop the disc rotating, blocking the stud hole.............

And a right pain they can be when the screw siezes up.......

Very good point. All my previous cars have been front wheel drive.
