Hi all ive just replaced the front brake pads on father in laws corolla

Is it common on the ae102 r for the discs not to be attached in anyway except wheel hub nuts and the centre hub flange

Ive never seen a brake disc that just slides onto the centre hub and has hub bolt holes with a mil of clearance either side but no screws there are two threaded holes in the disc that i would have thought at least keep the disc attached to the hub

I'm usually involved in french cars which have a pair of equie distant posidrive screws to secure the disc plus wheel bolts that screw into the hub plus the hub flange

Would the brains trust please enlighten me as I'm a little concerned about how safe this set up is

Nope, they just slide on - the wheel being clamped on by the lug nuts holds it in place.  Very common.  Remember that 4x M12 wheel nuts done up to 100Nm torque gives you ~13 tonnes of clamping force on to the face of the rotor hat - that sucker ain't going anywhere.

The two tapped holes you see are for jacking screws to help remove the disc if it happens to get seized in place by rust or brake dust.
