Had the same issues with one of mine and it turned out the guard was bent onto the disc.

I had the similar problem but the couse was a loose caliper. The guy in nissan service did not thighet it right and the calper fell of along with this thing that hold the brake pads and broke the e-brake cable. Fortunetly it was in a city so it happend at a very low speed.

wheel bearing?

sounds like what mine does, although hasnt been doing it lately, same as you mine stops when i apply the brakes, but i had a bakes off and checked everything, only thing i know of that needs doing in the rear is the subframe bushes, and if it is them, then the brake will stop it as it puts a constant srain on it enough to stop it rattling.

so have a look at subframe bushes while you are under there.

had the wheel off and a good poke around, then put the wheel back on. Problems still there but it comes and goes.

Specially pops up when I hit a bump!, does that help diagnose the fault abit more?

I'll have to take the caliper off another day and then the disc to check behind it, also replacing the bushes wouldn't cost an arm and a leg by any chance?

right i'm skeptical about something ( excuse the rust

)

Old disc

New disc

Is the disc supposed to move freely? I.e the wheel holds it on tight, checked today, could wiggle the disc on the left side so it hopped onto the bolts. Made me think is all thats holding it on the caliper and bolts. So if I removed the caliper I could simply pull the disc straight off....is that correct or is there ment to be something holding the disc firmly in place?

Also notice the two hole between the bolts on the old picture, how there bang on in the middle whilst the new disc has them offset, anyone know the reason why? When I was in college the discs I had to remove weren't that wobbly when you removed the caliper, fact you couldn't just pull em off with one hand.

This might shed some light on my problem but if it's ment to be loose i'm stumped. Let me know if you've any thoughts of your own, help is apprieciated.
