Rx 400h graunching noise in reverse

[patrick264810]

Hi new car to me 2009 rx400h  can hear grinding  noise from under the car on reversing. Seems to be from front . Sometimes nothing other times this occurs more often then not.

 Also sometimes can hear a clonk when driving and then braking usually after first drive from standstill other times seems ok . Seems from the right rear.

Currently  the car doeshave worn suspension bushes from arms left right. And I thin 1 rear disc looks scored.

Any ideas?

Other times things seem ok

Could you ask whoever you bought it from?

I had something similar. It was a large stone trapped in the guard, which was already partly disintegrated by rust. I'd guess it is likely to be a more complex issue

That is normally just a brake pad moving from one end of the calliper to the other, there should only be a mm of movement but wear or missing shims/clips can increase the gap, or even wear to the calliper itself. First would be to check all the parts are there and brake grease used correctly to stop the noise.

Another possibility is the bottom slide pin has its rubber bush missing.
