ZX front suspension knock on reverse

Hi,
when I start to reverse in my '94 ZX 1.9D, I get a noticable knock, almost like some play is being taken up. Going forwards, there is nothing. It feels like something is worn. Before ripping it apart, is this a classic, known problem with ZXs. I'm wondering if its strut bearings or lower ball joins.
Advice gratefully received.

This may well be the same knock BX owners experience when they stop, then reverse. The noise in their case is caused by a slight looseness in the front calipers. When they brake, going forward, the brake pads are pushed to the bottom of the caliper. Then when they reverse, the pads are dragged to the top, causing a knock. If this is the source of your noise, then it's nothing to worry about.

My 95 ZX td is starting to develop this knock too. It feels too substantial to be pads moving in calipers. I suspect a bush somewhere on lower nsf but haven't had a good prod around yet.

hi
my zx does this too, only when reversing and only on the right hand front side. It feels it is the brake, had a quick look but could find nothing strange. I'd be intesrested if you find out anything more about this.

Scouring the archives I found this previous post - I too get this on my ZX 1.9D, and had planned investigating as it sounds pretty mean!
Someone must have found the cause at some point?[?]
