knocking coming from the back?

[sum-dj]

Clio 172 2002. Seems to have developed some God awful knocking that sounds like it's coming from the back. When I roll away from my house down hill I can notice it quite badly and under braking at low speeds. Doesn't seem to happen, or I can't hear it when I get above around 20mph. The noise is quite rhythmic too kind of in time with the wheels turning, it doesn't just happen randomly. Has something come loose or not been done right when I last had my read brakes done maybe or could it be something else?

Took mine to the garage with the same problem, apparently I need to replace my rear discs and they are badley worn.

Hmm sounds like the problem I'm having. I can feel the clunk under my feet though sometimes.

Shock absorbers probably leaking oil and needing replaced.

I'm unsure why anything braking related would cause knocking.

Other things to check for are wheel bolts done up correctly,play in wheel bearings,damaged/missing spiggot ring if not running OE wheels,loose heat shield above rear silencer,rear silencer hanger collapsed,play in the rear arm bushes,badly aligned exhaust system,worn rear shocks/bushes & worn/corroded rear discs.
Good luck.

Thankfully for replies. I only had rear brakes done at the end of last year so surely can't be worn discs? Also the bearings come pressed into the discs so guessing it can't be them? Will get everything else checked that's been mentioned though. Thanks a lot.
