W202 C280 Knocking from rear when breaking?

[Big Dan]

Hi All,

I have just bought myself a 1996 C280 and am just ironing out the niggles.

Front brakes have just been renewed but now have a noticable knocking from the rear when breaking.

The noise seems to be happening as the wheels turn to the same point on the axle and as I slow down the noise is quite regular/repetitive in that you can tell hen the next knock will occur.

Seems to be coming from the rear and I can feel it through the car as it knocks.

Any ideas what this could be???? (i.e. what its gonna cost me! )

Should have said its an elegance model with standard suspension and wheels not lowered (yet).

Bloody laptop!!

Should have read "Had to slam the brakes on today but no sign of any knocking?? However when braking normally the knock was back??"

Got a funny feeling its gonna be a warped disc on the back as I kind of answered my question myself by saying the noise is quite regular when slowing down would guess thats worst bit of warping on the disc knocking back against the brake pads.

Find out tomorrow.......

Still haven't managed to get back into the garage but have noticed the knocking can be felt through the brake pedal?

The car itself is stopping properly (luckily ) but as I'm braking theres this knocking through the car and the brake pedal pushes back against my foot?

Any ideas?
