W203 03 C200K rear suspension shudder when braking

First time posting but have read this forum on and off for years.

Better half’s car now. I drove it for first 5 yrs. Now has clocked up 400,000kl. Been a gr8 car for sure.

So the issue: Rear suspension shudder occurs when braking mainly when driven down a long hill with the brakes applied reasonably gently to slow the vehicle. If brake hard it does not shudder.

It does not come through the steering. And now I take careful note, nor though the brake pedal (so was not rotors in the first place).

Okay, so at first I was sure it was the rotors. So got them both machined and checked. One was very slightly out.

But shudder is still there.

Searched web and forums. Tried a few suggestions without success.

I jacked each wheel and checked for any play. Tried rocking the wheels laterally and vertically. No movement.

Climbed under and twisted and wrenched, then with a bar and pushed on things, nothing obvious.

So now I'm at a loss and need some more specific suggestions please.

Many thanks...

Thanks...

caliper pistons appear to be OK.

Crack in the axle subframe. I'd need to check that one.

Hi,

Wondering are there any other suggestions...

For example, what part/s should I be checking with this problem in mind?
