Loud knock when braking, ST205 Options

[skogs]

When the brake is engaged, there is a loud knock coming from the right front wheel. If i brake again right after, the noise is barely noticable, but if i wait a while and then brake the same loud knock comes. I have recently changed from Tein SS to stock suspension, and that didnt affect the sound at all. Any ideas?

I would put a bet on the brake pad retaining clip being upside down.....the cross shaped thing that holds the pads steady.

Can you 'feel' the knock as you hear it?

Have you checked how easy the glide pins are moving with your caliper?

Have you checked how well the caliper piston is moving?

Does your rotor have any 'slack' that might suddenly let go under braking conditions? Like, maybe your lug nuts are not properly seated (as when using star pattern for tightening, and tightening only a small amount at a time)?

Have you examined all parts of your suspension? That is, the ball joints, sway bar link, attachment to strut column?

If the 'loud knock' is metal banging metal, sometimes it leaves some evidence, like marring.

BTW: I would listen to Nial. He knows a lot for certain.
