Hello,
So it seems my car has developed a knock when I brake at slow speeds this only started happening a few weeks back coincidentally after I went around some corners quick. All bushes are nolathane and relatively new. It's doing my head in and I'd really like to fix it before anything bad happens. Cheers

The car is a 1999 liberty heritage

Video looks like a "knock when pressing brake pedal" ?

Just crawl under there and wiggle it with your hand to see what's got play in it. Pedal bush, pedal bracket, clevis pins, master cylinder operating rod or master cylinder mounting.

Sounds to me from the vid like something loose or worn around the pedal/footwell area

it does sound like its in the inside in the video but if you stand outside it sounds like its coming from the drivers side wheel somewhere in that general area i forgot to mention that when i put it in drive and the car rocks forward slighty it sometimes does it or when i accelerate after stopping at light etc

Maybe check the lower control arm bushes.

Agree with everyone above.  I presume you've checked for a loose caliper or a wonky brake pad but I'm clutching at long shot straws with those suggestions.

 

My old Gen2 RX had an odd noise & the pedal felt a little loose/mushy so I looked under the dash and just about every bolt holding the brake pedal to the firewall bar one was sitting at most in by a couple of turns of thread. A few appropriate expletives were said followed immediately by finding my ratchet socket set & tightening of them.  Much better after that.
