karlos1987 Posted May 29, 2014 Share Posted May 29, 2014 I have got a focus mk2.5. When I come off the gas and press the brake firmly. (not an emergency stop sort of brake) I can hear and feel a metal on metal knocking noise. I can feel it through my foot on the drivers footwell. Any ideas as to what this could be? Might not be anything to do with the above but when I'm reversing left as I start to straighten the car I can hear a clunk. Any advise will be greatly appreciated. Cheers. Karl.

karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 Definitely not the brake pads mate. Only checked them last week. There is plenty of meat left on them. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...

karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 The rear brakes did size the other week but would I feel a knocking through the drivers footwell? Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
Lenny Posted May 29, 2014 Share Posted May 29, 2014 Cv joint, Does it knock on full lock? Switch off your ESP in the centre screen menu and see if it still happens Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 When I'm reversing it's on full lock yes. But the knock happens as I'm turning back to centre. Would the esp turned off make the knocking stop? Sent from my C5303 using Ford OC mobile app 1 Quote Link to comment Share on other sites More sharing options...

Sent from my C5303 using Ford OC mobile app CV joint can knock when turning mate, ESP also makes clicking noises when active so worth a try, Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 Ok mate nice 1. If turning the esp off makes no difference would you say it's the cv joint needing replacing? Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
martyntdci Posted May 29, 2014 Share Posted May 29, 2014 is it constant knocks? Quote Link to comment Share on other sites More sharing options...
martyntdci Posted May 29, 2014 Share Posted May 29, 2014 once on lock or when ever it happens? Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 The knocking I could hear started first. It happened once when reversing left just as I released full lock. Could feel this in the steering wheel. Today it started knocking when braking firmly as I come off the gas. Now I can feel the knock through drivers footwell. It only knocks the once each time I brake. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
martyntdci Posted May 29, 2014 Share Posted May 29, 2014 could it be the brakes sticking once applied then releasing on the lift off? have your pads got any movement in them to cause a noise? Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 I'll check them for movement but I'm not convinced it's the brakes themselves. The knock I can feel when braking happens whilst I'm still pressing the brake pedal so it's not on release. Is there anyway I can.check the cv joint like lenny said? I will strip down and check the brakes aswel. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
martyntdci Posted May 29, 2014 Share Posted May 29, 2014 the cv joint clicks once on part/full lock dependent on how badly worn... doesnt knock/click if in straight line etc, neither under braking...... like this Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 So looks like I've got 2 problems then? I'll check the brakes over tomorrow and report back. Any other suggestions? as I'll already have the car jacked up etc. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
martyntdci Posted May 29, 2014 Share Posted May 29, 2014 does it happen just when you brake? check ya coil springs..... Quote Link to comment Share on other sites More sharing options...
karlos1987 Posted May 29, 2014 Author Share Posted May 29, 2014 Yea just braking. I think I'll just give it all a once over and see what I find. Sent from my C5303 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
FOCA Posted May 29, 2014 Share Posted May 29, 2014 Check your engine / gearbox mounts - especially the one at the back, under the car The torque reaction from accelerating to braking can make a clunking noise with a lose/ damaged/ worn mount 1 Quote Link to comment Share on other sites More sharing options...
landy39 Posted May 29, 2014 Share Posted May 29, 2014 Would also check your anti roll bar drop links ....... if these are worn you will get a knocking when you brake. 1 Quote Link to comment Share on other sites More sharing options...
