Knocking at front when braking *fixed*

[dav]

Hello all. I am getting a knocking whilst I am braking. Or coming down a hill at 10 mph lightly braking. It doesn't matter if its in or out of gear etc. Took the wheel off and everything looked ok. No stones etc visible. Does not do it whilst driving just when braking. It had new discs and pads just before I bought it. Any one else had this? My car has done 18k and is a 57 reg so still in warrenty. It's going in a week on Monday for a few other things. Cheers


** the noise is actually happening while coasting below 10 mph and it's a constant knock/ rattle until it's stopped even without braking! Driveshaft or possibly cv joint related?

It sounds like a brake inbalance or the brakes discs could have got really hot and warped! Get them to have a look when it goes in is the best bet.

I had a vibration/knocking develop at cold idle and low speed while in (DSG box) reverse, turned out to be a brake pipe which had popped its clip according to the dealer.
Not sure if in the engine bay or the front suspension area but all cured now.

I get a slight knocking when reversing and braking, but only slight

It's only become worse now cause I have heard it but it happens whilst coasting below 10 mph. Clutch in or out makes no difference. In or out of gear makes no difference. 2 weeks into this car!

I get this when braking, turning or going up and down a slight incline, i'm pretty sure its the drivers door moving ever so slightly, Seat are replacing the seal next week to see if thats the problem

make sure your wheel nuts are tight had this happen once on my first car

 

[dav]

Wheel bolts are definately tight bud, ihave looked at most visible things. Crazy.

I get what I assume is brake pads moving - noise happends like a bang/click when braking in reverse.

 

[dav]

That would be one knock in each direction? This is a constant noise which would either be a certain part of the brakes hitting the same point every rotation or something that is knocking but road surface doesn't make any difference. No noise is audible at higher speeds.

top mounts?

 

[dav]

Possibly. But that would be more of a road surface dependant etc. This happens on the smoothest of roads. I will maybe try and get it up in the air before it goes into the dealer a week on Monday.

Knowing your circumstances, I think that would be worthwhile.

So you have alot of trust in them al... Ha ha

i get knocking when braking after having my ferodos fitted. only when ive heated them up nicely though doesnt feel odd... and have no problems when braking when it does happen so not really worried about it

it could well be the wheel bearing

 

[dav]

Wheel bearing could be a good shout. It could be more of a creaking noise also as I was able to slow it down tonight. Will have a good look this week and point it out to the dealers when it's in.

do you brake harsh and heavily?if so then your pads might be on the way out and the metal is rubbing against the brake disc also it might be a good idea to check your hub bolts make sure they are tight and check lower arms and ball joints.

 

[dav]

Brake discs and pads have about 600 miles on them. Will get it on the atl at work and try that I think. Cheers


Oh and I don't brake heavy or harsh at all, haven't even drove it that hard yet!

 

[dav]

just thought i would update this. i eventually traced it down to the O/S/F wheel. Seat replaced the wheels bearing.... noise all gone!
