knocking noise?

[AngerManagement]

Hi,
can any of you switched on cookies help me with noise problem.

Every time i apply brake, there's a knocking noise coming from my front passenger (n/s/f) wheel which knocks on every rotation, i will be changing pads this week but until i have a good look i dont think this will solve the problem...........any thoughts please?

regards Stewart

could be the brake rotor/disc fuc**d??????? other than that more info needed.....your going to have to get your hands dirty too many variables.

Pads worn down to damage the disc.. or a trapped stone maybe....

[mattyme]

possibly a warped disc.... can you feel uneven brake pressure on the pedal or steering wheel?

Thanx for replys,

changed pads but noise still there, does any1 think i should change bearing and disc even though disc's looked fine and wheel has no play in it?

By the way,  i've never heard of it called a rotor until now, is that a new thing or am i that naive (stupid)? :?

+ a mate of mine said something about a U-joint......any1 know much on that??????

can you be more specific with the model you have.....
so.........let me get this right the noise is only apparent when brakes applied??? you have changed the brake pads and checked the brake disc (rotor i have been dealing with the americans a lot lately with my brakes) and wheel/tyre is faultless and serviceable....can you feel any feed back through the brake pedal when pressed? or the steering wheel? and noise from n/s/f apparent???? is the noise a high pitch clicky knock or more thud type metallic sound? do you have any upgrade parts fitted to the axle?
the uj is a 297 i believe you should also check the hub carrier wile your checking the uj
that should keep you busy tonight.....

When i apply brake it makes a thud type knocking noise as wheel rotate's & with the rotation, and yes braking is a little inconsistant, the vehicle is 93' L-reg 4ltr high output Ltd Edition and not mod'd in any way i can see! noise comes from front left wheel though it does sound as though sometimes it also sounds more central as well, though this could be me going slightly mad from try'n 2 work it out!
Will av2 get my mate 2 look in2 the hub carrier though.

ok....on your description by feeling it through the brake pedal it must be disc/hub or bearing related....when you checked the disc earlier did you look (very closely) at the air vents in the centre for corrosion sometimes these can collapse and give the feeling of a warped brake disc......although it looks good until under braking  pressure....any heat spots on the brake disc?????
