problem :
- under hard breaking my steering wheel would shake abit, and would have some kind of "thud thud" sound in a constant manner. it is not loud but easily noticable.
- high speed driving, the wheel shakes abit also, not much but abit. usually above 120km/hr
cause of problem :
i am not sure but i think it is because i once my car spun ount and my wheels were in full lock (left) and hit a footpath. chipped my rim etc.
what could it be ?
thanks
I believe that either your rims are off balance, or your shaft is screwed cos you've got a hit on it..
My advice, get the balancing checked first, cos its cheaper..
you need a disc machine sounds like you have brake shudder,and a wheel balance -because that r(the shudder) can happen after you hit the rim.
ah yes well when i was using a different set of rim/tyres at high speed it was fine. but i didnt go heard enough to test the braking balance.
currentl rims/semi's are balanced when fitted and had the problem every since...
maybe i should try a friends rims or something
yea thats what my friend said.Quote:

u mite be imagining it also
on the cruise today, i was experiencing this to a slight degree, i think most of it was from the actual road, as it was not perfectly flat
rotors are old tho , prolly need a machining aswell
If its only under braking. Id be like 90% sure ur discs r warped.
that is the worst ****ing advice I have ever heardQuote:

this shall fix both ur problem?
4 wheel alignment around 70 bucks but u may only need 2 .. just the front.. so around 40 bucks?
machine is around 30-40 bucks...provided that if u knw how to take ur dics off...
so all up 70 bucks to fix ur problem
cheers will have a look into the problem further and possibily get a alignment asap.
where do you guys take your cars to alignment? honda dealers or any recommendations?
tyre fitting places....Quote:

fitted some oem rims today with tyres and still having the problem so i guess its not my wheel/tyre combo thats causing the problem .
most of you's sugguest its my rotor, but how would that affect my steering wheel shaking at high speeds?
also what causes warped rotors?
could it also be from bent LCA etc ?
warp rotor should make my steering vibrate at high speeds would it? maybe something else?
when rotors are warped means that the disc brakes are not straight anymore, and when they are spinning a section of the rotor gets closer to the pad then the rest of the disc, this causes the steering wheel to shake,
so basicly when the disc is moving through the brake caliper a section of it isnt even and sort of slows down faster then back to normal, then faster again
hope u under stand that:p
warped rotors are cause by u over heating the disc, and not letting them cool properly, sometime can be caused if u heat up the brakes alot then just park the car, the rotor cools down but the bit in the caliper doesnt, ie gets warped
in addition to czy sols reply...heres a senario of how it can happen.
heated up disc then running through water or washing the car straight away after a good drive.
what about his other problem i would liek to know too. i get that sometimes when travelling at high speeds my wheel shakes abit.
^^maybe ur shocks or bushes are bout gone??
how do i check? im not that great with cars.Quote:

ok i want to get my rotors checked out. do i take it to a mech and they will sort it out on their machine or how do i check it so i know which rotor is gone and take it off myself ?
do i need to do a alignment to find out or what? thanks
Your wheel alignment is out. Get that fixed. That and machine your rotors.Quote:

it most likely needs a wheel balance. that is the first point to get addressed, if that doesnt work he can look at other avenues. you may as well get an alignment + balance done togetherQuote:

but this also seems 2 sound like the affect of ABS (i dont know if ur car is equipped with ABS) but if it is, this could be what this shuddering/shacking and that faint noise is....
basically the ABS system is locking and then unlocking the brakes very quickly preventing them from locking up... - i experience going down the straight at wakefield at 150km/h and putting the anchors on after the kink...
hope this information has helped :)
thx shifty! ++
yes my car is ek4 does have abs. so maybe it is also abs ? ok well i have it checked out. i have always had abs but never this bad if it is really the abs.
how do i go about measuring the rotors ? what do you use?
you're probally suffering from brake shudder. this is normally caused by DTV (Disc Thickness Variation). this could be a result of poof fitment of discs or un even wear in the calliper or piston.
i use a micrometer (although being a mechanic i have access to all the correct tools)
im sure u can get ur hands on a micrometer through any good tool shop... it is always a good tool 2 have..
remember 2 get a workshop manual for ur car 2 so u can find out the specific measurements that u should replace the disks, pads and for much more useful information :)
Remember +PQ points :p
just get it machined! its like 15 bux a rotor, and its most likely thats ur prob as most ppl in this thread have mentioned.
just a quick before i take it to the mech on saturday.
is there a chance my disc is bent rather than warped ?? is there a difference? obviously they have to flatten the disc rather then machine it ?
is that costly?
Disc warp = slightly bent/wavy disc. :)
