Have the discs turned tomorrow morning due to vibrations and pulsing, but what about the pads? Do they have any affect on this?

Thanks

 

I'd get new pads as well

 

Why is that?

Anyone else?

 

Just bc you are experiencing pulsations and vibrations doesnt mean your pads need replaced. You should be able to look at the wear of your pads and make that decision yourself. I have had rotors turned many times without changing the pads themselves.

 

No, you don't need to replace the pads, as long as they still have plenty of pad material.

If you drive aggressively and/or on the track, it's possible that the vibration is due to uneven deposits of brake pad material on the rotors, rather than warping. You can tell by seeing if they vibrate even when the rotors are fairly cold. If they only vibrate when they are hot - on the track, or when you do a very hard stop from high speed - and not when they are cold, then it is probably only brake pad deposits. If that's the case, you can try re-bedding the pads; that may cure the vibration. (Turning the rotors will remove any deposits, too, but will make the rotors thinner and more susceptible to problems.)

In any case, if you turn the rotors, you should bed the pads afterwards.

No need to change pads. X2 ^^^

 

Thankyou for the replies, the links NSXtacy provided are very helpful.

However, I do believe that I have a hub problem, or the bearing is not 100% straight in the hub as I am having problems mainly with the driver side. But until then thankyou.

 

Further upon what Ken said, if it's not pad deposit, you'll be able to tell on the first pass of turning the rotors if it's in fact them causing the problem. The high spots on the surface will be cut first, leaving some uncut surface area. As for needing to change pads though after having them turned, so long as there's still plenty of meat on them, I wouldn't. However I would still re-bed them as Ken also suggested.

 

I had a vibration issue when braking at high speeds and it was because my rotors were a bit too thin. Hopefully thats not the case with yours, as turning them will only make them thinner.
