Pulsating brakes
Does any one know why my brakes pulsate when i push the brake pedal at speeds of over 50km/h. The whole car starts to shudder at speeds over 80 when i brake, even if its over a long distance...

Sounds like your discs are warped. You can get them machined flat again, or you might have to replace them.

Might be worth your while checking out that the disc is sitting flat against the Hub Face before you go spending too much money - if the pads are new it's possible the disc has cocked sideways a little and may not be running true...
You can check this by taking the wheel and disc off and tidying up the front face of the hub and the back face of the disc with a wire brush. At a guess I would say they'll need machining/replacing but it's worth checking IMHO. |

Thanks for the help guys. I've just made an appointment at a local mechanic who told me exactly the same thing as u guys. It is going in on friday at 8am and should be all done by 10 at the latest. Cost is 125$ but it includes some other bonus **** and i get a discount there when i pay due to other stuff so it should get reduced to 80$ for the car.. Thanks for the help
