get brake vibration thru wheel and pedal though very light still noticeable and starts at around 30 mph but gets no more noticeable at higher speeds

have noticed each disc has like a black silhouette the same shape as the pads in one or two places. could this be the cause and will brake cleaner remove it ?

the usual cause of brake vibration is warped front discs, the only true fix is to replace the discs and pads. you can check the front discs by using a dial gauge on the discs and slowley turn the discs to see if there is any run out.

already tried for warps. no sign. just cant understand marks

If it's the marks I'm thinking of then they're caused by the pads getting seized in the sliders or the sliders are seized themselves

ok cleaned callipers front pads nearly due. will do pads and discs on front and try to clear rear disc marks thanks
