Since I uprated the brakes on the GS to the above spec, I have found they feel, through the pedal a bit like you can feel the grooves in the disc. if I brake hard continuously the more I brake the greater the vibration through the pedal but also through the whole car. I know they are a performance mod but should they upset the ride that much?
I wondered if it was because the anti-rattle springs are not replaced when the EBC pads are fitted. could it be the pads are moving in the caliper?
If not, what to chuff could it be?
