Re: Brake vibration

[C M Smith <cmsmith@domain.elided>]

I don't know what brakes the GTV6 uses but a common source of vibration 
where the rotors are true (warped rotors are obvious and easy to check, 
with the suspect wheel off the ground and an assistant or a brick to put a 
little drag on the brake, though those inboard rear brakes are a challenge 
to check on the GTV6) is sticking calipers or caliper guide pins whichever 
type of brake you have. The symptoms of sticking pins or calipers are  a 
grumble or rumble felt more than heard through the brake pedal. Braking is 
unaffected just the sticking caliper vibrates as the run out of the rotor 
causes it to move a fraction side to side. Check the pins or caliper 
sliding faces and if they are grubby, clean em up and lightly lube them 
with that copper brake lube.

Cheers
