Hi Folks,
I have recently completed (I say completed but there is always something left that could be worked on) a restoration on my SV - anyway I have a little over 1000 miles on the car and have developed a "clicking" from the drivers side hub - it is rhythmic increasing with speed and more pronounced on sweeping right turns, if you touch the brakes even lightly it goes away. I checked the bearings (which are new) and they seem set OK so I am convinced that it is the inner pad "bouncing" up and down on the pins. I have confirmed that the brakes are not binding (even used a thermometer to check the temp of both discs after a good run) and can recreate the sound simply be rotating the hub by hand which is how I see the pad moving a little up and down making a clink as it settles back against the pin. The Pads I have fitted are from a local store and were ordered under the Datsun 160Z part number something I have done before without issue. What I notice and can not remember if this is true for all the pads I have used in the past is that the two outer holes in the pads body, through which the retaining pins pass, are elongated and not simply round which is what allows the pad that little bit of up and down movement.
I did not replace the discs as they looked serviceable and did not see replacements available anyway so I am wandering if the outer or inner lip of the disc is just catching the pad in one area as it catches that spot and then releases it again as it passes - before I start doing anything too radical I did wander if anyone else has any comment!
thanks
Gary
