- Most common is aftermarket pad, dimensions most are slightly smaller.
- Worn pad retaining shim/s these can loose their tension effect over time, allowing the pads to move.
- Worn retaining pins and/or a combination of some or all of these.
So I checked the EBC and SBS pads, need to find out what the OEM pads dimensions are to compare -
EBC FS380 (W - 69) SBS 634 (69.2)
EBC FS380 (H - 50.4) SBS 634 (51.03)
EBC FS380 (T - 8.7) SBS 634 (8.8 )
The tension plates dont have a lip on the sides of the celiper to sit on, so the whole pads+clip assembly just rotates/pivots on the pins. As for the tension they are spot on, so in conclusion nothing wrong with the clips and the both pins were perfect, no wear on them at all.
So I have put some of the EBC anti-squeel back clip/shims on the pads, but dont think these will do anything for the rattle, but worth a try. I have also carefull put a bead of some of the expensive silicon greese that Gaz66 sent me on the sids of the pads. Is these both do nothing then the next step is to replace the calipers.
And on the subject of replacement calipers @Gnasher, which year/s XJR/FJ calipers will be a direct bolt on as I am not buying another set of FZ1 calipers due to the inherant wear issue.
