Hi all,Iv'e got four leaking brake calipers on my 74 I have organised to get stainless sleeved but I want to try the "o"ring style seal and piston kit, does any one know where to get them from in OZ ,I can get them from Ebay US but not sure about quality,Oh and I have emailed Vette Brakes &suspension you speak of twice and no reply so I gave up on them.Most others want to much to ship small items,Has anyone tried these o ring seals.
