Could some kind person confirm these are ATE callipers, you can see in first pic they are knock out pins (no "R" clip) and is that a vauge "Ate" I can see? before I order from Brickwerks want to make sure I get the right ones. they are binding, tried easing them but no joy, pretty solid! dont fancy refurbing them (if you can get reputable parts) must be original I would think (1984) so guessing the piston and rubbers are shot! tried moving the brake pipe unions after a good spray and soak over the last few days so possibly end up with more hassle than its worth, replace the lot, dont want them failing. not particularly cheap, but if you can't stop could cost a life!
Thank you in advance
