Been having some metallic scrapey noises from my Polo (mk3 '94) recently. Noticable when driving at slower speeds even when the brakes weren't applied.
So I had a look at the front calipers yesterday, undid them, removed pads (plenty still on 'em) sprayed the lot with brake cleaner and re-asssembled. Seems to have solved the noise problem for now, but I noticed on assemble that the nsf wheel does not turn freely, and I suspect the the piston or other caliper part may be sticking, which may have caused the pads to contact the disc whilst driving.
So I'm considering refurbing the front brakes.
Not au fait with the workings of brakes and calipers, I've read elsewhere about sliders. Would my calipers have these? and am I right in thinking that they are what the 2 allen head bolts round the back, screw into?
I was under the impression that the back of the caliper body is securely fixed in place and doesn't move. ?
So if I were to take apart, clean and refurb the calipers, what tools/lube do I need? Copperslip is on the shopping list already as there was hardly any on the backs of the pads. What sort of grease would I need for the other bits?
