my husband has gone to change the rear discs and pads today on my astra mk4 sri 02 plate, problem is when going to return the piston the marks differ from the haynes manual. As you can see in the pics the piston has a faint white lined mark, not a cut out as shown in the manual. Also the caliper does not have a raised mark?
please could someone tell me the marking points for this piston/caliper?
thankyou very much[/IMG][/IMG]
