A while ago i had the sticking rear offside caliper issue, I replaced the caliper and all has been well for 4 or so months. I had new tyres put on today and noticed a creaking/ knocking sound coming from the rear when braking and coming to a stop, can only hear it when im doing say under 15 mph and braking. Only seems to have started after the car has been jacked up and tyres changed though which is a bit odd. Also one minute the handbrake will be nice and tight and take about 3 clicks and the next minute it will go right up so im guessing its something to do with the caliper/handbrake mechanism, also notice an odd mettalic rattling sound associated with this problem too. Anyone have any ideas?
