Had a squeal coming from the rear when driving the other day, car felt fine although I did notice it seemed to take longer to change up (DSG), the squeal went away quite quickly. Drove it again yesterday about 8 miles and 2 miles in the squeal came back when I stopped I could smell the brakes my drivers side/offside rear was considerably hotter, didn't need to put my hand that close to feel the heat. I'm assuming this is a sticking caliper or bent sliders, now I have spare calipers at home only problem is I'm 500 miles from home working, luckily I don't need the car other than to drive home in November.
Is there a temporary fix that I could use to get me home and change them myself, only problem is I don't have any tools other than what is with the spare wheel with me, should have more really. Or am I better having the others sent up to me and getting a garage to change them?
