On advice from my garage I had the rear discs and pads replaced on my MR2 (2004 with 85,000 miles) at the end of January. I took care with the discs to wear them in. I have driven around 600/700 miles since the discs were changed. This has been on motorways, A road, country backroads and some town driving. However, since the two discs were changed they have both been running constantly hot - over a distance of 12 miles and moderate braking you can burn the skin off your fingers, and hear the tink, tink, tink of cooling brake discs after the car has stopped. The discs heat up even if I don't us
