Done 1000 miles in the car since its 'B' service and MOT in January at MB main dealer, last run was to the South coast and then up to Norfolk before returning to Northants last Monday. Took the car out Sunday and it felt strange at the back so pulled over to check everything was Ok and notice the drivers side rear wheel and brake was very hot. let it cool down and returned home. Took it to MB Northants this morning and they said it has a seized rear brake caliper. They have stated it will need an O/S caliper, a pair of discs and a set of brake pads. Has anyone else had rear caliper seize suddenly. I would expect something if it was left since October but it is a daily driver.
