Hello, Do the rear brake callipers not last long on the C4?. I only ask because handrake was not working and mechanic found out that the caliipers had seized. Car has done 85000 miles and is 8 years old. Cost of callipers was £98 each. I only ask because I never came across the brake callipers needing replacement ( I have owned several Citroens,Vauxhalls,Fiat in the past). Many Thanks
