Driving on community street 25mph heard loud explosion . car barely ran but got 1 block to an audi dealer . they inspected car and told me parking brake exploded and gave me lots of metal pieces to show the volvo mechanic . called volvo of north america but they denied ever hearing about this type of problem and volvo dealer wants to charge me $1700 to replace parking brakes . talking to other volvo owners they have had same problem and volvo refuses to issue a recall . is there any way your agency can encourage volvo to do a recall ? thanks *tr
