Parking brake on my 1995 850 turbo is not holding. Have adjusted rear parking brake shoes and internal hand brake adjustment without success. Could the brake cables be bad? Dealer says cable replacement is about $400 plus another $200 if parking brake shoes need replaced. Is there an easy way to tell what might be wrong (dealer diagnosis is about $130) and is there a procedure somewhere I could see that tells how to change cables etc. Thanks.
