Parking break dosent work.

How hard or easy is it to fix them? I have a 91 300zx TT and it dosent stop the car from rolling one bit. Is it something any mechanic can fix or possibly me fix?

Thanks,

Josh

There should be an adjuster under the car. On my 85 its directly in the middle behin the cat and it takes a 8mm and a 10mm and a screw driver to adjust it. Fairly easy if you have ramps/jackstands/ or a lift.
