Check the park brake system for its ability to generate sufficient cable tension:
The wire strand of the parking brake cables is coated with a plastic material which slides against nylon seals inside the conduit end fittings. This plastic coating is for corrosion protection and reduced parking brake effort.IMPORTANT: Plastic coated parking brake cables do not need periodic lubrication.Handling of these cables during servicing of the parking brake system requires a little extra care. Damage to the plastic coating will reduce corrosion protection. If the damaged area passes through the seal, increased parking brake effort could result. Do NOT allow the coating to come into contact with sharp-edged tools or with sharp surfaces of the vehicle underbody.
this is the cable assembly. I wouldnt mess with the drum.
