Volvo Repair: parking brake stuck, parking brake cable, emergency brakes

Question
Phil,
   Maybe you can help me out.  I've got a '90 Volvo 240.  I pulled the parking brake all the way on, and now I can't get the lever to release.  Consequently the rear wheels are locked up tight.  I want to tow it from the rear on a tow dolly.  But I can't budge it because I can't return the parking brake lever to the "released" position. The cable is not froze up.  It had been working fine.  But rather, the lever having been pulled to the furthest on position, it now won't release.  Can you make a suggestion on how I can either release the parking brake or otherwise release the rear wheels .  With the brake on, would that mean that the hydraulic rear brakes are engaged?  If so, is there some way I can release the rear brakes? Bleed the fluid maybe?  Might there be an easy way to release the tension on the parking brake cable(s), or the hydraulic fluid to release the rear brakes?  Any suggestions at all?  Thank you for your anticipated input.-------Jack  

Answer
You have pulled the parking brake past it's limit on the racheting gear. The cover needs to be removed to access the assembly. You'll have to return the gear back onto the rachect assembly. This happened because the parking brake adjustment was too loose.

The emergency brakes energize the parking brake shoes within the rear brake rotors which is a separate circuit from the regular brakes. Bleeding the system will do nothing to release the parking brakes.
