Pontiac Repair: emergency brake, gm service, proper tension

Question
2.2 l eng-'99 sunfire----    how do you adjust the cable? brakes done and adjusted as tight as one dares--emergency brake doesn't hold

Answer
Hi
Here is EXACT GM service Information procedure

Park Brake Cable Service/Adjustment
Notice: Parking brake adjustment is not necessary. This is a self adjusting system and damage may result from attempting to adjust or modify this system in any way. It may be necessary to adjust the rear brakes to obtain the proper tension in the system.
Fully apply and release the hand brake 4-6 times in order to self adjust.
The parking brake is self adjusting.

Hope this helps
