If your parking brake isn't working correctly, the problem likely lies within the system itself and requires professional attention. Possible causes include:
* Worn-out brake shoes: The brake shoes in the rear drums are worn down, requiring replacement.
* Damaged or stretched cables: While there's no external adjustment, internal components of the cable mechanism might be damaged.
* Malfunctioning automatic adjuster: The automatic adjuster might be jammed or broken, preventing proper adjustment.
* Low brake fluid: Although less likely to directly affect the parking brake, low fluid can affect overall braking performance.
Instead of attempting DIY adjustments, which could be damaging and ineffective, take your Cavalier to a qualified mechanic or auto repair shop. They have the tools and expertise to diagnose and fix the issue properly. They'll be able to determine the cause of the problem and replace worn parts or repair the automatic adjuster as needed.
