How do I know if my handbrake needs adjusting?
So how do you know if your handbrake needs adjustment? The average number of handbrake clicks from down to up should be between 5 and 8. Anything above 8 could suggest that your handbrake needs to be made tighter and likewise, less than 5 clicks means it's too tight and can cause your rear brakes to drag.
Can you tighten up a handbrake?
The adjustment bolt will be located on the parking brake lever. This bolt tightens the cable leading to the rear brakes. Tighten the bolt by a few turns and then check the parking brake cable. Check the brake by pulling the lever up and feel for tightness.
