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.
Should you pull handbrake all the way up?
You should apply it fully, otherwise it won’t be properly on and won’t hold the car! When applying it, be sure to press the button in rather than letting it click over the ratchet, as the latter will increase the wear on the ratchet which could eventually lead to failure.
What happens if you pull the handbrake too hard?
When you pull your lever too hard, it can cause your brakes to become stuck against the wall of your wheel drums. To release a stuck brake you can do several things. If it is safe to do so, you can try rocking the vehicle back and forth or manually getting under the vehicle to pull the cables.
How hard should you pull handbrake?
If your handbrake is working properly, you shouldn’t need to pull so much that you struggle when you are releasing it.

Which way do you turn a brake adjuster?
