Hand brake 'pops'

Hey everyone,

Just joined the forum and am thrilled that such a great community exists! I'm learning a lot and have searched for an answer to my question to no avail. So, here goes . . . I bought a new Wrangler JKU and it's a dream come true! Naturally, I baby her like crazy, but did off road the first day so I'm not afraid to get dirty. Still, I want her to last FOREVER so I am a little concerned that when I pull up hard on the brake handle (e.g. to keep from rolling on an incline) I get a 'popping' sound about half way up. It is not the ratchet sound of which I get five good 'clicks'. It sounds like a cable or gear popping into position because it's not aligned. Any ideas what this could be?

Mine does the same. Curious as to what it could be.

Flood the "clock spring" with oil and it will stop the clunk. Look down the lever past the bristle slot and you will see where to put it. Channel the oil down a screw driver or through a soda straw. Might have to operate the lever a few dozen times to distribute the oil. It'll work.

You've discovered one of the banes of the JK. My E brake doesn't work if there's ANY incline, so I carry wheel chocks. I can literally push it when the brake is up tight.
(I've had it serviced multiple times, and I just put new shoes in it).

I have the same problem with my 2012. It doesnít do it all the time but enough to annoy me. When I get around to it Iíll give it the oil treatment like psouza1943 suggests.

I will be watching this thread to see how oil affects the e-brake clutch spring. It depends on friction to grab the cable drum. I would think oil will cause it to have less friction.

I washed mine down with brake cleaner to increase its grabbing power.

Damm almost got whiplash reading your post, thatís a 180 difference from the oil fix.

Since cleaning it out using brake cleaner worked also, then I think Iíll try that first. Iíd hate to add oil only to find out it made it worse and then have to spend 30 mins or so cleaning out the oil to make it dry again.

Better yet maybe Iíll let the dealer give it a shot first since itís still under warranty.

Crap, I wish I never read this thread to begin with; it doesnít take much to get my head spinning these days.

Fantastic! It worked perfectly, thanks to the tip from Phil (psouza1943). I used a small piece of cardboard bent in a 'U' shape to hold back the bristles and a flashlight to see the area illustrated in the picture posted by ronjenx. Thanks to ronjenx, also! I was cautious and used a little bit of WD-40 because it had a directional spray nozzle. So I did not 'flood' the are, but added a small squirt worked the handle up and down and squirted a touch more. The 'pop' went away after just a few movements. I don't notice any difference in the friction but if I do, I will post again with an update. You guys are the best!

Are you guys getting the "pop" constantly or just intermittently? I only seem to get it when I really crank up the brake handle quickly, I have only heard it 3 or 4 times so I tallied it under the "Its a Wrangler, what do you expect?" category...

Mine is happing like you are experiencing but more frequently. Also itís not a "Its a Wrangler, what do you expect?" categoryĒ. My í08 never had that problem and it had way more miles than this 2012 does.
