Parking brake stuck on

Mon Apr 18, 2016 1:56 pm

Five months ago, we purchased our 2012 Nissan Leaf. We love it.

A few days ago, my wife used the parking brake and afterward it would not disengage. I looked up the issue and followed the manual procedure for releasing the parking brake via using the emergency tool in the trunk hole method.

However, the rear drum brakes continue to be engaged. The car is not driveable. I've rechecked my work and can find no fault with mine.

It appears the rear drum brakes are stuck on.

How is this possible?

The Leaf did experience a rear end collision and body work a few months ago.

Could this be an instance of poor auto work?

Problems with the parking brake seem common place.

Is there a recall or similar?


Thanks!

How long was it parked with the brake set?
Could it just be stuck due to rust?

It was parked less than a day.

Was it raining when you parked it, or very high humidity? I agree, kind of sounds like the pads stuck to the rotor, have you try accelerating very hard, or possibly in reverse? I had an issue on a vehicle where the pads stuck to the rotors(after parking a few days after driving in the rain) and initially it refused to move, after accelerating fairly hard I heard a crack as the pads broke lose from the rotor, was fine after that.
Note if accelerating fairly hard while the car is stationary be very careful as when the pads do finally break lose the car may lunge.

The car moves fine in reverse. Moving forward is possible, but it required a lot more effort than normal and the brakes seem engaged and dragging.

There was no rain or high humidity.

I know my regular disc brakes stick a little bit after I wash the car, but not the parking brake, and not like you're describing.

I'm out of ideas. If you like working on your car, try to pull that drum off & see what's going on. Otherwise, take it to a garage and get it fixed. It's probably a simple problem. Good luck!

If thats the case then do NOT drive the car for more than a few feet, for example don't drive it to a shop, have it towed. Driving in that state would cause the rotors to overheat causing much more problems than whatever is sticking. Not sure what to think when you said everything is fine in reverse.....BTW aren't all Leaf brakes pad and rotors? I know my '12SL is...as Garsh said, sounds like to time to take it in, that or if your mechanical and have the time, l try taking it apart yourself and see if you see anything that looks odd.

Yes, but the parking brake is actually a separate little drum brake on the back wheels. See here for some pictures & adjustments that can be made.

If the parking brake is engaged, would the car be able to move backwards easily?

If no, what could be the problem with just moving forward?

I guess if one end of the pad were wedged against the drum , it would allow rolling in one direction, but would bind in the other. But that's a guess.
