I would appreciate some help / collective knowledge with my parking brake.
The car: 2014 Mazda5. One year ago, the two OEM rear calipers were replaced because one side was leaking. The parking brake worked OK since then, but not at 100%. It was a bit lose on one tire (driver's side). It did not "grab" really well. In any case, it was working.
The problem: After using the parking brake for a couple of days (the car doesn't get a lot of use), it gets stuck, and won't easily release. After driving the car for 1 or 2 blocks, it would release, and then the car can be used normally.
So it was a little bit "grabby" in the beginning. It got worse over time, and now it gets stuck after using the parking brake for a short while. The worst happened a couple of days ago, I drove for about 10 blocks and it would not release, the calipers started to overheat, I had to pull over and wait a bit. Then, it released as before, and the car was back to normal.
The help I need: I cannot figure out how to clean and lubricate the mechanism. The calipers look clean from the outside, the spring look fine as far as I can tell, the cable has no cuts or visible rust, etc.
I guess I could replace the calipers again (but I don't want to spend a lot of money, changing calipers every year is not something I am looking forward to). I think the fix could be some lubrication. I just don't know where to start.
Anyone has any tips, or have experienced the same problem?
