There is your answer right there. The calipers are adjusted with hand brake usage, If it seems to be getting tight and/or feeling tighter, the self-adjusting mechanisms should be working. Just make sure it will hold the car on an incline.
Let the board know how it goes in a few weeks.
The answer was not there: fixed, not fixed, or maybe?
This slack in the hand brake was really making me nervous since I installed PowerStop brake last year and that I already experienced the back left wheel jammed in January. Yesterday after a 30 minutes drive, I touched the rotors and the driver side was definitely a bit warmer than the passenger side, leaving me worried.
Again the emergency brake spring was full of sand and manually testing revealed that the plate would not retract completely, enough to prevent to turn the rotor by hand (using the studs). The dealer said 10 days ago that they were fine. These guys owe me 60 bucks. If you want my opinion, this system is/was not appropriate for sanded roads up North.
I took lots of brake cleaner but didn't threw the empty can like Ray’s Rainman repairs… Even with that the plate would not go back all the way.
By looking at it very closely, I noticed that there is a o-ring seal between the plate and the spring assembly.
So, I took some AT-205 that is supposed to rejuvenate rubber and is the best stuff in the world as per Scotty Kilmer (I think he must be putting some in his coffee!). Then after many cycles the plate now comes back 99 percent.
I put the wheel back on with two nuts and brought the jack to let that soak and will retest tomorrow morning.
I’m wondering if the o-ring should not be replaced. Maybe the AT-205 will fix this for a long time.
One question:should I lubricate it if it works fine? Forget synthetic dielectric grease, it will catch all the sand again. What lubricant should I use? Is there the same mechanism on the passenger side? Didn’t look but obviously it’s working.
