I've come to the conclusion that my parking brake is quite weak. On a slight incline the recommended 8-10 clicks (according to the sources I have found online and this site) doesn't provide enough bite on the rear discs and the car will roll. I've got into the habit of taking the parking brake to all 18 clicks (fully extended) when parking.
Armed with nothing but online resources and a Sunday afternoon I decided to try and take care of this one myself.
I started by reading
this and
this thread showing how to remove the center console and adjust the parking brake, respectively.
If you look at the second thread, a DIY on adjusting the parking brake step 3 is defined as
Loosen the parking brake adjusting nut (A). A digram is listed.
Below I have linked to an image of my 2007 Civic Si Sedan and what I believed was the parking brake adjusting nut
at first glance.
Upon closer inspection it appears as if this nut and corresponding bolt do not control the parking tension. For one, the nut isn't adjustable. Only the bolt as the nut is held in place by it's surroundings. Wording, I know, but odd nonetheless. Picture two below is a side view.
It appears as if that nut and bolt assembly only fasten the plate and teeth that the parking brake ride on to a more sturdy brace. It appears to do nothing for the tension of the parking brake itself. Despite this, I followed the directions. No changes were observed.
The bolt that appears to be used to tighten the parking brake is listed in picture 3 below.
I traced two cables running down between the seats (one to each rear brake, can be seen in picture 1) back to the single cable they merge into (via a small device). This single cable meanders into the shift assembly and I cannot tell where it goes, but it appears to make its way toward the bolt and nut in picture 3.
Just wondering if anyone can second my musings. Service manual will be ordered as soon as they are back in stock. Until then, well...
Thanks in advance.
