[diesel_mercedes] Parking brake light stays on

 

Hey folks,
I have been driving my car every day. Since I put in the new battery, it
has been a LOT better at starting in the cold even without the heater.
But that is not what this is about. In stages I have been rebuilding the
front suspension. That last thing I did was to replace the lower ball
joints. I ran into a problem with the right caliper when I did that
side. The inner piston would not go in. First, I cleaned up the pad
perches, which were binding the pads. Completely removing them, I could
not get the inner piston to budge. I finally limbered it up by
retracting the outer one, clamping it with a C-clamp, then applying the
brake a few times to make the inner one start to come out. On the second
try, the piston freed and I was able to push it in with no further issue.
So now, I have four fully functioning brake calipers. That one must have
just been going along for the ride.
But now I have a new problem. The parking brake light stays on
sometimes. So far I have removed the rear calipers and checked the
adjustment of the rear shoes. They were a little snug, so I adjusted the
star wheel in just a tad. I then made an adjustment under the car at the
arm just behind the transmission (the adjuster bolt turned with no
issues, don't you just love working on southern cars!). The parking
brake pedal moves just the right distance and the PB grabs nice
(actually always did, but I didn't like the way the shoes were dragging.
The light actually was staying on after I worked on the front brakes and
before I adjusted the rears.
Yanking upward on the PB pedal does no good. I checked the master
cylinder and it is full.
The PD switch looks to be in a horrible place, way up on top of the
mechanism.
Has anyone had luck working on these?
