Well, I know I need to take The Truck in to get the brakes done. As is
my usual M.O., I'd like to get some opinions from here as to what work
might need to be done. There's more going on than just the sticky
caliper, but the other stuff was so intermittent and seemingly that I
wasn't really bothered until now. Now that I'm paying very close
attention to my brakes during commutes, I'm starting to put two and two
together, to form a better picture.
Again, 2001 Dodge Dakota SLT 4x4, 4.7l v8 engine. ABS Brakes. No codes
from the computer.
Back in July, I had the brake pads and rotors replaced. The rotors were
rusty and worn, and had previously been replaced less than 5 years ago.
Truck had just under 70k miles, and this was the first time the pads
have been replaced. Due to some of the intermittent issues, I asked
them to look closely at the entire braking system, but they didn't find
anything else wrong.
Most of the intermittent stuff has been happening before the
replacement. No new symptoms happened after it. I brake gently, and
use the engine to slow down when it's appropriate. I never stab the
brakes unless I need to. They feel normal and stop well.
1. Twice on rather rainy days in the spring, I guess the calipers stuck
after I released the emergency brake when leaving for work in the
morning. They released within about 20 feet, suddenly and with a clunk,
then gave no further problems. This has not happened again.
2. Periodically, and with no relationship with the weather, the brakes
will make a clunk sound when I'm braking, usually just before I come to
a stop (maybe 5-10mph). Braking feels normal, but there's this very
distinct clunk. Usually this might happen a time or two during a drive,
then stop. It doesn't seem to affect the play of the brake pedal itself
(ie, it doesn't stop or sink more during the clunk)
3. I sometimes feel a "gravelly" sensation in my gas pedal. I never
connected that to my brakes, but maybe that's the calipers?
4. There's a very faint feeling of "drift to the left" right at the end
of braking. Actually, this may have started (or just gotten more
noticeable), after the last brake work.
5. Often after I brake, and mostly when the weather is warm, the brake
pedal might sink very slightly a few seconds after I've come to a stop.
Master Cylinder I think was checked ages ago and found fine, I
remember being told this might just be a slight flexing of the frame.
6. I checked all 4 wheels after my commute yesterday (about 20 miles) -
had the gravelly feel and the just-before-stop clunk. The front wheels
felt only slightly warm, back wheels were cool.
7. And of course, the Event I mentioned in my previous post -
caliper(s?) sticking hard after slowing for a light, including inability
to accelerate properly (engine roaring), and burnt brake smell.
Released when I stopped to figure out What The Heck Happened.
8. Before the brake work, when starting the truck the ABS light would
stay on an extra couple of seconds, ding, then go off. That was one of
the things the shop checked & couldn't find anything. Since the work,
it's only done that a couple of times.
I'm aware some of these might be unrelated, but I'm a troubleshooter by
trade (tech support) and know that sometimes things that seem unrelated
are the key to solving an issue...
Any advice is welcome. Also, I do trust my current mechanic, but for
this would it be better to take the truck to someplace that specializes
