My parking brake lamp remains dimly lit even after the ignition key is removed. I have a 03 Sierra 1500 ext cab. Any ideas??

I am pretty sure I know where your problem lies, I had identical symptoms. Dealer replaced wheel speed sensors, still had the problem.
Dealer replaced master cylinder, still had the problem.
Two days after the master cylinder replacement, the truck told me what the problem was, it began to growl in the front end. Wheel bearing was shot....way shot. Prior to that day there was no noise whatsoever, but when I picked the front end off the ground, the left front wheel tipped a couple degrees, at least.
So, all along the wheel bearing was progressively worsening, as a result the wheel speed sensor was being lied to. It is simply a prox. switch, and sometimes it couldn't see what it was looking for, due to play in the bearings.
I changed the bearing assembly myself, mainly because it was a Sunday morning, and on Monday forced the dealer to refund my money for the previous uneeded repairs.
That was three months ago, and brakes have been fine since.
By the way, the wheel bearing assembly, $150.00 or so, comes with a new wheel speed sensor.
Hope all this makes sense, and helps.
Good Luck!

How many by mooseye

Just how many times does a specific part have to fail prematurely in order to be a problem that the manufacturer should fix?
 I mean, this is only one site of many and there are 18 pages of the same or similar problems with brakes on chevy trucks.
 I live in Tennessee, but my used truck came from NY. I could not tell the rust to just stop even though it is not in a northern state any longer.
 I have had three brake line failures in less than a year on my '99 silverado. I have an '88 truck with no brake problems at all and the lines are not rusted.
 
And one more thing.
  I think all Chevy truck/suv/whatever owners should go out right now and crawl under their vehicle and take a look at the brake lines. You may be unpleasantly surprised.
 The bad thing about this problem is that the brakes may work fine until need in an emergency situation where hard braking is required. Then the weak rusted lines will not hold the added pressure and the line will fail leaving you with minimal braking or none at all.

2005 Silverado 1500 Crew Cab Braking Issue by gandalf77577

Yesterday, my 2005 silverado started making this weird roaring sound when braking. It ONLY happens when I am breaking and doesnt cause the car to jolt or shake. It sounds just like a plain is flying over, its a low rumble or roar that could be grinding too. Oddly enough, I cannot hear it outside the vehicle with the window rolled down and i can only hear it from inside. It only happens when i brake really slowly and am breaking at a slow speed. Quick breaking or slow breaking at high speeds doesn't cause the sound. It only happens when driving slowly and braking slowly. Its has 72,000 miles on it, has always been serviced well, and it was just inspected and it passed just 3 days ago (tx). Anyone have any ideas?

I climb under my 2003 2500 HD silverado, Durimax Diesel that I bought new to change the oil and look at eveywhere there was a clip on the brake line it was ready to rust through. So I go to the local Auto Parts store to get some brake line. The fittings on my truck are 14mm nuts with either 10mm or 12 mm threads on the nuts, and the line is 10 thousands bigger than 1/4 inch line. Advanced Auto, and NAPA as well as all the other auto part stores have only american standard threads on their brake line pieces. I will get metric inverted nuts then they don't have them and can't get them????Ok, I will get metric! CAN'T they dont have any metric lines,or nuts on 1/4 inch line? You've got to be kidding me!Nor, can they get it??? They have no Inverted fittings on 1/4 inch metric either??? My line is not bubble its inverted??? OK I go to the Chevy Dealer and order the parts--- I can't all their computers and books tell me their is American line and nuts on my truck. The parts guy looks at my line and says thats metric, but nothing listed in computer is metric for 2003,2005,2002 and he can't get it either. So only option I have is to cut off line and re-use old nuts on 1/4 inch line and hope the flange tool compensates for the 10 thousands line size difference and what if I strip one I'm in a world of hurt. Is there anyone else that has had this problem? I can't be the only one in America with this problem and what did you do?

Hey Fideuce,
 
I have not heard of this issue, we have 4 GMC pickups in the family and not had this issue, we have had our brakes, and brake line rusting, but not the metric/american issue. You may review some of these threads... #125 of 178Re: Rusted Brake lines, 2003 GMC 50K miles [barnowl3] by ttaupier1, ..........in the : Forums/Pickups/Chevrolet Silverado & GMC Sierra/Chevy Silverado and GMC Sierra Brake Problems
 
There are several links and different guys that needed to find the solutions to similar problems (rusty lines). To tell you the truth, I am very surprised this is the first time, we have seen or heard of this, knowing the vehicles are mostly manufactured in a Metric based countrys, and serviced in the USA, ...almost sounds like there was a daily supply issue and someone at the factory came-up with a short time fix... Yikes...
 
keep us posted..
