Need some help with brake problems on my 2004 chevy 1500 silverado. Having problems with peddle going to the floor board with no brakes unless I pump the peddle. No ABS light comes on and I don't here the unit come on either. Has happened at least 12 times since new 12/20/03. Chevy service says that brakes are normal and they find nothing wrong every time I have been into dealer. My problem is that I pull a 21 ft. boat with surge brakes on the trailer that only work when the towing vehicles brakes work. I have 19,000 miles on it and have been lucky so far. I have been towing the boat with my 78 chevy wagon with good brakes. The problem seems to occur when temp. is below 50 degrees outside.The problem is very intermittant. Any serviceman or owner with answer to this problem would greatly be appreciated. I am thinking something wrong with master cylinder like bad "O" rings. Chevy customer service pretty much told me, "IF IT AIN'T BROKE DON'T FIX IT. Pretty good for a $33.000 vehicle. Won't be buying any more GM products. Thanks for any come backs.

too often. About the speedometer, dealer ordered one, national backorder, finally got it after nearly 45 days (fun driving with no speedo) and they replaced it.
#662 of 1497 My '99 5.7 has a security system glitch..

Hope you guys can help here. My truck randomly refuses to start and the security light on the dash flashes. Called Chevy roadside, said it will always reset if given time. That was comforting. Does it a lot. If I had a dime for every time,I could finance my next tank of gas. Hate it at the pumps or when I need to get to work!
Note that when the blessed light burns steady on the dash, the truck will start but the system is disabled, also comforting. I live in the sticks and don't mind the disable thing, but this refusing to start isn't working well for me.(It's a long way to work from here) Apparently the system, when enabled, cuts the fuel to the engine. Any way I can just keep the *#$^ thing in the "disable mode" ? I tried to pull the fuse, since it seems to work with other problems,temporarily. No dice. Engine won't even click!
Some of these solutions above are amazing. Can anyone fascinate me on this one?

This just started for me this weekend, twice..brake pedal goes to the floor, truck seems to keep rolling, I have to pump the pedal to get it to stop. 2002 silverado with 35k on it. Warm day, about 78 degrees. Had been driving around awhile.

Try the "Maitenanace & Repair" board with these problems (copy and paste the question from here to that board) Put the question out to user named "Opatience" he seems to be pretty good with helping out on problems. He does not visit this board though.
Copy and paste his response once you get it to this board.

I had my speedo replaced too free of charge. When I had mine done in march the dealer told me of many people with the same problem and it was taking months to get the parts. Maybee Chevy should send out a recall.

Sep 19, 2005 (3:46 pm)
I have a 96 Chevy p/u with Vortec 8. Over past 3 months, sometimes I go out the truck will start and sometimes it just keeps turning but won't crank. A year ago, the check engine lite came on and they told me it was the crank shaft position sensor, put a new one in but we never could get the check engine lite to go out. Over the past 3 months, we have put a new fuel pump on the truck, a new ignition module, another crank shaft position sensor and today again it has decided not to crank. Has anybody had this problem or have any suggestions. I can't afford to keep taking it to the repair shop, the mechanic finally said he was experimenting by swapping out parts until the truck cranked. I have talked to several other automotive repair shops and most of them don't want to touch the truck.

Does this always happen with the same key and did you have this key cut? The security system takes a reading from the key and this could be giving some problems. When I put in my remote start I had to bye and install a device that copies the key signature to start it without a key.
#668 of 1497 Battery Display Goes on/off on in a C/K 1500
Sep 18, 2005 (1:21 pm)
I drive a 2001 Silverado 4.8 size of engine. With 26Km on the engine.Recently while driving the "battery display" will stay on for a few seconds then go off. The cycle repeats every 4-7 seconds but never stays constantly on. A check with my FLUKE VOM while the engine is operating shows the alternator reads 14.25 volts at the battery terminals with minor changes of +.2 volts.
The OEM battery "green" eye indicator is green with 12.4Vdc open curcuit and raises to 14.26 vdc when the truck engine is operating.The meter shows a good DC with next to nothing AC from the alternator P lead to the batterey
Any ideas on how to fix.

The dealer says it is the EBCM (electronic break control module) which I believe it most likely is, but they also said it was leaking coolant, and it is not. To have the dealer fix it would cost about $1K. I have been looking into doing it myself. There are people who rebuild the modules, and from what I understand, you do not have to open the hydraulics to do it. It is in a tight place on top of the ABS pump. The low coolant light was due to slightly low fluid level (my fault). The fuel gage will have to wait.
