Chevy Express/GMC Savana: Brakes

jcintcjcintc Posts: 3
I have a 2001 Chevy Express
The brake lights LT, center, RT will work fine until I turn the parking lights on & then when you apply the brakes the LT & RT go out & only the center will light up as a brake light. As soon as you release the brake pedal the center goes out & the LT & RT will light up as parking lights. If you or anybody has an answer please reply.

    Hi,

    I drive a 1997 GMC Savana 1 ton van. The two outside rear brake lights don't work, but the upper center bar brake light does. I've checked the fuses and the lamps and they are OK. Does anyone have any idea what could be causing this? Thanks in advance for your replies.
  • Hi
    I have an Express and I encontered the same question.
    It might be the same answer, I took a look into the lamp socket and found that there where no contacts for the braklight!!!
    This means I have two taillights on each side and just one brakelight on each side.

    I've got the same problem on my '99 Express. I haven't found the cause of the problem either, so I would also appreciate any information anybody can offer.

    I found the solution! The problem was that with the lights on, applying the brakes would cause the lower lamps to go out and only the center light would come on. With the lights off, I would only get the parking lights and the center light. The solution was to replace both of the lower lamp sockets.

    Can anyone tell me were the fuel pump is located on a 2000 chevy express van V6?, Thanks.
  • It's in the fuel tank
  • Hi! Thanks for your post. It looks like I am having the same problem with my 99 Express. Did you find out what was wrong with the lower sockets? I had my tail lights apart last night and could not figure out what was wrong. Then I did a search and found this forum. Did you notice any differences between the upper and lower sockets? Thanks!

    Thank you for posting this! It was the fix for my brake light problem as well. I found my replacement sockets at NAPA, part # LS6505, but I was a little shocked at the price for them, $30 each!! And they are the same exact part. I couldn't find a suitable replacement at any of the other auto parts stores, I'm sure the dealership has them, but they are probably even more expensive. I just hope they don't start doing they same thing as the old ones!

    My van is a 2001 3500 with the 5.7. It's got 121,000 on it right now. It is leaking coolant on the right side of the block. Looks like the head gasket, but it could be an intake gasket (hopefully).

    Has anyone had this problem?
  • I had this problem on both my99's. The Express was leaking externally, the Suburban had water in the oil. Both needed to have the intake gaskets replaced. Factory originals turned to dust-
  • I had this exact problem. Both lower tail light sock (R&L) had slight corrosion that caused the ground to no longer make contact. I replaced both sockets and it all works now. I replaced the sockets by buying a tail light wiring harness from a GM dealer and using the two sockets on the wiring harness, one for each side. I just clipped the wires, attached the new sockets, taped it all back up, and was done. To replace the complete wiring harness requires taking inside panels off, etc. Too much work. Just replacing the lower tail light sockets is all that was necessary and splicing them into the existin wiring harness worked fine. A wiring harnes cost around $70 from the dealer, so save yourself &70 and just buy one of them.

    It looks like the GMC vans must have a problem with water getting into the lower socket since there a number of people posting with the same problem.

    My 1999 gmc savana cargo van had the same brake light problem. What I did instead of splicing in new light sockets was release the contact terminal inside the socket itself, due this by using a pick type tool or small screw driver etc. and guide it down the terminal until it pushes and releases then i took some small stranded wire and wrapped it around the terminal and pushed it back into the socket. the wire stuffed in there puts more pressure and gives more contact area.
    Hope this reply can help out and i hope i'm being accurate enough as it has been two years since i did the repair. It is still working perfectly today.
    I notice these vans every day on the road with brake light problems. Don't know if it's moisture related or under rated/inferior materials

    I am experiencing braking problems. During slow driving conditions only, i.e. heavy traffic, excessive braking, the ABS and Emergency brake indicator light is coming on with an error beep./signal. This is causing brake failure for brief periods of time, bunny-hop, etc. and on two separate occasions, potential pedestrian and vehicle accidents. I have had the van at the dealer on two separate occasions and they cannot find anything wrong with the vehicle. Has anyone else experienced this? Please assist.

    Hi, vinnyb3,

    You can try asking in the Stop here! Let's talk about brakes discussion if you don't get an answer here. Hope you get this resolved soon :-)

  • I've got a 2001, 3500 Chev. Express and I decided to change the brake shoes on the rear dually axle. Question: Is the hub and drum make together on this big truck? I've been reading the shop manual, but I swear they are working on a different truck, perhaps the 1500 or 2500, where the hub and axle are clearly separate. I've already pulled the axle on one side, but it looks like I will have to take off the "axle nut retaining ring" and "adjusting nut" and "key" and finally the "wheel hub" WITH the big drum.
    This doesn't seem right--the bearings will be falling out just to change the rear brake shoes. I guess I could take a digital picture of the situation and ask at a brake shop, but I thought a would try this forum. Maybe there is a forum out there for mechanical questions. If someone knows of one let me know--I've got a lot more work to do on this truck.
  • After some investigation today, I can answer my own question: The dually hub and drum are one item. The axle nut must be taken off then the whole assembly comes off as a unit, bearings and all. I did have to buy a special socket for the axle nut though, #OTC 1929, for $38.
  • I have a 2000 Chevy Express 3500 Custom Van that the ABS Control Module or the ELECTRONIC BRAKE CONTROL MODULE or the ECBM depending on who I talk to is bad. I have had the codes pulled from two people and they both said it is bad. What goes wrong is it will not shut off when I turn off the vehicle. And over the course of the night, drains the battery. As a wheelchair bound former Marine, this is a pita..and since I am on a budget that a 1200.oo dealer repair bill blows clean out of the water I was looking for some advice.

    1st off does anyone know where it is located at?

    Maybe a Chevrolet Part number I can cross referance OEM versions

    And thoughts of obtaining one from a Salvage yard...it there a way to test one from a salvage yard with a meter if I talk my meter with me?

    Thx for any help.

    Respectfully,

    Auto Marine on Wheels :)
  • I have a 2001 Express also
    Having the same problem, confirmed myself that the socket are bad, the actual problem with the sockets are the way "they" attach or make contact with he ground wire to the socket. Its a pressure fit and my guess is dissimular metals. Add moisture to the picture and you get corrosion. I replaced both sockets to correct this problem. Using a NAPA replacement part.
    You would think this would call for a re-call.
  • (2003 express cargo 3/4ton, 34k miles, not heavy-duty use.) about 10mph the brake pedal mushes. mechanic diagnosis: replace front wheel bearing assy as the sensor is within that. 1)it seems this is premature for $500 repair. 2)could a pressure washer washing under the wheels have triggered it? 3)if not replaced, can brakes go out, or what are other bad can come of this? suggestions/thoughts?thanx in advance.
  • I have a 2001 Chevrolet Express 1500 LT van with 90,000 miles. I like the van, however, when I release the brakes, there is a "thud" in the rear brakes. Two different mechanics have looked at them, replaced the pads, adjusted them, but cannot eliminate this annoying noise. They tell me that there is nothing they can do to stop it. Are you all experiencing the same thing and have just gotten used to it? Or is there something that will fix the problem? What is the problem? Thanks for any advice that will help stop the problem (pun intended).

    I need to thank everyone for the answer to my chevy express van brake light problem. After I posted & no one replied I forgot about the post & the dealer wanted $480 to fix it. Since I only drove the van a couple of times a year I didn't have it fixed. This week I decided to tackle the problem, did a search on google & my original post came up. I had totally forgot it. But thanks to you guys the answer was here. Replace the 2 lower sockets, which I got @ NAPA for $39 & that solved the problem. Thanks again everyone.

    anyone know how to adjust the emergency brake on a 2005 chevrolet express cargo van
  • My brakes are acting super sensitive and will lock up if even moderate pressure is put on the pedal. I thought it was the front ones only as the van stays in a straight line, so I replaced the front pads, cleaned and greased the bushings. This only helped a slight amount. Anyone got any ideas?
  • You might need new rear wheel cylinders....i have 2 express vans...my 2000 has almost 400,000 miles...and my 02 has 295,000. GREAT VANS!!!
  • Hello there. First post. While we should all know that protecting (not over using the brakes) will help prevent warping and vibration, this post is different.

    '06 Express 3500 12 passenger van. Loaded up with people coming down a 9% grade (Jackson Hole, WY). I am a conscience driver and pay close attention to the vehicle, especially around extreme conditions. I was descending this grade with moderate speed and typical braking. The more I used the brakes, the more they became pulsating and alternating in the front (steering wheel shook back and forth ever more aggresively). I became very nervous as it became very severe and quickly downshifted the transmission and avoided the brakes as much as I could. I was certain that I had over used the brakes (even though I was paying attention and didn't think I had). I was certain I would have to have the rotors turned and brakes replaced in Jackson, WY. Silly think is once I was on level ground, the vibrations completely disappeared. With shaking that violent, there is no way that the brakes could have been that hot and the rotors that warped and not remain that way. Once rotors are warped, they are warped. But I tell you that I have not taken it in yet and they are as smooth as the day I purchased the van. It is like nothing ever happened. I do not understand why this could be.

    Any help? :confuse:
  • My 98 chevy cargo van has no brake lights. The regular tail lights work fine,but when I press the brake pedal,nothing.Now I have checked all the usual suspects like the bulbs,fuses and even brake light switch.I would appreciate any help with this problem.
  • I am having this same problem with a 1997 3500 express Van. The brakes are super sensitive after the van sits overnight. Slaming on the brakes at 10 miles per hour makes the problem go away for the day. I pulled rear drums and looked at front rotors. All looked good. No fluid leaks. Van only has 9,000 miles on it. No anti lock lights on the dash? Can any one help?

    I've had the same exact problem with my '05 2500 12 passenger van. Going down an extended grade, while using the brakes, I'll get a vibration that gets worse and worse. It seems like it must be heat related, because it doesn't do it in the winter and when it does do it in the spring, summer, and fall, it goes away as soon as I'm not using the brakes much.

    Have you found out the problem with yours?
  • I have a 1997, 3500 with 412+000 miles on it and the intake manifold gaskets were leaking. Replacing them did the trick but while all of that was apart I also had the fuel pressure regulator replaced also. It's alot easier to do it now than later since it is located inside the intake manifold. If you've noticed it takes a few more cranks for the engine to start that's usually the problem.
