#673 of 1973 Here's my answer to your warped rotor problem.....
Jun 06, 2004 (7:41 pm)
My 2001 AWD Astro is my third. I drive a lot, 40,000 to 50,000 a year. My current Astro has gone 70,000 plus miles on front brake pads and rotors. My driving hasn't changed. I owe this to a savy Chevrolet service advisor telling me his "secret" when my OEM pads gave out along with warped rotors. This was at about 28,000 miles, by the way. He said not to use any other pads but carbon metalic after my rotors were turned. GM doesn't sell them but I went to a local NAPA and picked up a set. Wow, what a diffence it's made. I'm at about 110,000 on the "clock" now. I'll never use anything but carbon metalic on my Astros.

Thanks for the advice. Was there any special/oem rotor used or are they just the factory rotors? Also, I had thought of trying the ceramic pads. They are supposed to be the new thing!!!

No, factory rotors turned for the first time. And he said do not get ceramic unless you want to replace your rotors often. The big sercret(he said) to the carbon metalic is that they dissapate heat better than any of the others and it's heat that "kills" your rotors. Heck, mine are still smooth as butter after all those miles.

Great. Sounds like good advice. Thanks again.
#677 of 1973 Astro Highway Speed cough
Jun 08, 2004 (7:45 pm)
I bought my 96 Astro in 2002 with 100K miles on it, and it has been pretty good generally. I now have 135K miles and over Christmas I lost my fuel pump. When the pump was actually in the process of failing, I was cruising along the highway about 60mph, and the van started to cough, hesitate, then stopped dead all in about 5 minutes. I replaced the pump, my fuel strainer, and fuel filter.
Now, sometimes when I'm cruising at highway speed (more like 70-80 mph) it will cough a little bit. This has been going on for a few months and it is very unnerving. It hasn't died, it just coughs at highway speed. I checked the diagnostic trouble Codes and got a code for the camshaft position sensor. I replaced that, and it has helped; but still has not solved the problem.
A few things I suspect are: Fuel injectors, timing chain, and ignition coil. Presently, I am getting no Diagnostic Trouble Codes. I would appreciate any of your thoughts, experiences, etc. My brother suspects that I'm sporadically losing power to my ECM, but I've seen no code to this effect.
Too cheap to go to a dealer

I now have carbon metallic pads all the way around on my '03 Astro. We'll see if they are worth it. The stopping power is pretty good. I had the front rotors turned but I think I will have to replace them because they are thin and still a bit warped, not much though. I had to replace the rear rotors. I found it very interesting that the e-brake use a drum inside the rotor. Never seen that before.
#679 of 1973 Carbon Metalic Pads........
Jun 24, 2004 (5:46 am)
I just had my tires rotated at a Les Schwab store here in the area and they said that my front (carbon metalic) pads were down to 1/3 of their life. They thought I'd be an easy sell for new front brakes. I said given there is 1/3 still left, that means I can go another 40,000 miles before I need to think about replacing them. I invited them to take it for a spin and check out how smooth it still stops. No abnormal rotor wear. If it lurched or grabbed, it would be time to look at the pads and rotors but it isn't. One other nice benefit is that they don't make the wheels as dirty with the dust off the wearing pads. Mark me down as sold on carbon metalics for Astros anyway.

I have 95000 miles on my Astro. No problems, just regular maintenance. Can't beat that! And with three kids, we need the space. There is no other 'small' van that can beat the towing capacity! I just wish that GM would add On-Star, DVD, and curtain airbags to the 2005's. We would buy another one in a heartbeat. Seems that GM wants the Astro/Safari sales to decline. Baltimore Sun reported that in the latest UAW contract the plant was slated to close in summer of 2005. This model/plant also has the highest labor hours per vehicle in the GM lineup, so, guess that too was a determining factor, but, what can they expect with a 19 year old design. I just hope they update it or replace it with an equivalent, because I definetely will not hop on the Venture/Montana/Terraza/Relay bandwagon. According to http://www.gminsidenews.com/factsheet.htm, 2005 is the last year.

Well, its been a week since my last post and bragging about my van. On our way to Myrtle Beach last week when we noticed that, upon exiting the interstate coming to a slow stop, we started hearing a thump noise from the rear of the vehicle. We continued on as the noise only occurred when coming to a stop, and slower than 10mph. After arriving, we headed out one night in the traffic. We noticed the van started shuddering when accelerating in 2nd gear. It wasn't slipping, just shuddering, enough to shake the dash. No lights on dash, but, we were worried being 7 hours from home. When it was time to come home, we took it easy. It got us home. I took the van to a local 'trusted' mechanic and he couldn't figure it out. I then took it to the Chevy dealer. They too were stumped as to the cause. The weird thing is that it didn't do this until it was driven 10 miles, maybe enough to warm it up. The service manager, lead Chevy technician, and another technician drove it trying to determine the cause. They fist started with a full transmission flush and filter kit. No results. They then flushed the transfer case. No results, but, they did say it would take about 100 miles for the transfer case synthetic oil to get through all the parts (weird, I know). They also fixed the sticking gas pedal (carbon build up). So, $400 later, I drove it home. After a day or so the problem was gone. It has been doing fine for a week. Absolutely not shuddering or thumping. We had hoped it was solved. So, last night on the way home from taking the kids swimming, 3 miles away, it started again. There are still no check lights illuminated. The Chevy dealer said that if it happened again, the next thing would be to tear into the transmission or transfer case. He said a rebuilt GM tranny was $2500 and a rebuilt transfer case was $1500. So, we are going to live it it for a few more weeks to see 'what' happens or, if it gets worse. The van is in great shape, no rust, perfect paint, etc. I just hate to put that much money in a vehicle with 95k miles and 5 years old. The GM service manager said that he would personally trade it if it was his. So, this might be the end of our Astro days, only time will tell, short time....
#682 of 1973 About that '95 AWD Astro.........

Just a question or two because I had a similiar incident when mine was new. Does your van have a limited slip rear differential? Have you changed tires or rotated them front to back before the problems began?
In my situation, I put new tires on the van right after I picked it up from the dealer. The trouble was that one tire was not the same size as the other 3 and it happened to get mounted on the front. When it was rotated from the front to the back at 5,000 miles, it started trying to kick in the limited slip feature. The sensors were telling the limited slip to kick in because one tire was turning slower than the other. Chevy did all the things that they did to your van until one sharp eyed technician figured it out. Yeah, the tire dealer paid for it all.
Just thought I'd pass that along if it might be of help.
