Chevy Blazer GMC Jimmy Maintenance and Repair

    I have a Kelsey hayes 310 on my 1995 chevy Cheyenne c3500hd truck but can't get the rear brakes to bleed how do I get the abs motor to engage and self bleed? I tried to use the dirt road method and it didn't work although I hear the motor engage and run for a few seconds each time I hit the brakes. Do you have any ideas? The garage wants $150.00 to bleed the brakes and I am not working....otherwise I would gladly pay that.

    I have a 1991 S10 Blazer with the EBC4 ABS and the only way to bleed the brakes is to use a GM Tech 1 scan tool and cycle the modulator as you bleed it.Then bleed the brakes in the normal manner.

    I have never found a auto repair shop that still had a GM Tech 1 scan tool. I am sure repair shops use the "slam the brakes on a gravel road" method to bleed the ABS modulator. Did you ever wonder why repair shops will not let you watch them work on your car?

    The ABS brakes the later models is much improved over the first EBC4 4WAL brake system. Repair shops should have the correct tools to bleed those brakes.

    Any help on these issues is greatly appreciated! My wife drives it now and I'd like to take care of these issues before we give it to my daughter to drive. We replaced the transmission at 110k miles. It has 160k now.

    1.) lights behind the left-most 4 preset radio station buttons are out

    2.) Every time I get in or out of the car, there is a loud creaking / squeaking noise. I was told these are bushings most likely. Are those hard to replace or lubricate?

    3.) Right front door doesn't close correctly all the time. It looks like the door has a tendency to sag / droop below it's intended track / path, so it sometimes closes all the way, sometimes not. Of course, my daughter and wife's solutions for it are to slam the door harder.

    4.) 3 of the 4 speakers are blown. Anyone else have this problem? Daughter hates loud music, as does my wife. They seemed to go out when we had the intermittent turn signal buzzing problem a few years ago.

    5.) Discoloration of the front wheels...brake dust? How to fix that? or can it be fixed?

    6.) Any suggestions on a good replacement stereo and speakers? What type speakers does it require?

    Again, thanks much for the input!

    In order my suggestions are

    1. If your radio has the speed controlled volume (which I really like) I would find a junkyard replacement, could be cassette or cd.

    2. Squeaking could be a lot of things. I would check the ball joints first, since they are pretty prone to wearing. A front end alignment at a locally owned shop (not a chain) would rule them in or out. Some can be lubed and some cannot, ask the alignment shop.

    3. The right front door is probably a worn hinge or bushings. Open the door and look at the hinge at the front (upper and lower). If you caught it in time it will just need bushings. The parts are just a few dollars, but installing can be tricky the first time you do it. A body shop will probably charge an hour labor to do it for you. If the bushings are worn through into the hinge, then it needs new hinges, bigger issue. If the hinges on yours are bolt on, it's a doable fix, if they are welded on, it's a major deal.

    4. The front speakers are really small, like 2 inches. The door speakers are bigger, can get aftermarket replacements, but I would go with junkyard parts from the same as the radio above.

    5. If it is brake dust on the front wheels, a white-wall tire cleaner like bleach-whyte and a scrub brush will clean them. If not, hard to say.

    recognize that this is probably a $1500 vehicle, so I wouldn't spend a lot on fixing these items.
