Have you already pulled the calipers and checked for a leak there?
#78 of 116 ABS system on 97 Blazer
May 22, 2008 (11:58 am)
At times my ABS kicks in when it's not needed, no slipping and low speed. Brought it to a mechanic who quoted $1090 to replace the Wheel Speed Sensor and EBCM. Not sure this car is even worth $1k anymore. I've disconnected the ABS system and it's not happening anymore. Is it all right to drive with the ABS disconnected? Or is there a less expensive solution?

The price you were quoted is fair depending on what parts the mechanic uses. The OEM GM hub bearings w/ABS rings has a MSRP of $1084 a pair with a jobber price of $564 per pair. However, the you can get excellent quality aftermarket hub bearings w/ABS rings for $270 a pair from places like AutoZone. If you have been using metallic brake pads, the ABS rings may be clogged with metal dust. The ABS reluctor is a magnetic sensor. The ABS rings on the front and rear may just need a thorough cleaning.
Mechanics make nearly as much money off the parts as they do their labor. I would get another opinion about replacing the EBCM (electronic brake control module) in fact they can be rebuilt for a third of what a new one would cost. The jobber price for a GM EBCM is $516 with a MSRP of $992. Jobber price is what the mechanic would have to pay for the part at a Chevrolet or GM dealership parts department. Most so called "discount" aftermarket parts stores sell to the public at jobber price. In other words, you can purchase the parts at AutoZone just as cheap as the mechanic. When the mechanic buys at jobber price, he adds at least 20% to that price for his parts profit margin. Some mechanics add more than that! Unfortunately, hardly any mechanics will let you buy and furnish your own parts. They gotcha coming and going.
The labor cost to replace the front hub bearings w/ABS rings is about $200 . The EBCM is about the same. Labor $400 + $785 for parts = $1185. I considered replacing the hub bearings on my 1991 Blazer 4x4 SUV whe I do a brake pad and rotor replacment in the next few days. I want to replace the hub bearing wABS ring and rotors just because they are OEM equipment that is 18 years old and I plan on playing with the vehicle for a long time. I have no ABS codes yet. I will do the labor myself so all I will be paying is for the parts.
If you disable the ABS, you will have standard power brakes. I have owned five high performance Pontiacs and Chevrolets in the 1960s that were equipped with drum brakes and two of them did not even have power brakes! My 1963 Pontiac Catalina had 370 HP, weighed 3900 lbs., with standard drum brakes without power assist! It was sometimes quite an adventure coming to a high speed stop!
#81 of 116 Brakes making whoosing sound

My 97 chevy blazer brakes are making a long whoosing sound when I apply the brakes. They are working fine otherwise. My mechanic thinks it may be the brake booster. What are the symptoms of the booster going out? Should there be other signs?

Could be a vacuum leak, yes. Other signs would be a very hard brake pedal and a sense of decreasing brake grip.You'd feel like you are pushing harder but getting less braking.
#83 of 116 1986 S10 Blazer Braking Equilizer Valve
Jun 06, 2008 (1:50 pm)
The valve next to the master cylinder (I believe it is referred to as the "Equilizer Valve" - where the brake lines come out of) has leaked for quite some time, but now the wheels lock-up at times when the brake is applied. I have been trying to get a replacement, however, since the vehicle is 22 years old, the part is no longer manufactured by Chevrolet. I went to a junk yard and bought a replacement twice with both leaking after installation - what luck! I am at wits end with the situation and am looking for alternative sources at this point.
Does anyone know of a rebuild kit I can purchase? Or a place that still manufactures the part? Thanks.
#84 of 116 00 Blazer rear brakes
Jun 29, 2008 (6:16 pm)
I had the pads,rotors , and brake hoses replaced and the right rear brake still heats up a lot and smells.
Any other thoughts on how to fix it.

Change the caliper. They cost about $40 for a rebuilt, and are available lots of places. These calipers do not "reset" well, and the piston tends to bind and stick, causing the pad to drag (sometimes REALLY drag) and overheat.
Had the same problem on my '99 model.

I always associate calipers and pads with disc brakes. I guess the "wheel cylinder" gizmo with the piston in it amounts to about the same thing (but they act on "brake shoes"). I'm assuming that the Blazer has rear drums?
One of my rear drums imploded last month and I wound up having to get a wheel kit (bearings etc.) in addition to a brake job. Not cheap.
