Having problems with your 1998 Chevrolet Blazer ?

ABS BRakes ABS system activates when you slow down & turn to the right while pressing on the brake pedal , such as pulling into my driveway to park , it does not activate when you turn to the left & do the same thing , both front wheel sensors have been checked & they are OK I have a '98 Chevrolet bazer. the ABS come on between 5-8 MPH regardless if the brake pedal is pressed. I've checked the front wheel snsors and they both read about 950 ohms.

Answers :

I recommend checking the gaps against specification (sorry I don't know what the spec is, check with a local dealer) between the tone wheel and the sensors, and making sure that the wheel bearings do not have excess play. The bearing play can mean that the gap changes when turning a corner, either too much gap or not enough, and the sensor gives a different output from the other 3 wheels which the abs computer thinks is wheel slip and the abs is activated. This may only apply to the front sensors, your vehicle will likely just have one sensor in the rear, mounted on the diff head, but if it has 4 sensors then check out the axle endfloat in the rear also.

Hope this helps,
Mark.
