Question about 1998 Chevrolet Blazer

1 Answer

Abs (1998 Chevy blazer 4WD) When breaking the pedal hardens and unable to break. While breaking I hear an electricit whining. I think it's ABS I have read possibly fixes but confused about what exactly is wrong. (power booster, wheel speed sensor, EBCM, wheel bearing sensor, master cylinder, abs modulator, or just sticking calipers.) problem doesn't happen all the time. It does happen when on a slope or when driving at a low speed. Abs light is on.

SOURCE: Spongy brake pedal even after ABS bleed and base brake bleed.

Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.

SOURCE: 95 silverado 4WD ABS light

The best way is to get a scan tool and monitor the speed sensors while driving and see which one is dropping out.One other thing is when you replaced the sensors,did you clean the surface area real good?You have to remove all the rust from the surface where the sensor seats.Because sensor has to have the correct gap.When rust builds up the gap gets to big and will cause the light to come on and the brake pedal to pulsate.The other thing is the ring inside the hub bearing will have a hair line crack in it and this will cause the same result.This means you have to replace the hub bearing.Hope this helps.Good luck.

try bleeding your ABS block first, if that doesn not work could need a master or proportioning vavle. Some scan tools are capable of bleeding the ABS system on some vehicles, and some you have to bleed manually.

2000 Chevy K3500 No Breaks. Bled breaks, not losing fluid, ABS and break lights on. Hydraulic booster system. makes hissing sound when breaks applied???


I think I would get the body computer scanned for trouble codes and find out why the ABS warning light is on first.
The hissing noise usually means the booster is leaking vac but if the booster was faulty the brake pedal would be hard to push.

ABS light on, flashing 4wd 2005 Mazda Tribute


Even though your anit-lock brake system light comes on, dosen't mean your brakes will not work. All the ABS does, when applying the breaks, it compensates breaking power like pulsating your pads off and on the rotor in which without ABS your doing the same thing manually by pressing n releasing the brake pedal. And usually half the time it's a sensor that goes out and can be checked at your local autozone or auto parts store where they can plug into your car and will display a code that pertains to your ABS problem. Hope this helps.

Hi my name is chris i have a 2001 chevy blazer 4x4 for so reason it keeps putting itself into 4x4 when i stop at a light or stop sign and won''t let me put it back into 2 wheel drive ?


There's been a lot of problems with the 4wd systems on the blazers of that vintage. The only sure way to track down the cause is to have the system scanned. Some of the most commom causes are: the switch in the dash, - the control module, - the transfer case . There are other issues if it has auto 4wd as the ABS system is tied into that system to activate it when the sensors sense wheel slippage. If your blazer has the auto 4wd funtion and has a ABS light on, it could be in the ABS system.
IF you could get it back into 2wd, you could pull the fuse to the 4wd to dis-able untill you have a chance to have it scanned.

What does it mean when my 1998 chevrolet blazer's antilock breaks engage when not needed when im driving slow i can hear them engage and have to push breaks for them to stop. or when i am stoping with...


GM has had an issue with rust building up on the on the abs sensor mounting surface located on the bearing. This rust build up causes an increase in the air gap between the sensor and the exciter ring. What can be done is to remove those abs sensors on the front wheels and clean the surfaces of the abs sensors be sure to cover the holes that the sensors go in to avoid particulates from getting inside the hub bearing once the area is cleaned you can apply a small amount of grease on the mounting surface then reinstall the sensors. Several vehicles with this issue have been corrected in this manner.

Blazers in park = rattling noise ..... Blazers in drive = whining sound & while driving on interstate (ranging 35mph-65mph) I can feel it hesitate when I press on gas almost as if it can't (but it doe)...


have you had the catalytic converter checked. When they break apart they will make a rattle ling noise. eventually the broken pieces will plug the exhaust and cause a lack of power feeling. When the exhaust is cold hit the bottom of the catalytic converter with your hand. If it rattles it is bad and needs to be replaced.

1996 chevy blazer 4wd break petal goes all the way to the floor breaks r good new master cylinder blead all braks 10 times any sugesstins? help!!!


I know there is ABS in that vehicle, you might still have air in the ABS unit, you will need to get a manual that shows you the correct procedure to bleed the brakes. Master installed u need to start the bleed on the bench, then move to the ABS unit then to the individual calipers and/or wheel cylinders if equipped. I think there is a certain way to do it to avoid incorrect bleeding.

But i have also seen bad master cylinders brand new in the box.

Good Luck.
