Question about 1993 Chevrolet S-10 Blazer

2 Answers

Brakes go out at speeds above 60 mph

I have a 93 chevy blazer s-10. I bought it as a restore project to tinker with. The ABS light has been on since I bought it. After I replaced all the brakes driving around town was fine but I discovered once I got on interstate and get up around 60 mph it feels like only one wheel is grabing and it sounds like grinding metal. The first time it did this I almost wrecked because it caused the vehicle to shift around. Once I get back under 60, the brakes seem to go back to normal and brake fine and normal. So, I have just been using this vehicle for little trips around town.

I took it to a brake place and they recommended a brake pump and brake module. Does this sound like what could possibly be the problem? Also, when they say brake pump and module are they referring to the brake booster and ABS module?

You may need the hydraulic control for the anti-lock, but it is more likely you need a wheel speed sensor, if the anti-lock module looses the wheel sensor signal all types of strange brake concerns occur, check all the wheel sensors and the trigger wheels, make sure they are not clogged with dirt or have broken trigger wheel teeth or damaged wheel sensor wiring

I would say that the module they are refering to is the module that allows even distribution of fluid pressure to all the brakes evenly. The exact name of the module escapes me at this moment, but that is what I would recommend in order to fix this problem. As for the pump, this the master cylinder. It also has a check valve that could be a factor in the uneven pressure at higher speeds, but I would start with the distribution module.

Abs light on everytime i stop it dies what would cause that on a 95 blazer

The abs light problem is more than likely a faulty speed sensor as for engine cutting off sounds like a low fuel pressure problem.Check the fuel pressure it should be 60-66 psi with the key on engine off.Also check the fuel pressure regulator for proper operation these regulators are known for causing this problem.

Abs light comes on when driving above 60 mph but brakes work fine in my volvo v40

Brakes always work but ABS may be not functioning.
This is probably to be repaired by experienced repair shop.
Brakes are too serious to make experiments by yourself.

My 1997 Chevy Blazer ABS light comes on and then shuts off but does it regularly. Also it makes a noise on the front brakes when using them. What could be the problem?

One of the wheel speed sensors is going bad probably. If the brake is shuddering when pressed like when the ABS kicks in then the sensor is bad.

60% of the time when applying the brakes the abs system kicks in and makes the weird noise and hinders braking

A shop will need to check the wheel speed sensors, maybe one is reading "0" and the ABS thinks the wheel is locking up, when its not.

ABS under 10 mph goes off...feels like we won't stop!

Like the other person mentioned, if you have a faulty sensor or bad connection, that would trigger the light. That may also be triggering your ABS to kick in when it doesn't need to. On each wheel, there will be a sensor with some wires coming out of it located on the inside of the axle just behind the rotor. You'd have to test each sensor to determine if one or all of them are faulty.

Anti lock brakes activation

if abs activates when it should not,,, it means abs module senses one or more wheel sensores under 3 mph and the other sensores are above 3 mph. .the cause of this is usualy a bad wheel speed sensor or excessive air gap between the sensor and ringwheel. you need an abs data scanner to hook up and go for a test drive to find out which sensor is the culprit.

ABS brake system comes on everytime I stop - no codes set

Test your wheel speed sensors. You can do it with a DVOM or a hand held lab scope. With a DVOM you want 2.8VAC while spinning the wheel and with a lab scope you want a good sine wave pattern.

Brakes go out at speeds over 60 mph

Glen; you have a bad wheel bearing is what it sounds like to me so here's what you do.Jack the front of the rig up grab a wheel fromthe top and bottom and try to wiggle it.if it does not move try the other one buy the sounds of it you should find some movement in one of them.If not got too a garage and just have them scan the ABS system and that should tell you which sensor is not working and that wheel should be the bad bearing since the ABS sensor is built right into the bearing.s10's are known for bearings going bad.

My abs light and trac off light are both on

Def the wheel bearings/hub/speed sensor. I just bought a new wheel bearing comes with the hub and speed sensor as one. Runs about 80-100 dollars though but abs/traction light went off and stays off now.
