Assuming this vehicles brake linings are ok and not worn out, it sounds like you have an abs rotor fault. The abs is working while your are braking because it cant read the road speed correctly. So you are feeling the abs motor working.

Chevy equinox 2005. Every time I step in breaks it makes a pulsing grinding sound. Think it might be anti lock, but not sure.

Could be, but more likely is that you are metal-to-metal on the brake pads and are grinding into the rotor, warping it. If that is the case replacement of the pads and rotors, at a minimum is required. You should have the brakes checked immediately.

Grinding noise when step on the break.


The grinding noise could be indicative that the brake pads have worn off and the metal backing is grinding with the brake disc. This is further supported by the emergency brake light indicator which would illuminate (even when emergency/park brake is not engaged) when the brake fluid is low or the pads are too thin or gone (as in your probable case). Even though the grinding sound is only on the left side, it would be to your advantage to repalce both sides. Additionally, pls have the disc themselves checked as they may need re-surfacing.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Escalade Grinding sound coming from left front when stopping

Most likely cause would be disc brake pads grinding against brake rotor.

Not all the time 50% the brakes have a grinding pulsing sensation they don't stop normal when this happens ant the brake pedal is very stiff. the rotors are not the problem nor the brake pads the rear...

I would like to learn something here. I understand what you are saying.

Question I have is--grinding,pulsing,don't stop normal and pedal very stiff.

I assume you personally removed the wheels and are familiar with your rotors etc.

I know your looking for answers, not being asked a question,but even ABS issues,power booster and other things excluded, you don't get grinding sounds and pulsing if there are no issues.

Just asking,so I can help as we go here.

Grinding sound when I break and after I break. It

You are correct. The pad has worn down to the steel backing pad, and now you will have to replace your brake rotor as well.

ABS light & trak off light keep coming on. Grinding noise & vibration can be felt on brake peddle. Brakes have been checked. Wheel bearing was replaced on drivers side. Sometimes making a pulsing...

It sounds like "False Antilock Mode" to me. Your Antilock Brake Control Module "thinks" that you have a wheel locking up. This is probably caused by a bad wheel sensor. You need to scan the module to find out which one.

04 cavalier makes grinding noise in front end turn the wheel to the right grinding gets worse turn the wheel to the left grinding stops. it sounds worse at 40mph and above. what would cause this?

3 things to check:
Worn disc brake pads, grinding against the rotor.
Wheel bearing
cv joint.
You posted grinding gets worse turning to the right, the problem is the driver side wheel, but it would be best to have both wheeles checked.

Brake Noise

Does the car have an anti-lock braking system? Could be that the wheel is sensing a brake lock when there is none and the pulsing is coming from the ABS motor activating, and the grinding/moaning sound is the ABS motor running. If you have never checked or used your ABS system, take your car out to a big, vacant lot or on a street where it is safe and you can get the street wet. Get going about 50 or so and, (after securing all the loose stuff in your car and trunk,) lock the brakes up. You will feel a pulsation in the brake pedal and hear a wierd, moaning noise. That is all perfectly normal. The pulsing is the ABS motor and related parts applying and releasing the brakes repeatedly at a high interval. This is what keeps the brakes from completely locking up and gives you the ability to steer and control the vehicle while jamming the brakes on fully. If your car doesn't have ABS, the caliper may be sticking in and the noise and vibration are from the pad being loose between the caliper and the rotor. Take the wheel off and watch the pads while you have someone else push the pedal. Have them push it VERY SLIGHTLY at first and see if it locks the rotor from turning by hand. If so, it is probably working correctly. If not, it should lock up before they feel much resistance in the brake pedal. Still, if not, the rotor is probably sticking because the dirt/grunge ring on the caliper piston probably isn't letting the caliper travel out far enough since the rotor was turned and the caliper has to make up for the extra space. This is probably not the issue since we are only talking about a few thousands of an inch, but still...
It is hard to diagnose using someone else's ears, but you might go by a brake shop and ask them to listen to it and see what it sounds like to them. If a brake shop can't answer your question, find another brake shop!

Grinding sound when step on break

Sounds like your brake pads/shoes need replaced. When the brake linings wear out, you have metal to metal when you step on your brake pedal. You may have to replace rotors/drums due to severe scarring.
