ABS Sounds like its grinding

[Conman50]

A few times now I have had some low speed, short emergency stops. (Stop and Go that stopped really suddenly) And im pretty sure the ABS came on. But when it does, it kind of sounds like my front left wheel is grinding. Not sure if the other are doing it but that sounds the loudest.

I have had ABS active on my old Ford Focus and that felt more like a quick pulsing of the brake and you could hear a little tire skid. Im not sure if its the off road tires skidding?

Anyone else have any experience like this?

When I have used Trail Control (Low Speed Offroad CC) it uses the ABS, and it does have a noticeable grinding sound. Scared me first time I heard it, but found out it is normal.

Are your pads in good condition?

It's normal, plus you should be able to feel that pulsating under your foot that your braking with.


The momentary skid during abs is going to be the roadway surface condition, a spot of water/snow/ice, some sand or gravel , debris from prior crashes etc. After winter has been around a while and the roads are clear and dry, look at the radius of the left turning areas and some right turns. The plows and vehicles push that sand out of the way and there it stays , your go driving over it normally but if brake hard and hit that sand your going to have some skid or a sideways slide if make make a sudden movement like crash avoiding or hard fast turn.

as an Evo trainer I always introduced rookies to a sudden stop that would kick in the abs so that if and when it kicks in they don't freak out, then we taught them threshold braking. Threshold is right above the point where abs kicks in, it's maximum braking possible given the mixture of the condition of the braking system, the driver and the environmental conditions.

With threshold braking you don't wanna ride the brake, or 2 foot driving, you can find a comfy spot between the brake and accelerator and keep your heel planted so you only have to sort of wave your foot to the brake and only use the ball of your foot. That heel gives you a leveraged reference point to judge how hard to press the brake. If you have a front seat passenger and your parked as them to keep their arms pulled in and not touching the door and then you use your hand to push against the upper arm, when they don't resist u they will move a bit and you can't judge how hard your pushing, now have them stick there right arm against the door and not to budge and u push there left upper arm, that resistance you feel is how threshold braking feels and works. if you see a crash coming, and panic and raise your foot clear off the floor then as things come at you, you panic (without training) and smash the brake and crash anyway. you'd be surprised how much further your vehicle goes when you panic stop like that. Inches equal lives saved or lost.

Yes ABS can get you stopped but you can actually stop a car faster and in less distance using threshold braking. Now I'm only talking about one half to 2/3 of your car length but that's the difference between hitting a child, a bicyclist or T boning another car in front of you.

Abs is actually designed to allow you to keep rolling friction with the roadway so you can steer around an obstacle instead of locking the brakes (non abs) and sliding right into a collision
There's only 3 types of friction, rolling, sliding or stationary or static.

I worked more crashes than I can ever recall but I do remember that a vast majority of the car/driver who wanted to avoid a collision prior to abs coming out, had straight front skid marks for a bit and then you can see the tire turn in the now wider skid mark and the wheels still turned at impact. It's human nature to want to avoid a crash.

If you blow a fuse or now circuit breakers that power the abs system, by default your back to lockup and skid so I always taught my guys to just never get used to using abs just to be safe.

As for your knee, I had my right one done and I was allowed to drive after 2 weeks if no pain meds on board, but banging the side of that knee against that hard plastic console hurt like heck. Luckily I was only 10-15 min from my light duty office. I retired before I had my left knee done and it was MUCH easier driving, getting in was trickier.

I agree, it is normal. Sounds like it's grinding marbles.

A while back had an Olds Bravada. That thing was like a mountain goat on slippery winter roads. But, when the ABS kicked in it sounded like like the engine was falling out. They mounted the ABS valve bank on the metal inner fender and it was like a drum. Scared the heck out of you the first time you did it.
