Firmer brakes with the ABS disabled?

[SHOGUN88]

I unplugged my ABS module because it was acting up at low speeds after I broke one of the sensor's when I was replacing my rear suspension. The new sensor is on it's way. I have come to notice that my brake pedal feels firmer and more effective, is there any truth to this or is my mind just messing with me?

 

[LOUDSHO92]

No truth as the ABS system is passive. It's like deleting A/C to save power.

So why does the abs kick in when its not needed anyways? The ac delete doesnt give more hp? I thought it would because it doesnt have to spin the pulley?

So do you like, know how cars work?

 

[sho4life]

I would say that abs kicks on because a sensor is acting up and the ac bypass is because the ac doesnt work anymore. Why would i go on a forum if i knew everything. Oh because i want to buy and sell stuff.

omg, your so confusing with the way you word things. I guess you were trying to say that your car has abs issues?

 

[sho4life]

my abs works great on my sho but the explorer it kicks in the annoying grinding rrr noise when you come to a complete stop even its a dry road.

Check for dirt, grease (half shaft boot ripped?), debris caked in or around one of the trigger wheels.

ABS kicking in while coming to a stop is almost always a malfunctioning ring. Usually it's a crack; teeth could also be missing or it could just have crap built up in it.

The AC pulley does not use any engine power when the AC isn't on, unless the compressor has malfunctioned.

So I have a growling noise coming from the front left tire. I thought maybe it was the bearing but that was replaced not too long ago. I noticed that after the car was stopped it smelled like something was burning or sticking and was very hot. I checked the pads and the inner one was done to the metal .Could this cause the caliper to come out too far resulting in the brake sticking and causing the abs to kick in prematurely and the noise.. etc..

 

[hawkeye18]

No, but seized caliper slider pins will absolutely cause that. A worn inner pad is a sure guarantee of stuck sliders.

Unless the sensor ring gets clogged with brake dust (which is possible), messed up pads generally won't affect the ABS system.

4WD explorers have the sensor internal in the hub bearing assembly, a 2wd old body style explorer has a tone ring on the back side of the rotor. If you have ABS problems on a 4wd, you will probably be replacing hub assemblies.

Well....sorta.

On a single-piston setup (or even the dual-piston on the LGT), the inner pad will virtually ALWAYS wear faster than the outer pad, even with good sliders.

Overly excessive wear on the inner can be a stuck slider. Just had that a few wees ago on the LGT. Inner and outer were both far nastier than on the side with the good sliders, and died before their time.

I suppose I should've clarified further. An inner pad worn to the backing plate and an outer pad with plenty of life left on it is almost always slider pins.

 

[notbange]

It seems (in my experience) it's usually the other way around. A stuck slider keeps the outer pad applied, and as long as the caliper piston still moves freely, the inner pad can still release.

I had a problem with ABS coming to a stop or driving into a driveway and stopping and my wheels where not perfectly straight. One time almost didn't stop. Had to disconnect my ABS system.

 

[sho4life]

The inner was completly gone and the outer was still at 50%. i replaced pads and still has the smoking and burnt smell after 3 minutes at 40 mph. Im going to buy a new caliper bracket and hopefully it fixes it. What happens when A CALIPER fails?

 

[Art5]

sometimes it is not the caliper but hose that is bad and caliper doesn't come back. If I were you, I would look into changine caliper hoses too, preferably to stainless steel braided. It is kinda of expensive, but will improve your rakes too.

 

[hawkeye18]

Replacement of the bracket isn't necessarily required; you can pull the slider pins out of the bracket and buy a new slider pin set for quite a bit cheaper than a new bracket.

Once you have the pins out, you need to sand them down to remove the corrosion on them, then fill them with grease and at the very least put new boots on them (which can also be purchased separately).

Cracked boots is the most common cause of losing grease, which is what causes the pins to seize.

The pins may be very difficult to remove.

I decided to buy news pins, boots and bracket because one was so rusted stuck it was a bother. new one only cost $35 at rock auto. I did the other side today and im surprised those pins werent stuck also, no grease left at all.. I start fixing one thing and now have to buy more parts because things keep breaking or i find something that is about to break, thanks guys
