especially if I need to brake hard it feels like there is a bump or that it sort of pushes back for a split second

92 prelude Si

 

Sounds like you're either feeling the ABS kick in, or you have a warped rotor.

prolly a warp rotor...do you feel the steering wheel vibrate to as u press the brakes?

 

do you notice the "bump" at high speeds, low speeds, or both? As the stock brake lines get old sometimes you can get vibrating feedback under high speed braking. I've heard stainless steel brake lines eliminate this. Check to make sure you don't have warped rotors first.

 

? Never heard of this happening. Hows that physically possible?

I would go with warped rotor as well.

So you only feel it in hard breaking? Do you feel it in the steering wheel at all?? That will help it isolate if its the back or front. Do you notice you veer to one side or another (or pull to one side or another) while breaking hard?

Jack your car up and spin each tire. See if it hits a point where the tire wants to slow down in its rotation. Listen too, you'll hear that spot where it hits the pad and the tire will slow down and probably make a rubbing noise when the pad meets the part of the rotor thats out of trueness

 

thx for the help. I has rained here a lot lately so warped rotors are a possibility but the steering wheel never vibrates or wobbles during braking even downhill. I does feel like the ABS but this is the same route I always take and I've never experienced this.

 

does it matter what speed you are at that you feel this ? Hard vs soft braking ?
Try and isolate the problem. Try when you driving to SLOWLY pull up the handbrake, if you feel it then you know its in the rear. Also when braking as usual does the feeling come through the wheel or feel like its coming from under your seat ?

Also is the ABS light on or kicking on when this happens ?

 

Only way you'll know for sure is if you jack your car up and play spin the tires, trust me. That will save us all from guessing
if you don't feel it in steering wheel than as lude 98sh mentioned you might be able to pull the ebrake and feel for it there. I would just assume though its a rear rotor that is untrue somewhere. This happens if let pads wear down and its metal on metal or from hard braking in general. Excessive heat can warp rotors eventually and age as well as just wear from hard braking

 

You mean rotors, right?

 

warped roters

 

we hav any lincoln tech grads hear

 

A warped rotor will cause a pulsing feel that changes with speed. The ABS is a much stronger "Kick". ABS in full operation also has more of a buzzing feel as the pulsing is *much* faster than that of a warped rotor. A loose abs sensor on the wheel can cause a single, but substantial kick in the pedal. One way to tell is to pull the huge fuse/breaker for for the ABS system. You will get a light, but ABS will not operate under any circumstances. No kick means that it is definitely an ABS issue.

 

If I'm right, the 92 Prelude did not come with ABS..cause I own a 1992 Prelude S and mine came with no ABS. But what it could be is and bare with me, that your pads have a dent in em.

I know that sounds stupid, but one time I was changing my pads when I noticed that a hole was right in the middle of both my pads. It looked like dents but IDK why it happened. I suggest you take a look in your pads cause you might be surprised...

 

Mine is 93 and has ABS.... But as for the hole in brake pads.... Many of them are manufactured this way as it is where they are riveted to the backing plate. The pads on some cars have different layers that have different composition or a soft metalic implant that causes them to squeak as they near end of life. If you get a grinding sound, then you are down to the rivets and they are leaving a nasty groove in the discs or drums.

If you have any real questions, the discs are pretty simple to replace and are relatively inexpensive. Discs are about $20-$50 each (average under $30) and a set of pads about the same. If you know what you are doing and don't have any problems, it takes 15-20 mins per wheel. If you don't have a clue but are mechanically inclined, do some reading and it will take 45 mins per wheel. On a 92, you may have a problem getting some of the screws loose.

If you don't have a clue, let a shop look at it, they can probably pinpoint the problem and fix it but you'll be out an estimated $200 to get both front wheels replaced.

 

well 92s came with abs...i have a 92 sr with abs (canadian, might be a diffrence, i'm not sure)...however i do not use abs

 

no dent

 

do you feel the bumb under your ***? if you did it would most likely be the rear. front you would feel it from the steering wheel.

 

If the roads are wet and your tires are balding out you could be hydroplaning which causes the ABS to kick in. I hate my 4th gens' ABS, I just decided to pull the fuses and the ABS light

 

It sounds like warped rotors for sure, if you want to tell if its the rear or the front get up to a good speed then slowly pull up on the e brake and if you feel the car shake then the rears are warped and then if you get back up to a good speed then push on the normal bake kinda firm and if the steering wheel shakes then you know its the fronts. if you cant resurface your own rotors just bring them down to a pep boys or even a brake shop and they can do it for cheep since you already have them off.

 

yes my apologies! Not rims, rotors rather.

 

You stupid redneck americans!! It's called a brake disc! Not a rotor! And if your getting feedback (that feels like a hard spot) through the brake pedal it's most definitely the abs system kicking in! (That we invented)

Merry ******* Christmas!!

lol, go pull your bonnet over your face and check the calender
