Break Pedal kicking back toword's me.. Read This

[azmattaz06]

Ok so yesterday my brake pedal started going to the floor and also sometimes when im coming to a fast stop my pedal kick's back toword's me so i took it to Brake Master's (Bad Idea) and of course they will name everything that they possibly can so they tell me it need's a Master Cylinder,Abs/Anti skid realy.. All coming to a total of $845.44 so i decided to bleed the brake system after i did it started working better but it did that kicking thing again and then when i was in the drive thru all the sudden a cloud of smoke come's from under the hood smelling like break fluid and then it stop's.. So from what you gu's hear what do i need to fix? i can do the master cylinder if that's the problem but what in the world is a Abs/Anti skid relay? do i really need that? if you guy's think it's something else please feel free to let me know thank you -Matt

ABS it bumps up and down

huh??

Is this on an automatic? I wonder if your pressure switch is leaking. There is a recall for this and it might explain the smoke and loss of pressure.

That sounds about right. Fire, fire. Get that thing to the stealership and fast.

is the dealership going to fix it? and free?

Yes it's a recall. And if you don't take care of this quick. Your car could catch fire?

They'll fix it for free IF the problem you're having is the one that the vehicle was recalled for. I have no idea without actually seeing your car though. It sounds like it could be the same problem though.

This recall only applies to automatic SHO's by the way.

What about the Brake Pedal kicking back at me under hard braking? that can end up to be real bad if i don't figure it out anyone else have this problem or know what it is?

 

[frosho]

"Kicking back" as in pulsing? As in the ABS is doing it's job?

 

[azmattaz06]

No no i mean if im trying to slow down fast it damn near throws my foot off the pedal it pushes back towords me really hard to where i cant even push it down when it happening...

 

[frosho]

That sounds pretty f'd up. Maybe you do need a MC. Or maybe a problem with the return spring... IDK, I'm no expert on that part of the brake system.

I hope someone else can help you out better, and soon. That sounds dangerous.

 

[azmattaz06]

yeah well im trying not to race or anything because in normal driving it's never happened.. it's hard not to racew these damn little honda's but i gotta quit for a bit.. for anyone that understand's what's going on with my car please send some info my way thank you

Well it sounds like you have a problem in your ABS unit. I'll have to look in the pub for it's exact operation, but sounds like there is a check valve that isn't working and your feeling the caliper line pressure backing up through the MC when your ABS solenoids and motor actuate.

Certainly need to get that fixed, but know you can still stop if you have to. Just pretend it never had power to begin with and push the pedal to the pavement.

+1 on bad ABS. A bad MC will not, i repeat not, force the pedal back up at you with that amount of force. A bad ABS unit, however, will. It is very possible that the hose going from the MC to the ABS unit ruptured or fell off (the brake fluid line). Check that first. It's about 1/2" wide. Failing that, check the ABS unit very thoroughly for signs of leakage/ruptures. You may have to spring for a new ABS unit. Which is neither cheap nor easy to replace. Sorry ...

It's fairly common for grease from failed CV boots to be flung into the sensor ring...distorting the ABS signal and making the ABS unpredictable.

For $800+ it's worth looking at the sensors to make sure they are clean and grease free.

None of that explains the smoke, of course...a leak of that magnitude SHOULD be fairly easy to ID.

Wasn't that report hilarious?


You gotta wonder - I bet they even got the cardboard they're using from WalMart . . . .

. . . . for free !


Anyway, back to the problem. Matt, do the ABS and BRAKE idiot lights properly during test-out when you start the car? Are the ABS or BRAKE idiot lights coming on when you're getting the pedal feedback?

 

[CPUNeck]

Oh yea Matt, one more thing. Try starting the car with your foot on the brake, when the ABS cycles through its' self test do you feel a single pulse? If the cause of your problems is your ABS unit, the effect should be more violent than the normal pulse.

i had a 94 atx that did the same thing...id like to know what does this as well seemed random to my car i could just be doing 60 and hit the brake pedal and it would kick back hard so i justs had to put my foot through the floor board occasionally

 

[93rev2sev]

Look at your sensor rings!
