One of your sensors is out on your ABS system. What will work until you want to fix it is to pull the fuses for the abs( the one from under the hood) and theres one you can pull from the fuse box on the left side on the dashboard. you will not have abs braking but the petal will not get hard and unless you drive in snow its not a ploblem driving without ABS

SOURCE: ABS BRakes

Check the brake light switch at the pedal. However an overheated/melted bulb base means arcing to me. So, BOTH sockets are probably slightly corroded & rusted. You fix that by scraping the terminals inside the socket with a pocket knife or screwdriver. Clean with alcohol or contact cleaner. If the new bulb isn't tight, and can be moved back and forth by hand, bend the contacts inward slightly, but don't snap them, they are spring steel. I was wondering when somebody would ask this question. I fix them at least to once a month - not the same car, but all GM's, and when fixed, they're good. Use logic if centre safety/brake light works.

The remote start sounds normal. There are many different types and they are quirky.

You should scan for codes with an OBD II scanner. If the problem was in the brake light connections or is fixed at the pedal, erase codes. It could be, by coincidence, and in no relation whatsoever to this problem, that a front wheel bearing sensor has gone - they do that, and require a new hub assembly.

SOURCE: Bad Brakes

I would be looking at the ABS valve. one way to test the booster is to start the vehicle while you ae depressing the brake pedal, you should feel the brake pedal drop a little bit, this is a sign that the boostr is working properely. you may want to check to see if there is any air in your system as well.
hope that this helps.

SOURCE: 94 s10 chevy 2wd brake pedal fades to floor before stoping

Might check around the big black round muffin shaped chamber adjacent to the master cylinder for a loose vacuum hose or crack therin; the hissing sound seems likely to be the air rushing in as you loose the vacuum that supplies the power to assist your braking effort (power brakes)---as this goes, so goes your peddle until it reaches the actual piston pushing the brake fluid (which should be firm like with non-power brakes).
...maybe have an assistant push on the peddle while you listen with a piece of hose or a stethescope to find the leak (or I suppose the power unit diaphragm could be shot/leaking--hence replacement), but since you said after bumpy road etc, one could hope for a simple dislodged vacuum hose or fixable crack.

Rav4 intermittant hard pedal


If the ABS system were the problem, the ABS warning light should come on.
So I would say the problem is with the vac booster. The booster is between the pedal and the master cylinder. It uses vac to boost the pressure applied to the master cylinder by your foot.
You may have to leave the vehicle with a mechanic to drive until the problem occurs.

What is abs how it function


ABS is anti-lock braking system. It is a range of four sensors which monitor the braking capability when you apply the brakes. If you are harsh and stamp on the brake pedal there is a risk of the wheels locking up and sliding (screeching from the tires).

The ABS sensors modulate the brake caliper pistons andapply and let go the brakes very quickly. This stops the tires from skidding and you will feel a pulse through the brake pedal as the hydraulic system is forced to release the pedal slightly for a fraction of a second.

As ABS stops your car from skidding it allows you to turn the steering when you are braking hard. This is good news for avoiding accidents. If you lock the wheels on a non ABS car, you continue in the direction of the wheels - unless you release the brakes and reapply quickly (same method as ABS) this is called cadence braking but when involved with a potential accident the last thing on people's minds is to release the brake pedal. Having only owned older cars, cadence braking is one method I've learned, especially from driving in the snow.

I hope this helps you and please vote for me :)

I changed the rear brakes on my Jetta tdi and now the brake pedal goes all the way to the floor. It does stop eventually and the parking brakes work. But it stops poorly


you probably have air in the line after brakes are done refill resevoir with brake fluid then the caliper has a little screw for bleeding brakes you must pump brakes 2-3 times leave your foot down until you have someone else open the screw on the caliper to release air or sometimes brake fluid close screw and repeat until the petal gets hard again do it to both rear brakes see if this works..

Abs brakes chirping noise, when pedal depressed,


worn out brake pads and slightly warped rotors. Most brake pads have small steel tabs that touch the rotor at a 90 degree angle when it is time for replacement. if you keep driving on the worn pads, it will stop chirping but that just means the tabs (also called wear indicators) have broken off and repair is about to get very pricey.

Bearings bad, grinding when I hit the breaks,petal pulsating


when your bearings start going bad two things happen first the ring gear that the abs reads the wheel speed moves to where it doesnt get a reading so that would probly be the abs light and second the flexing in the rotor will tend to colapse the brake piston leaving extra gap between the piston and the brake pad you might be able to confirm this by doing small short pumps and see if the pedal improves and it stops better i suggest replacing the bearings in pairs if you continue to drive the vehicle you run the chance of ruining the calipers hope this helps

Antilock brakes not funtioning properly on "hard" stops


Yes, I never did like ABS brakes because of this. What you have experienced is the ABS system working as it is designed to do. I know, it doesn't seem like you should still be moving after slamming on the brakes, but here is how it works;
When you apply a fast and hard pedal and the ground beneath you is wet the wheels stop at different times. There are sprockets mounted to the rear of the rotors, with magnetic sensors that monitor the wheel info. for all four wheels mounted next to the brake calipers. On a hard stop when the sensor detects one wheel stopping and another still going, these sensors send "pulses" to each wheel until the vehicle has stopped without the brakes having to lock up. The pulsiing is what you experienced and is a normal part of the ABS function.
Please rate this and let me know if it helped.
