Hi
The ABS (anti-lock brake system) light comes on because the computer has detected a problem and set a code. The code will stay in the computer even if the light goes out. You need to have the system Scanned for codes. Once the cause of the code has been repaired the light can be shut off by clearing the code.
Most auto repair shops will have Scanners and all the equipment to Diagnose and repair the problem. And, Most auto parts stores can plug in a diagnostic scanning device into your vehicle to read the trouble codes at no cost if you purchase the parts necessary to repair the vehicle from them. The trouble codes can tell you THE AREA where the problem is with your ABS system. So it's wise to have a Tech check that circuit to isolate what the problem actually is.
In order to reset this light you need to have access to a Scan tool that does more than just read the codes. Other diagnostic equipment may be needed as well.
Fading Brake Pedal..
If you ever hold your foot on your brake pedal only to feel the brake pedal wither, wane and slowly fall to the floor, you have a break pedal fade and probably a leak in your brake master cylinder or some other kind of fluid leak.
Check for leaks sAs soon as possible, have your mechanic look and carefully check for leaks in your metal brake lines and brake hoses.
Look again for leaksIf after your mechanic repairs ALL leaks and your brake pedal still too easily yields to pressure, meaning your brakes aren’t firm "to the touch" take your vehicle back to your mechanic and insist he look again for leaks.
Better yet, go to another brake shop and have someone else look for a leak.
Mechanics being human, are subject to the same follies as all of us, don’t like being criticized, and therefore just might not be as diligent in looking for additional leaks as a new mechanic might be.
Low Brake Pedal...Certainly brake pedals have various heights in different makes and models of vehicles and even in similar vehicles
Adjust brake peda...lIf your brake pedal becomes lower than it used to be, you’ll need to have your brakes adjusted or your brakes have become worn.
Self Adjusting Brakes..With self-adjusting brakes, choose a safe place and try backing up your vehicle and then suddenly braking.
Do this three or four times, where you will not endanger pedestrians or hit another vehicle.
Get your brakes thoroughly checkedIf this process doesn’t bring your brake pedal back to its normal height, you’ll need your brakes thoroughly checked.

Thanks for contacting fixya.com

I have replaced 3 of 4 disc calipers on my pt cruiser. I have bleed brakes on all 4 calipers and have good brake pedal until I start the car.When I start the car the brake pedal goes to the floor.


Are you loosing brake fluid after you tighten that bleeder screw back? Your brake booster helps aid in the vacuum of the car - if you have an internal issue with that brake booster - you should check any vacuum lines coming off that booster. If you can answer with your year, make and model I can get you a more in depth answer - there are other things that can be causing your issues as well - from the master cylinder to other things. Good Luck. There's also a way to test that brake booster - do you have a pressure/vacuum gauge?

I have replaced 3 disc brake calipers on my 2001 pt cruiser. after bleeding all 4 brakes 3 times, I started the car and brake pedal goes to floor. is my brake booster shot?


Michael:

You must start bleeding the brakes at the wheel farthest from the master cylinder (usually the right rear), then the next farthest from the master cylinder, then the next, then the closest. If your master cylinder is at the left front of the car, start with the right rear, then the left rear, then the right front, then the left front. If you don't bleed the brakes in the correct order, you are just shifting the air in the lines from one line to another. Make sure that you close the bleeder before letting the brake pedal up, and the engine should not be running when you bleed the brakes... Make sure that the emergency brake is off. Make sure that the master cylinder does not run out of brake fluid at any time that you are bleeding the brakes.

Replaced rusted brake lines but did not replace valve in rear lines will this cause brake fade in 1995 bonneville


BY brake fade away I take it that you mean the pedal goes to the floor after you taken your foot off the brakes. . The valve you left out is a compensator valve that proportions the pressure between front and back to stop rear brake lock up and side skidding. I think the problem is in the master cyl in that the nonreturn valve under the second piston is not working and hold residiual pressure in the rear lines (Assuming they are drum brakes). If not you will need to bleed the m/cyl by cracking the lines at it one ata time and emptying the cylinder of trapped air allowing a full charge of fluid every time you pump the brakes.

99 ford explorer brake pedal goes to floor. Booster or master cyl. ?


Not likely that the booster is an issue. The booster would not be able to overcome the brake fluid compression.
First open and inspect all brakes for leaks, adjustment, etc. Check all brake lines.
So if no leaks, did the fluid go low in the MC? If so, pad consumption would eat more than a MC reservoir of fluid, and not require MC replacement, but rebleeding and top up of fluid. If the pads are worn, and you replace them, often this will expel air back through the MC.

If you determine the MC is faulty, bench bleed the new one before install, or you will have lots of problems getting air out....

Is the master cylinder good? a bad master can cause this also did you bleed the master first before bleeding at the wheel and also make sure the bleeder screw is clean, if the hose is good then theres only a few things, a bad master or a master that wasnt bleed, try bleeding the master first then try rebleeding the brakes.

I think I need to replace my brake booster.


Did you bench bleed the master before you installed it???? Engine off, have someone push the brake petal down and hold it down while you crack the brake line loose at the master,then tighten it and let up on the petal.Do this several times for each of the 2 lines at the master, only cracking it when the petal is being held all the way down.Repeat...Do them separately.Have some rags below the master to mop up the mess and keep the master from running out of fluid. Then do the gravity bleed one more time on each wheel cyl. and watch for a bubble of 2.
I hope this helps you.
Yes the booster sounds fine.

BRAKE BOOSTER?


A bad brake booster will result in a hard brake pedal, stiff and more effort required to stop the truck. Here are my questions to you, first, you said you replaced the master cylinder, did you bench bleed it before you installed it? If not, there IS still air in it, regardless of how much you bleed the brakes at the wheels. Second, when you bled the brakes, after changing the calipers and master cyl., did you also bleed the proportioning valve? Sometimes air can get trapped in the valve, and its almost impossible to get it out bleeding just the wheels. And lastly, when the brake light comes on, does the abs light also come on with it? Air can also get trapped in the abs control module too.

Brakes are mushy on my 2000 Ford Focus.


i would say your brakes are getting worn out because if the m.c. is low the only reason its low is because your brakes are worn down the fluid doesnt just disappear unless you have a leak just take look and see if anything is wet underneath.
