Experienced mechanics share their insights in answering this question :
Hello. If the brake pedal is going to the floor then that means that it is not building pressure. If the brake system has been fully bled and there is no air in it then most of the time it is a bad master cylinder or it can be caused by a bad ABS module. If the brake fluid was low and if air got into the system then the only way to properly bleed it is with a scan tool that would allow you to open and close the valves in the ABS unit. Air gets trapped in these easily if the brake fluid gets low. This can also explain why the brakes are locking up. I would usually use my scan tool to bleed the system out first before going any further. I would also scan the brake control module to see what it is reading as a fault. If there is no air in the system and if there is no prominent code then I would replace the master cylinder first. If you want to check out why your brakes are locking up, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

Four Reasons Your Anti-lock Brake System Light Can Come On
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off.
Firstly, you should check your brake fluid reservoir to ensure that the levels aren`t too low, as the ABS warning light can be activated if the levels of brake fluid have dropped. If this is clearly an issue, you can top the brake fluid up yourself, which should cause the ABS light to go off.
The ABS warning light is an icon on a vehicle`s dashboard that alerts the driver to a potential problem with the ABS (Anti-lock Braking System). The ABS on a car, truck, or SUV prevents the wheels from locking up when a driver slams on the brake pedal in an emergency situation or on a wet or slippery surface.
Wheel speed sensors are often called ABS sensors. You`ll find them mounted on the axles of all ABS equipped vehicles. Look for this sensor on your wheel hubs, near the brake rotors. You`ll find the rear wheel speed sensor mounted on the rear axle housing or wheel cylinder.
The anti-lock function will stop working properly, which may increase the distance it takes to safely stop your vehicle. The rear tires will lock, which will increase vehicle swing on turns and may make your vehicle more difficult to control.
The most common ABS problems occur when sensors become contaminated with debris or metal shavings. Malfunctions also occur when sensor wiring becomes damaged, resulting in intermittent or no continuity.
Sometimes a blown fuse to the ABS can cause the light to come on and stay on. Fuses are easy to blow, so sometimes it`s an easy fix to check.
Resetting Your ABS Dashboard Warning Light
Step One: Disconnect the positive cable from your car battery. Then, hold down the brake pedal to drain the vehicle`s electrical system. This will result in a reset of the car`s central computer. Plug the cable back in to restore power.
When your car`s ABS light comes on, it means there is a problem with your vehicle`s braking system. You need to address this issue; otherwise, it could make your car unsafe to drive. ABS is a type of braking system used in all cars produced since Sept. 1, 2011.
Sometimes the ABS warning light may illuminate even when your brakes work fine. This often means that the hardware that makes up your braking system is working well. The problem may lie with the sensors that activate the antilock braking system.
One reason your vehicle`s ABS light is on is because it may be sensing abnormally low levels of brake fluid. You`ll be able to notice if your brake fluid is low by the way your car brakes.
If both your ABS Light and brake system light come on, this is an emergency and you need to stop driving right away. Have your entire brake system inspected by a certified mechanic, such as one from YourMechanic.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.
brake and abs light won’t go off after replaceing brake pads and ft. rotors.
ANSWER : Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car’s ECU. When the ECU senses an abnormal speed given specific conditions, it engages the ABS or traction control as needed to control the vehicle properly and safely. In your case these sensors may have been bumped or need to be reset due to the movement when the brakes were replaced. I would suggest having a professional from YourMechanic come to your home to diagnose your ABS and traction control system.
I replaced the brake light switch. Gear lever unlocked because it had locked. Now the brakes feel hard.
ANSWER : Hi, thanks for writing in. You need to check the brake switch install adjustment. You may have the switch adjusted too tight and it is holding the the brake pedal partly down. This will cause the brake master cylinder to not release the brakes when you let off the pedal. Readjust the switch away from the pedal until you feel some free play again in the pedal. This should fix the problem. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
Brake light and abs light on, my brakes are soft ( needs to be replaced ) if I replace brakes will both lights go off?
ANSWER : A soft brake pedal generally indicates a hydraulic issue with the brake system. If the hydraulic system has a leak or a faulty seal in components such as the brake master cylinder of ABS pump, the brake system will not operate with the correct pressure. Worn brake pads may make the brake pedal travel farther than say new brake pads, but this generally does not cause a "soft" brake pedal. Replacing brake pads may not turn the ABS and BRAKE lights off. An abs system inspection should be performed by a certified technician before replacing any parts that may or may not correct your issue. I cannot predict if you will have a further issue but as far as is it unsafe ? Yes, driving with a possible hydraulic fault with the brake system is very unsafe as the brakes may fail entirely.
When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.
