SOURCE: 2001 Chevy Tahoe with ABS & Brake light on.

I hope you have the problem fixed by now, but, it is the ABS control under the truck. You need to go under the hood and open the fuse box and disconnect the 60 amp fuse for the ABS, this will turn it off before it burns up. This however will also cause the traction assist off light to stay lit all the time. To the fix the problem you can pay tons of money ($700 or so) to have the dealership install a ABS control and the problem will happen again over time. Or, remove it yourself, go on ebay and ship it off to a guy who repairs them for about $150 and you will never have the problem again. Also, if you wrap your cable ends with plastic and protect them good, you can still drive you truck while the part is being worked on. It takes about a week.

SOURCE: Need brake help with 2001 Silverado 2500 HD.

There is nothing special that you need to do. You need to make sure that you bleed the brake system starting at the master cylinder FIRST. You also want to make sure that you do not have any more leaks or open lines. Do not turn the car on until the brakes are bled or the air will go into the other circuits. The other thing to look out for is bad brake pads, If these are worn they can cause kind of a spongy pedal.

I would get your wheel sensors looked at. (Most vehicles have them incorporated into the wheel bearing for the front) If you are getting a false reading at a wheel, your ABS will engauge.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Can't get brake fluid to flow out antilock. Can't bleed brakes because no fluid coming out of the antilock system. Fliud going to antilock none coming out. Any fix on this.


did you read the FSM book first, or alldata.com pages on how to bleed your ABS system?, some cars require a scanner that can cycle the modulator to bleed out air.
97 626, ill look.
did you remove any parts , up stream of the modulator?
(called the hydraulic unit by mazda)
is the ABS lamp glowing?

here is page on HU swap. (would be worst case)
seems its not special bleeding type. "says "in the usual manor"

  1. If necessary, remove the fuel filter and igniter mounting nuts and move them out of the way.
  2. Remove the charcoal canister from the vehicle and if the vehicle is equipped with cruise control, remove the cruise control actuator.
  3. Disconnect the brake lines from the hydraulic unit. Correct reassembly is critical. Label or identify the lines before removal. Plug each line immediately after removal.
  4. Disconnect the electrical harness connectors to the hydraulic unit.
  5. Remove the 2 nuts holding the hydraulic unit. Remove the unit upwards.
0.) disconnect battery first.
The hydraulic unit is heavy; use care when removing it. The unit must remain in the upright position at all times and be protected from impact and shock.
  1. Set the unit upright supported by blocks on the workbench. The hydraulic unit must not be tilted or turned upside down. No component of the hydraulic unit should be loosened or disassembled.
  2. The bracket assemblies may be removed if desired.
To install:
  1. Install the brackets if removed.
  2. Install the hydraulic unit into the vehicle, keeping it upright at all times.
  3. Install the retaining nuts and tighten.
  4. Connect the electrical connectors.
  5. Connect each brake line to the proper port and double check the placement. Tighten each line to 113-190 inch lbs. (12.9-21.5 Nm).
  6. Fill the reservoir to the MAX line with brake fluid.
  7. Bleed the master cylinder, then bleed the brake lines.
  8. If removed, install the cruise control actuator and the charcoal canister.

Brake line on chevy silverado broken,need diagram to follow line back to box in middle of truck


Brake line diagrams dont exist like wiring diagrams do. If your truck has ABS, that's the ABS controller, and if not it's just the proportioning/metering valve.

How do to replace the abs control module?


If you are talking about just replacing the electronic ABS module (EBCM), it simply unplugs and unscrews from the hydraulic control unit. If you are talking about replacing the hydraulic control unit (HCU) then you must disconnect the EBCM. Disconnect all of the brake lines from the HCU. Remove the mounting bolts from the HCU and remove HCU from vehicle. Then you reverse th order to reinstall. Once it is installed you must use a scan tool to perform automated bleeding to get all the air out of the hydraulic unit and the rest of the brake system.

ABS light stays on sounds like a abs pump is staying on. Is there a pump for the abs system?


There is no seperate pump. The following lines will give you more details

Braking force and the tendency of the wheels to lock up are affected by a combination of factors such as the friction coefficient of the road surface, and the difference between the vehicle speed and the road wheel speed. The ABS prevents the road wheels from locking up during heavy braking by controlling the vehicle's brake system hydraulic pressure.
During normal braking, as the rotational speed of the wheel falls, no electric current flows from the ECU to the hydraulic unit. The solenoid valve is not energized. The brake master cylinder hydraulic pressure is applied to the brake unit, and the ABS is not involved. However, even though the ABS is passive during normal braking, its control module is constantly monitoring for rapid deceleration of any of the wheels.
If a wheel-speed sensor signals severe wheel deceleration - which means the wheel is likely to lock up - the ECU sends a current to the hydraulic unit. This energizes the solenoid valve. The action of the valve isolates the brake circuit from the master cylinder. This stops the braking pressure at that wheel from rising, and keeps it constant.
If the sensors signal the wheel is still decelerating too rapidly, the ECU sends a larger current to the hydraulic unit. The armature moves even further and opens the valve. It opens a passage from the brake circuit. Brake fluid is sent from the brake circuit back to the master cylinder. Pressure in the brake caliper circuit is reduced so that the wheel is braked less heavily.
If the wheel sensors indicate that lowering the brake pressure is letting the wheel accelerate again, the ECU stops sending current to the hydraulic unit and de-energizes the solenoid valve. This lets the pressure increase, so that the wheel is again decelerated.
This cycle repeats itself about four to six times per second.
It is normal in an ABS for the valves in the hydraulic control unit to keep changing position as they change the brake pressure that’s being applied. These changes in position may cause rapid pulsations to be felt through the brake pedal.

Can't get brake fluid from abs into lines after installing new brake line on a 2000 chevy silverado


I read this same problem all the time, the reason u can't bleed the lines is that a special tool is required that pluge into the ABS and holds the hydraulic valves in the ABS control open for bleeding, there is no way around this.

Brake line diagram


Brake Lines and Hoses
Double-walled steel line is used in the hydraulic lines between the brake master cylinder and the front tube connector, and between the brake master cylinder and the flexible brake hose at the rear wheels.
Double-flared brake lines provide good leak-proof connections.
When replacing hydraulic brake lines, hoses, or connectors, tighten all connections securely. After replacement, bleed the brake system; refer to Section 206-00 .
The wet appearance of the outer cover of the rubber brake hose is referred to as "sweating." This is a normal condition for neoprene rayon braid hose and is not a sign of leakage or cause for replacement of the hose.

Abs sensor light wont go off my 2005 polo


Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. ANTILOCK systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. The grinding noise could the the ABS pump or your brake pads could to worn to the metal backing and grinding against the brake rotors. I recommend a inspection soon for your safety.
