Open Question

I replaced my front driver and passenger brake lines, bled them, and now when I go over 20 mph, my ABS light comes on. Also, my brake light comes on as well (together). How do I fix this?

ABS CHECK LIGHT DOESNT COME ON WHEN YOU TURN KEY ON


1. I would not be concerned because if there was a failure in the ABS you would definitely get an ABS warning light and the ABS and most likely the stability control/traction control systems (with added warning lights) will all switch off .

2. You can test if the ABS is operational. On a very quiet damp surface, straight, wide road( with NO other cars around), apply your brakes hard from a very low speed - up to 20 mph ONLY driving in a straight line - until the car stops. The front brakes should attempt to lock up under hard braking and if the ABS is operational you will feel it kick in and the brake pedal will pulsate as the ABS constantly allows brake pressure and then releases it to prevent the wheels from locking up on the damp road. If the ABS does not kick in be ready to release the brake pedal quickly to allow the wheels to rotate so you can steer the car safely. Without the ABS the front wheels should begin to lock up on the damp road surface due to the low level of tire grip. ONLY test this at very low speed and ONLY when driving in a straight line on a straight section of wide road with no other vehicles around.

No brake pressure


When you bled the system was fluid coming out the bleeder valves?
Where the bleeder valves closed off with the brake pedal fully depressed?
Is the fluid reservoir cap ok?
Is the master cylinder ok?

Have you checked your brake system for leaks? You may have air in the system that can cause the ABS light to come on. I had a similar problem with my last truck. ABS light came on and found a hole rusted through one of my rear brake lines.

Try checking with either propane or water mist on all hoses and surfaces where generated vacuum could escape.

Activator rod from Brake pedal to Master cylinder can be adjustable on some models.

try bleeding your ABS block first, if that doesn not work could need a master or proportioning vavle. Some scan tools are capable of bleeding the ABS system on some vehicles, and some you have to bleed manually.

I have a 2000 expedition with a soft brake pedal. I replaced the master that didn't help. It has all new brakes .system has been bled a few times and nothing has changed


Hello, Some of these systems require a Power Brake Bleeder to clear the lines of air. The bleed routine is to go from the farthest to the closest axle on bleeding. Do passengers rear, drivers rear, passengers front, then finally drivers front.

You may have a problem with the valving in the ABS unit. You would need line pressure gauges to measure what is going on inside the unit. You may be able to rent a Power Bleeder or get one free with a deposit at Autozone, Oreillys, or Advance to name a few.

The ABS can also be scanned with the proper scanner. You may be able to rent a tool for this or again check with the Autoparts stores.
