I am having an issue with my 97 dodge 12v where my abs brake light come on when I apply the brake. I can tap the pedal and it will shut off, though comes on again when I reapply the brake. Also has a soft pedal for about 3 inch push before it goes to norm resistance. I have read the closed forums and none of those solutions seem to be mine. Any ideas would be helpful. Thanks

 

The light comes on if there is a difference in pressure between front and rear brakes, so it sounds like there is air in the system somewhere...? Or there may be a leak somewhere. Can you see any leaks in any lines? The wheel cylinders inside your rear drums can leak and go unnoticed for a while... Check also the boot on the inside of the firewall where the rod from the brake pedal goes into the master cylinder, as the MC can leak back into the cab.

Basically, make sure the master cylinder is full of fluid, and if you find no leaks, try bleeding the system.



But.....You say you can push the pedal about 3" and then pedal goes to normal? That makes me think there is a good chance it is the master cylinder...

 

that much peddle travel could also be the rear brakes way out of adjustment or broken hardware or a front wheel bearing getting loose and allowing the rotor to push the piston too far into the caliper

 

Leaking brake line??

 

All it took was a brake system flush. Apparently, there was a bit of grit in the lines. Thanks for the help.

 

wheel bearing could be bad on the front also.

 

good to know you found the problem

 

Good deal. Going to close the thread.
