ABS light

[78F250SCCS]

After replacing my rear brake line and bleeding the system my abs light is now on. But it has just came on. I wasn't on when I took the truck out for a test run. The brakes feel spongy still. I'm thinking of bleeding the front lines again.

You need to bleed from the farthest point from the master cylinder and work forward. R-rear, L-rear, R-front, L-front. Make sure the master doesn't run low on fluid. ABS shouldn't come into play here.?

I can't remember if your truck has rear-only ABS or 4-wheel.

If it's rear-only, like my '97, just bleed the heck out of the rear brakes. You'll stop getting bubbles for a while, but keep going until you push all the air in the ABS unit all the way back and to the rear wheels.

Never dealt with 4-wheel...can't remember what you have to do for that.

some 4 wheel abs setups (primarily g.m.) require some specaility stuff to do a bleed job with. my '93 was rear abs only. im thinking 4 wheel abs didnt happen until the gen 4 (1998) when ford did away with twin I-beam/ttb, went to torsion bars and unit-bearing front hubs. i could be wrong about that. i agree on pushing more fluid through the rear lines. it took awhile to get it done on my truck when i had to replace the rear line going to the back axle from the proportioning valve.
