I want to puul fuse for abs brakes.I broke the rear line and now I can't get any brake peddle.Loosened line where we hooked to brake and let it drain until fluid ran free.still no peddleWhen engine is not running brakes is hard but when running peddle goes to floor.

No reset on 98"s bleed all the lines. Replace all the lines in my opinion...That's what I do. we are talking almost 15 years of rust and fatigue...

You have valves in the abs block altho the motor might be working it could the valve is not working is the load sensing vavle working on the rear axle. Check the master cylinder is pumping fluid to the pump then check if fluid is coming from the from abs pump when brake peddle is applied. Ps don't forget you might have to bleed brakes once the pipes have been slackened

Here's a basic rundown on brake lines: Brake lines start at your master cylinder go to a main proportioning/combination valve to adjust brake pressure to front/rear of vehicle from here your brake lines will either go directly into your calipers on a disk brake setup or to a wheel cylinder on a drum brake set up. ABS or Antilock braking system is a computer assisted braking which generates numerous pulses per second to eliminate locking your brakes and loosing control of your vehicle. There are components which are needed by the system but as to hooking brake line to abs no. You can get preformed/exact replacement brake lines from dealer or some parts stores or you can get the correct length and a piping/tubing bender and form your own. Hope this clarifies things a bit. Need anything else let me know

when you bled the lines ,Did you start from the wheel farthest from the resevoir?

COULD BE DIRTY FUEL INJECTORS OR STOPPED UP FUEL PUMP FILTER WHICH IS ON THE FUEL PUMP.EXCESSIVE BRAKE PEDAL TRAVEL CAN BE BRAKE POWER BOOSTER NOT GETTING ENOUGH ENGINE VACCUM OR BRAKE BOOSTER CHECK VALVE OR BRAKE BOOSTER FAULTY.YOU COULD HAVE LOW BRAKE FLUID LEVEL IN MASTER CYLINDER.OR NEW BRAKE SHOES HAS NOT BROKE IN.

You probably have air between the master cylinder and the abs pump. Fill the reservior and have someone pump the brake and bleed the primary lines at the abs pump. Good luck.

there is air trapped in the portion valve read up on this autozone .com might have this in there repair manual if not usually ford has a electronic scan tool for this to reset it

that is one of the wosrt ABS system it dose cause a soft peddle but you can sometimes adjust up the rear brakes to help this problem,also find a dirt road and slam on the brakes just enough to cause the ABS pump to kick on it will also give you a better peddle

Yes air gets into the hole system. You need to bleed all 4 wheels.

ABS engaging possible due to faulty speed sensor.
Pull 60A ABS fuse to disable to see if the problem goes away.
