Abs light stats on after changing discs pads rear shoes [email protected]

Pedal, not peddle. First make sure reservoir is full at the brake master cylinder. Then check your brake pads (for disc brakes) and/or brake shoes (for drum brakes). When the pads or shoes are very worn down, you will get a low pedal. If you have disc brakes on the front and drums on the rear wheels, first try just replacing the front brake pads. If you get a good pedal after the front is done, many people tend to let the rear brake shoes go unless they are making noise. These systems are designed to put most of the braking force on the front discs, so the rear shoes do not need changing as often.

Did you bench bleed the MC before installing it? If not, that's the problem. MUST be bench bled or you'll always have air. If brakes lights are on, the brake switch is out of adjustment OR (since you replaced the MC), the push rod is out of adjustment

Master cylinder and/or brake booster could be the problem. A tiny bit of air in the system will effect your braking abilty. A fault in the ABS system would prompt the computer to trigger the ABS light. If you have brake shoes on the rear, make sure they are properly adjusted. Hope this helps.

A common problem with fords. The brake pads and shoes are semi-metalic, and the abs sensor is magnetic. With time and wear from the old pads, and dirts and road grime, All of these things build up on the sensor. Fortunately this is usually a simple fix. If you don't already have this on had, go to you closest parts store and get a can of Brake Cleaner. The cheapest will do just fine. Locate the abs sensor ( usually on the hub assembly ) and spray them off. Be generous with the brake cleaner. By the time you crank your car back up, this light should be gone.

ABS is anti lock braking system,which helps to stop car in various conditions.Wet/slippery etc
Sensors are located on all brakes
You need to go to your local auto electrician who will plug in scanner to locate fault

That's to be expected and is completely normal.

Rear brake shoes as fitted to drum brakes can typically last up to 60k miles with periodic adjustments, but you have rear disc brakes and the shoes will typically last half of that.

Also, modern brake pads no longer contain asbestos and are now made using harder metallic compounds; the direct result is that brake discs (US=rotors) are also considered to be consumable items as they are worn down by the harder pads. It's not unusual to have to replace front discs every other pad change and rear ones with every pad change; in both cases the mileage will typically be around 30k miles on most models.

is it the front or rear locking up? you really have to have this truck loaded (load valve under bed) before the back brakes come on and i think these are the same as my 1999 2500 where the rear is only abs, and not on the front..dumb design i know, but thats how it is...determining if its rear abs only and which axle is locking up will help pin point the problem...i put 100000 miles on my dodge since i got it in 2001 and i put 8 sets of pads on the front and just changed the rear lining and thats only because the rear wheel cylinder was leaking causing the rear brakes to lock up..

check retaining clip on hand brake shoes behind rear rotor,check if shoes arent ondone from clip,check calyper and guide bolts for binding.

Did you get the rotors machined to specs or just change the pads.If not machined suggest you get them checked to see wether they should have been.This affects ABS equipped vehicles more severely
