1986 Ford E-150 Brake line problem

obviously not or you would have brakes

there is still air in the lines and that can be from a master cylinder that has an air lock and is not allowing fluid to pump

Take it to an accredited brake specialist for diagnosis and brake bleed

when bleeding the brakes , it is a 2 person operation and each line ( starting at the longest line is operated until only solid fluid comes out when the bleed screw is operated

Because when you start it the brake booster will start working, start bleed on wheel farthest from master cylinder and work closer, one at a time pump up and bleed each line at least once after you don't see air anymore...

I would start by bleeding the air out of the brake system starting at the longest line first. Check for fluid in the master cylinder . IF you have problems bleeding then undo the lines at the master cylinder and using your fingers a valves bleed the air out and prime the master cylinder first then bleed the system

Sounds like it still has some air in the system or a bad master cylinder. First try bleeding all air, there is definitely some air left in the lines and this is most probably causing the problem. Bled the lines at the bleeder screws on the calipers. ---------- There is air left in the brake line.Any time the brake system is opened to replace brake lines, caliper, pads etc etc.Mostly the air enters the system, and that air has to be completely bleed.Otherwise the same symptoms , what you are getting will be noticed.-------- Brakes can be bled manually, with a power bleeder, injector tool or vacuum bleeder.IIt does not make any difference which method you use as long as all the lines and components are flushed with enough fluid to remove any trapped air bubbles or air pockets.----
The most common bleeding procedure is to bleed the brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car or truck, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.--------- When the complete air is bleed from the line, the brake should be firm when car is on.In your case brake brake pedal is loose and goes almost to the floor when car is ON.This is due to Air in the line.Get the complete air bleed from brake line.------- This will help.Thanks.Helpmech

Is the brake-light on? I understand what you replaced but what was the procedure that you followed to bleed the brakes? Did you bench bleed the master? After installing the new master, did you bleed air out of the proportioning valve, and all four wheels. You need to start with the F/L wheel and finish with the R/R wheel. Unless you own and are using an automatic brake bleeding unit. You will have to get another person to help bleed them.

You still have air in the lines keep bleeding

Start by bleeding master cylinder, will take two to do this, have some pump the brake paddle about ten time every time, have them pump it and hold it down while you open brake line when paddle goes to floor close and pump again ( one of the brake lines at the master cylinder ), keep doing that till no more air comes out, then do the other brake line at master cylinder again till no more air comes out, keep an eye on master cylinder that it don't go low on brake fluid or you will have to start all over again, how go to right rear wheel and bleed till no more air comes out ( have them pump brake paddle and hold while you open and close bleeder valve, do not let them release brake paddle till you have close bleeder valve, keep doing that till no more air comes out, then go to right rear, then left rear, from there right front and last left front.Hope this was very helpful, good luck.

start at the passenger rear tire, have someone PUMP up brakes and hold pressure on them, release pressure by locating small bleeder screw, loosen screw 1/4 turn, brake fluid/air should come out, after brake petal reaches floor tighten bleeder, repeat process until only brake fluid comes out. go to driver side rear repeat, go to pass. side front repeat, go to driver side front repeat, after each bleeding make sure you check brake fluid in reservoir.

SOUND LIKE AIR IN BRAKE LINES.CHECK BRAKE FLUID LEVEL MAKE SURE ITS NOT LOW. CHECK ALL BRAKE HOSES AND BRAKE LINES. FOR LEAKS. YOU HAVE TO BLEED BRAKES.IF ALL IS GOOD.YOU HAVE MASTER CYLINDER AND ABS BRAKE FAILURE.HAVE DEALERSHIP FIX IT.THEY HAVE THE EQUIPMENT TO TROUBLE SHOOT AND BLEED THE BRAKE SYSTEM.

Hello

With regards to the brake lights, you need to replace your brake switch located under your brake pedal.

With regards to spongy pedal, sounds like air in the line you need to bleed the brakes via the bleed nipple on each caliper and check your brake fluid.

hope this helps.

Thanks
