Adjust your rear brake shoes. Then rebleed the system. Start at the master cylinder Bleed master first then the wheel furthest away from the master (right rear then left rear then right front then left front. Do that and your pedal should be good.

1994 Ford F 350 4X4 Diesel. Brake pedal goes to


You need to crawl under the truck and inspect each brake line for leaks. You also need to check wheel cylinders and calipers. The chances are pretty good that you will find a small leak in a line or a wheel cylinder leaking, pay close attention to the rear of the truck because that is normally where these problems occur. Hope this helps.

Hi. I have a 1990 Ford F350 diesel UHaul with no


when you replace the master cylinder, your are supposed to pump it up manually before you install it. If you don't, you'll have to sit there and pump the brake pedal a couple of thousand times as one almost microscopic air bubble at a time escapes the pressure tube and back fills with fluid. once you can push the pedal repeatedly without any bubbles escaping into the reservoir, then bleed the brakes. Starting with the farthest, usually the Right Rear and work your way up. Make sure you keep the fluid level topped off. If it sucks air once, you have to start all over.

Fading brake pedal


Perfect well at this point i would say that tha abs valve is bypassing fluid. If you can un hook the line that comes into the abs valve and plug it and try and bleed the system where you cap the line going into the abs valve. If you get a good pedal after pluging the line going into the abs valve this tells me that the abs valve is bypassing fluid give it a try i have ran into this a few time and the abs valve has been bad. Also can you rate this sluton also i do hits on my own free time thanks good luck

1997 Ford F-350 7.3 L Diesel..........brake failure


With no leaks and a little braking action returning by pumping the pedal I would suggest looking into a master cylinder. Low brake fluid level in the master cylinder will cause the brake warning light to illuminate (possibly, also the ABS light).

If the truck has the 7.3L diesel, it will have a vacuum pump which supplies vacuum for all vacuum accessories. I believe if the vacuum level drops below 10 in. of Hg, the brake light will illuminate. If the vacuum pump fails you'll know it as the brake pedal will require quite a bit of effort to effect any braking effort.
