Question about Ford Cars & Trucks
Posted by Anonymous on
I've 2 ideas:
1) Is it possible that the master cylinder reservoir has been overfilled?
2) Follow through this with me. As soon as I'm wrong, it's not relevant. Older vehicle....Possibly double acting master cylinder which means there could be 2 separate lines coming out of the master cylinder. One of the seals in the master cylinder may have failed, thus squirting brake fluid inside the master cylinder instead of pressurizing that part of the brake system. The brakes will work, but only for the wheels served by the functioning part.
A test for this could be to put a pressure guage on the outlets. The field test would be to drive at about 10 MPH in a safe area, and STAND on the brake pedal. If only two of the brakes lock up, you. will need to replace the master cylinder.

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

Did you put fresh fluid in the master cylinder? I really think you still have air in the lines. To bleed manually, start with the bleeder the greatest distance from the master cylinder, car running, helper pushing down about half way on brake pedal and releasing 3 times, on 3rd time, holding pedal down to half way depressed point while you open the bleeder valve. Repeat until you are sure all air has been flushed out. Check master cyl reservoir level often, because if it gets low and you **** air into the system, you have to start all over again. Go to wheel next greatest distance from master cyl, repeat above, working your way to wheel closest to master cyl last.

it could be that the master cylinder is bad or the brake booster is bad also check the vacum hose going to the brake booster if it has a hole in it it will lose pressure and make the engine lose rpms

do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.
