Air in the line. Could be a faulty caliper, to test a caliper clamp off the line with vice grip on each tyre and test pedal. If you get good pedal when a line is clamped you have found your problem caliper.

SOURCE: 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

Replaced rusted brake lines but did not replace valve in rear lines will this cause brake fade in 1995 bonneville

BY brake fade away I take it that you mean the pedal goes to the floor after you taken your foot off the brakes. . The valve you left out is a compensator valve that proportions the pressure between front and back to stop rear brake lock up and side skidding. I think the problem is in the master cyl in that the nonreturn valve under the second piston is not working and hold residiual pressure in the rear lines (Assuming they are drum brakes). If not you will need to bleed the m/cyl by cracking the lines at it one ata time and emptying the cylinder of trapped air allowing a full charge of fluid every time you pump the brakes.

I have a ford f150 that i have redone the brakes but all i getting is a brake pedal and then goes to floor

Bleed your brakes, starting with Right rear, left rear, right front and ending with left front. You have air in the lines or a bad master cylinder. Bleeding is the cheaper of two options.

1999 Ford E350 van problem: brake pedal is soft; have replaced master cylinder, rear wheel cylinders, rear brake shoes and drums, front calipers, rotors and discs; have bled master cylinder before...

Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

Brake fluid is not coming out when i open the bleeder at the rear wheel on 89 ford tempo

Good day Robert W73, there should be a metal pipe leading from the master cyclinder to the rear wheels and to the front wheels. Try loosening the pipe on the master cylinder and pump the brakes. It might be that there is an air lock in the master cylinder. By loosening this pipe the air forsing the brake fluid back will be released. As soon as the clean brake fluid comes out of the pipe tighten the pipe again and pump the brakes. Then step on the brake pedal and hold it in, while the brake pedal is depressed open the bleeding nipple and close it again. Repeat this procedure till you have clean brake fluid comming out of the bleeding nipple. Just remember to bleed all the wheels starting at the wheel furthest from the master cylinder and working your way to the closest wheel.

I hope this helps. If it does not help you might need to replace the seals on the inside of the master cylinder or you will have to replace the master cylinder itself as there might be pit marks on the inside causing the hydraulic fluid to bypass the seals.

The brake pedal goes to the floor with no resistance. I have replaced both rear wheel cylinders and master cylinder, problem persists.

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.

My brakes go to the floor what could it be I changed the master cylider its a 2002 ford escape

Did you bench bleed the replacement master cylinder?If you did and there is NO air in the braking system then look for improperly adjusted rear brakes[if drum],or a siezed caliper slide[s] if disc brake equipped.

I replaced the mas cyl 2004 ford explorer. Gas padal won't work

You need to bleed the air from the system. First if you replaced the master cylinder you need to bleep both ports that the line hook too. Then hook the lines up and bleed all four corners of the vehicles brakes starting with the right rear since it is the furthest point away from the master cylinder. As you bleed the system remember to refill the master so you don't' ingest more air into the system again.
