sounds like you need to bleed the brakes again. Get a clear hose and put it on the bleed nipple on the slave cylinder so you can see the air bubbles in the fluid. bleed the clutch until there are no air bubbles in that clear hose. Even the little tiny bubbles can add up to lots of air in the system.

03 F150 spongey brakes after replaceing brake cylender and bleeding brakes?

This sounds like a bad brake line, these trucks are famous for rotted lines behind gas tank, make sure there are no leaks, this sounds like a leak or a defective master cylinder, if this is the same problem then i would say it is a line also check the rear brakes for leaking wheel cylinders unless you have rear disc brakes, check calipers for leaks.

Take a good look at brake system for leaks, hold brake pedal a few times and let is sink to floor , do it about ten times and then look for a leak, good day

I am working on a 1993 f-350 with a 7.3 diesel the truck came to me with the brake pedal going to the floor... the customer had already put 3 new master cylenders on it along with a new brake booster......

I would ask where you got the master cylinders from. Were they new, or rebuilt? If the front brake pads look good and no apparent problems from the calipers, it can only be 2 problems. First, is there a leak somewhere in the system. If you have confirmed that there is none, then the master cylinder is 'bleeding' from front to back. Air wouldn't be a problem as you seem to have bled the brakes well, but the only sure way to know is using a bleeder. They run from a simple hand vacuum device to an air powered device which forces brake fluid thru the system.
Since your 'customer' replaced the booster, make sure the plunger rod is set correctly. Perhaps it is not set at the correct length, in which case you will never get a pedal. Diagnosis for this is a pressure tester to see if any pressure is being generated by the calipers.
Good luck. Hope this helps.

I re placed the master cylender and now i got no brakes in the back at all

You will need to bleed the system. If you did not bleed the master when you installed it, if it has bleed valves, use them to get the air out...if not, step down lightly on the brake and at the same time, loosen the line fitting a bit till fluid comes out. Then, bleed rear brakes the same way using bleed screws on the cylinders or calipers. Begin at right rear, then left rear, then r/f and l/f. Don't permit the master to run dry or you will have to begin all over again. Also check all lines to make sure nothing under the vehicle is leaking. While bleeding don't take your foot off the brake till the bleeder you are working on is closed, and don't push really hard on brake as that can damage the cylinder internals.

My brake pedal slowly goes to the floor and the engine make a whining noise on my 2001 F-250 diesel. Why?

wellyou may have one of a couple of different problems.
1. if you have recently wrked on the brake system you have air in the system and need to bleed it.

2. if you are lossing fluid you have a leak in a line or caliper or rear brake cylnder

3. your Master cylender is going bad

your engine is making noise do to the power boost on the brakes being maxed out

Hard to push brake pedal down to stop.

1. Check brake fluid level and look for leaks in the brake lines and at the calipers.
2. Bleed the brake fluid completely and replace with fresh fluid (google search: how to bleed brakes). Then bleed air by having someone press the brake pedal 4-5 times, then press and hold while you open the bleed valve and close when fluid streams out. start with the rear wheel (if 4wheel disc brakes) then move to the front.
3. Replace Master Cylinder (sorry, but if 1 or 2 didn't fix it, this is the last option) This is usually over $150, and will involve step 2 again when completed.

Good luck, hope this helps.

Brake problems

The brakes don't create air, so it may be your bleeding procedure.

Always start at the right rear wheel, then left rear, then right front, then left front. Pump the pedal 3, maybe 4 times before you check the reservoir. If it ever goes dry, you MUST start over.

If you still get dirty fluid from the lines, then you have not purged all the air from the system. The clean fluid chases the dirty fluid, with a bubble of air in between.

You must also be sure to close the wheel cylinder port while the pedal is depressed, open when the pedal is being depressed. If the port is open when the pedal is released, air will be sucked back into the line.
