    checked the booster and all valves. no leakes found

    The check valve only flows air one way? Changing pads doesn't cause pedal to go to floor-- Explain

  • sheldon Dec 08, 2012

    engine shut off push on the pedal and the fluid level rises release the pedal the fluid level goes down. not sure if that the way it supoosed to be

  • Anonymous Dec 08, 2012

    I would bleed all 4 corners & maybe change the rubber flex hoses,they may be restricted inside

  • sheldon Dec 08, 2012

SOURCE: 97 ford e350 brake pedal goes to the floor...

1992 Ford E350-same brake concern, pedal goes to floor! Replaced master cylinder, brake booster, frt pads and rotors. Replaced rear shoes wheel cylinders, and drums, vehicle stops but pedal goes to floor, squeaze off rear flex hose and pedal is solid. Takes 2 > 3 pumps normally to get hard pedal then goes to floor, wouding in longer brake wheel cylinder pins would fix the problem???? P/S hope you can help.

SOURCE: brake problem with 95 ford bronco

hello again, Your brakes are probably the most important part of your car. Without an intake system, you'll just sit there. But at least you won't hit a tree while you're just sitting there! Seriously, brakes aren't something to play around with. If your car is having a braking problem, whether it's weak brakes, a mushy pedal, grinding sounds - whatever your brake problem is, you need to troubleshoot and repair it as soon as possible. We'll help you diagnose your braking problem so you know what repairs to make. Brake Pedal Goes Too Far Down to Stop. If you step on the brake pedal and it feels like it's going too far down before you start to slow, you might have the following problems:

  • Low Brake Fluid Level: Check your brake fluid. If it's low, top it off to the mark on the side of the reservoir.
  • Contaminated Brake Fluid: Even though your brakes operate in a closed system, contaminants can still work there way into the works. Air can enter the system through the smallest hole, and you can end up with water in the system from condensation and other means. There's not really any way to check for this, but bleeding your brakes will remove the bad stuff and replace it with new fluid.
  • Worn Brake Pads: Your brakes should never wear low enough to cause your brake pedal to feel low, they'll scream at you before then. But if they do get very low, you might have this problem. Replace your brake pads as soon as possible. Of course, this can be avoided with regular brake inspection.
  • Bad Brake Power Boost Unit Finally, if your brake booster goes bad you'll have low brake pedal issues. Most brake boosters are vacuum controlled, so a special vacuum measurement device that connects to the brake booster is needed to check it. If it's bad, you'll have to replace the boost unit.

88 Bronco 2 4x4 2.9L has air in the hydraulic clutch line. I have been pumping the pedal and bleeding it for hours, including cracking the bleed screw with the pedal depressed. nothing seems to work.


Try to find where the air is entering the clutch line. When you bleed the cylinder you cannot drain the reservoir completely when bleeding. If you do then you'll only pump more air into the system.

Brake pedal goes to the floor only when engine is running. Pedal is perfect with engine off.


your power brake booster is blown out
the seal has a leak in it
run the truck for 3 minutes and shut it off. with the windows up listen carefully while you gently apply the brakes
listen for a hissing sound of air leaking.
the sound of these leaking is a very soft sound
