Brake problems We keep bleeding the brakes and every few days the need to be bleed again. We replaced the master cylender last summer. What else could be causing this? It only gets air in the front drivers side.

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.

My break pedal goes all the way to the floor . I replaced brake rotors master cylinder, and Break booster. I had to bleed the brake and still pedal still goes to the floor


You still have air in the system.(not bled properly) If you let the Master cylinder drop down to nothing then you need to bench bleed that before bleeding the lines again.

Iv'ed just replaced a brake master cylender now the brakes seam spongy and it takes a little distance to stop


It's most likely you still have some air in the system. Bleed the whole brake system again, starting at the farthest wheeland working your way back to the closest one. You may have to do this more than once, just leave a day or two between bleeding.This will work the air down toward the wheel cylinders.

Brake master cylender


When replacing a master cylinder I usually bleed at the cylinder not by trying to move the air all the way to the brakes. Also I don't pump the brakes instead I open the bleed screw and have someone push the brake pedal to the floor and hold it until I close the valve.

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

Changed the master cylender and vacuum booster and blead the system by the book and still cant get breaks without pumping them.


There must be air in the system some where. i am not sure of the year ,make and model of this van and also not sure of the brake system, for example if you have drum brakes in the rear then first adjust them.
The next step is to fill the master cylinder, make sure there are no leak anywhere.Next step start at the master cylinder, at the line to master do not worry about abs system. have someone inside ready to pump brake pedal and hold.Have them pump pedal three times and hold pedal with a little pressure.make sure as you open the bleeder they push on pedal and keep foot on brake until you tell them to pump again. the pedal is to be pumped three times every times.
With pedal pumped start at master lines, open one allow to bleed a little then close and move to next and allow to bleed. if master has more than two lines then pump again and do two, open one and close then open two and close then pump again. After master is bleed a few times and no air comes out then move to right rear wheel, pump three times and hold while you open bleeder, this is to be done about four times to make sure you get a good flow of fluid with no air .
NOTE: always keep master cylinder full, check after each wheel. make sure the person pumping the brakes does not lift until you say and the bleeder is closed. After the right rear wheel you will move to left rear and then right front wheel and last is the left front wheel.
Make sure there are no bad wheel bearings, lift wheel of the ground and grab and check for movement by pulling wheel out and in from top to bottom, the last thing is make sure the caliper slides are free moving.
If the caliper does not slide on the bracket freely then the piston will not stay on pad and pedal will need to be pumped to get a pedal. good day.

How do I bleed the brakes?


I will explain it to you the best way i know how..take the cap off of the master cylender, make sure its full of fluid, leave cap off, get a partner. when you bleed brakes you always start at the wheel farthest away from the master cylender and work your way to it, so start at the rear passengers wheel, have your partner pump the brake pedal 12 or so times, and hold pressure against it ( TELL THEM NOT TO LET UP, UNTIL YOU TELL THEM) crack the bleed plug, let air/fluid out, re snug the plus.( now they can let off.. if they let off of the pedal before the bleeder is tight, it will pull air in the system, and you will hafta start all over again.) Do this a few times, until you get a steady flow of fluid, with no air bubbles. After this one is bled, top back off the master cylender, then go to the back Drivers wheel, do process over again, between every wheel top off master cylender. then go to passengers front, and then finally drivers front... hope i explained this good enough for you to understand.. and if you have never messed with brake fluid before DO NOT let any of the fluid touch the paint on your vehicle, it will strip it off. hope this helps

How do i bleed the brakes


you will need another person with you. take the cap off of the master cylender, and make sure it is full of fluid. start at the wheel farthest away from the master cylender. so the back passengers side, have your partner pump the brakes about 10 times and hold pressure against the brake. ( Tell them not to let off until you tell them.) loosen the bleeder, fluid and air will squirt out, tighten bleeder screw back up, ( they can now let off of the pedal). do it over a couple or three times until you get a steady streem of fluid with no air. then go to the drivers side back, then passengers front, and end up at drivers front. Keep a check on the master cylender that it doesnt get empty, keep fluid in it or you will need to start over again.. hope i explained this good enough for you to understand.. whatever you do make sure your partner knows not to let off of the brake petal, until you have the bleed screw tight, and tell them to let off.

you may need to bench bleed your master cylinder to keep the air from filling the lines and making bleeding more difficult

here is a link to a "how to"...good luck (I hate brakes)

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.

1989 Chevy pickup we replaced all of the break lines and master


There is probably still just some air in the system, it only takes a small amount to have no pedal. Did you bench bleed the master cyl before installing? Start bleeding the brakes again, start with the wheel the greatest distance from the master cyl. bleeding until no air is evident, working your way closer to the master cyl, doing the closest wheel to it last. Check all the new brake line connections. A slightly loose connection would allow air into the system, making it impossible to bleed it all out. Make sure the master cyl level never drops too low, or you will be pulling in air and have to start all over. Good luck.
