Cant bleed my brakes on ford escape no fluid will come out of the master cylinder


Are you able to bleed the brake from the caliper you changed? If you can you may have a plugged bleeder at the master cylinder or the new one did not get drilled all the way through so the fluid comes out. Does the truck have ABS brakes? I am assuming so but not sure, if so you may have to reposition the valve in the line that cuts off the leak and shifts the fluid to the rear wheels in this case, it is in the lines, but at that I would think you still should be able to bleed the master cylinder. You may need to bleed all of the wheels before you can bleed the master.

2001 ford windstar lx master cylinder new i replaced but abs n brake light come on


Needs to have code reset for abs by a obd2 code reader with abs or find a parts house or shop that will reset it. Brake light coming on did you bleed the master cylinder out by connecting rubber lines to ths plastic insert ******* then acuating the master cylinder til all air is pumped out of master cylinder if that was not done then you will need to bleed all brakes until air is out of system that should turn brake light off

I change my master cylinder for my brakes and now I have no brakes what could be my problem to that


you must have a lot of air in system. the brakes need bleed to let the air out of system. did you bench bleed the master cylinder before putting it on car ! if not thats why no brakes. to bench bleed a new master cylinder, put it in a vise. fill it full or the proper level of brake fluid. push on the plunger with a dowel or another object. pump it till all air is out of master cylinder, you can tell when no air. it will be all fluid coming out of cylinder. keep checking brake fluid in master cylinder.make sure you push plunger in all the way.when all air is gone replace on car. if you do not loose any fluid from the master cylinder lines, then you can replace it without having air in system. bleed each wheel if needed. good-day!

How to replace the brake master cilinder


Remove the lines running to it, and then unbolt it from whatever surface it's mounted to.
You will need to BENCH BLEED your NEW MASTER CYLINDER.
This can be done by taking some rubber hose and putting it from the holes for the lines, back into he reservoir on the new master cylinder. Make sure the new master cylinder is full of fluid. Put the master cylinder in a bench vice, and press in the plunger repeatedly with a screwdriver until no more air bubbles come out.

Then put the new master cylinder back to the mounting surface, and reattach the lines. Bleed the entire brake system.

How to bleed brakes on 1997 Saturn


The brake system bleeding procedure differs for ABS and non-ABS vehicles. The following procedure pertains only to non-ABS vehicles. For details on bleeding ABS equipped vehicles, refer to the ABS procedures later in this section.

WARNING Make sure the master cylinder contains clean DOT 3 brake fluid at all times during the procedure.
  1. The master cylinder must be bled first if it is suspected of containing air. Bleed the master cylinder as follows:
    1. Position a container under the master cylinder to catch the brake fluid.
    2. Loosen the left front brake line (front upper port) at the master cylinder and allow the fluid to flow from the front port.
    3. Connect the line and tighten to 24 ft. lbs. (32 Nm).
    4. Have an assistant depress the brake pedal slowly one time and hold it down, while you loosen the front line to expel air from the master cylinder. Tighten the line, then release the brake pedal. Repeat until all air is removed from the master cylinder.
    5. Tighten the brake line to 24 ft. lbs. (32 Nm) when finished.
    6. Repeat these steps for the right front brake line (rear upper port) at the master cylinder.
WARNING Do not allow brake fluid to spill on or come in contact with the vehicle' finish, as it will remove the paint. In case of a spill, immediately flush the area with water.
  1. If a single line or fitting was the only hydraulic line disconnected, then only the caliper(s) or wheel cylinder(s) affected by that line must be bled. If the master cylinder required bleeding, then all calipers and wheel cylinders must be bled in the proper sequence:
    1. Right rear
    2. Left front
    3. Left rear
    4. Right front
  2. Bleed the individual calipers or wheel cylinders as follows:
    1. Place a suitable wrench over the bleeder screw and attach a clear plastic hose over the screw end.
    2. Submerge the other end in a transparent container of brake fluid.
    3. Loosen the bleed screw, then have an assistant apply the brake pedal slowly and hold it down. Close the bleed screw, then release the brake pedal. Repeat the sequence until all air is expelled from the caliper or cylinder.
    4. When finished, tighten the bleed screw to 97 inch lbs. (11 Nm) for the front, or 66 inch lbs. (7.5 Nm) for the rear.
  3. Check the pedal for a hard feeling with the engine not running. If the pedal is soft, repeat the bleeding procedure until a firm pedal is obtained.

My 1997 chevy 1500 z71 brakes suddenly going all the way to the floor. Checked brake fluid and it was low. Could be wheel cylinder? Master cylinder? or ?


well, check the brake lines for leakage after adding brake fluid to the full mark. If the brake pedal goes all the way to the floor, it's likely there is a leak somewhere after the master cylinder. If the pedal gets hard after adding fluid, and pumping it several times with the car off, then the master cylinder is still ok.

If air has gotten into the master cylinder, it may have to be bled out on a bench, or using a scanner if that's the way your vehicle is.

Bleeding the Brake System (ABS) Auto Bleed Procedure NOTE: Perform a manual bleeding procedure. If the brake pedal height and firmness results are not achieved, perform the auto bleed procedure below.
NOTE: Perform this procedure when replacing the brake pressure modulator valve or electro-hydraulic control unit.
  1. Perform the manual brake bleeding procedure. Refer to Bleeding the Brake System (non-ABS).
  2. Check the master cylinder fluid level often to prevent running the system dry.
  3. Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure (for Gas engines) once, or the Function Test (for Diesel engines) four times. Make sure to release the brake pedal between each test.
  4. Perform the manual bleed procedure again. This should remove the remaining air from the brake system.
  5. Bleed the system as many times as needed to obtain the appropriate feel of the brake pedal.

I put a new master cylinder on my car need help on how to bleed them please


The master cylinder should have been bled before installing it. The fittings and a small section of rubber hose should have came with it. If you have these fittings, you can still bleed it without removing the castercylinder. Install the fittings where brake lines come out and run the rubber hose into the "full" master cylinder and have someone pump the brakes slowly until all the air bubbles disappear. Reattach brake lines and the master cylinder should be all set. You will probably have to bleed brakes at each wheel
