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

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.

How to Install Master cylinder in 2001 Bonneville?


The new master cylinder should have bench bleeding instructions provided in the box with it, it should come with some plastic fittings that screw into the holes that the lines attach into and some plastic tubing. You screw the fitting into the holes and attach the tubing to the fittings. Clamp the master cylinder in a vise and fill the reservoir with fluid, put the tubing into the reservoir and actuate the plunger until all of the air is worked out of the master cylinder.You will still need to bleed the entire brake system when you place the new master cylinder on the vehicle as air will be in the system from taking the lines off, this will just reduce the amount of air.

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.
