Brakes go to floor i changed master,4 calipers,4 brake hoses, and all pads


Time to redo the bleeding of the system again...starting with the master cylinder...you do not have to remove the master to re-bleed it. disconnect both brake lines from the master, and start again by pushing pedal to floor, and rebleed each line at the master...this is critical to work properly...you mentioned new master cylinder, if remanufactured I would return it. As noted above, after confirming the master is fully bled...rebleed each caliper beginning with the rear, farthest away from the master...you must have "air" in the brake lines. Hope this helps.

Rear caliper on 2005 Ford F150 not releasing, replaced both rear calipers, now pedal goes to the floor - no brakes at all. What can/should i do?


Sounds like it still has some air in the system or a bad master cylinder. First try bleeding all air, there is definitely some air left in the lines and this is most probably causing the problem. Bled the lines at the bleeder screws on the calipers. ---------- There is air left in the brake line.Any time the brake system is opened to replace brake lines, caliper, pads etc etc.Mostly the air enters the system, and that air has to be completely bleed.Otherwise the same symptoms , what you are getting will be noticed.-------- Brakes can be bled manually, with a power bleeder, injector tool or vacuum bleeder.IIt does not make any difference which method you use as long as all the lines and components are flushed with enough fluid to remove any trapped air bubbles or air pockets.----
The most common bleeding procedure is to bleed the brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car or truck, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.--------- When the complete air is bleed from the line, the brake should be firm when car is on.In your case brake brake pedal is loose and goes almost to the floor when car is ON.This is due to Air in the line.Get the complete air bleed from brake line.------- This will help.Thanks.Helpmech

The brakes are soft after replacing brake pads and calipers


If you replaced the calipers and the brake pedal is still soft the most common issue is air in the system. Check master cylinder and fill if needed, make sure all lines to calipers are tight and no apparent leaks, have a helper pump the brake a few times and press down holding in the down position (to the floor). At that time loosen the bleeder screw on the caliper releasing the fluid and air in the lines. A rag is recommended to cover floor. Do this on all calipers that were replaced a few times one at a time untill all air bubbles are not present, a clean flow of fluid . Make sure to have x-tra brake fluid on hand and check the master cylinder periodically (fill if low) and proceed with the bleeding process. If you allow the master cylinder to go dry and **** air the process of bleeding the brakes will have to be started all over again, so keep master cylinder level full after a few cracks of the bleeder. best of sucess to you !

Just replaced rotors, calipers, caliper brackets, and pads. Bled all four wheels, starting with the farthest away from the master cylinder working my way to the closest. Brake pedal feels firm when car...


Bleed with the car running and make sure all the air is out. Now make sure there is no leak and the pad contact are adjusted without much gap so that the calipers hold on. make sure the servo assist is correct, if so and the master cylinder was set right , it must work. Please recheck all your work once again to trim up.

Install new brake pads and rotors all 4 wheels. Replaced front 2 calipers. Bled brakes. New clean fluid coming out. pedal is still soft and goes to floor. 200 Seebring.


Are you losing any Brake Fluid? Is it visible anywhere at the four wheels? Is it visible anywhere else?
The Master Cylinder may be defective. When you bled the Brakes did you maintain proper Brake Fluid Level in the Master Cylinder? If you didn't: and air entered into the Master Cylinder there maybe air within in the system in the Master Cylinder. You can bleed the Master Cylinder by removing the brake lines, adding more fluid, pumping the brakes, bleeding the air out of the system.
Are you losing Brake Fluid and can't find a noticeable leak? Then there is a good posibility that the rear seal in the Master Cylinder is leaking and the Fluid is going into the Brake Booster - which is the large wheel shaped drum located on the fire wall. In this case both the Brake Booster and the Master Cylinder will have to be removed and replaced. The Booster contains seals that Brake Fluid is very caustic to and will ruin these seals- causing future failures.
If no Brake Fluid is lost, no leak found: Check the Brake Booster Vacuum Advance. This should be connected to the outside of the Booster, attached to a hose, with the hose going to the engine. Check to see if this is working properly. Replace if needed.

Pistons in both front calipers stay out, both calipers replaced


You may have a leak in the booster or master cylinder. You can put a pressure tester on the system to test for leaks. It does sound like you have an air leak.
You can try to bleed the master cylinder, then slave cylinder, then brake lines.

Brakes to the floor(almost) 99 blazer


bleed the brake again. if the pedal goes to the floor with little resistance, then the master cylinder is your problem.
the shim is to depress the noise when you applied the brake. you can skip that, if the brake works without it.

Just replaced master cylinder on 1990 aerostar and bled the brakes, still the pedal goes to floor and i have no brakes


Did you bench bleed the master cyl. before installing it? then when you installed the new master, did you bleed all 4 points? If yes, then check all for points for leaking caliper/s and leaking wheel cylinder/s. If the van has ABS, check the valve body for a bleeder screw and see if air bleeds out of it. If you've checked everything twice and did everything right then your new master cyl. may be defective.

Bleed brakes but no pedal


Good! You bled the master cyl. before installation! The proper order of bleeding the lines, is to start with the wheel the greatest distance from the master cylinder. Then work your way to the next greatest distance, and last, the closest wheel. Make sure all air is removed from the lines before you proceed to the next wheel, and frequently check the master cyl. level, because, as I'm sure you know, if you **** in air at the master, you have to start all over again. I'm assuming you don't have a power bleeder, so with a helper do this with car running (make sure it's on safety stands and not going to fall on you!) Pump pedal 3 times, no need to mash the pedal into the floor, just 3 pumps 1/2 way down, hold 3rd pump at half way down level while bleeder is opened, when flow is about to stop at bleeder, close bleeder and repeat til no evidence of any air. Let me know how it goes and if you need any help.
