Check and make sure there are no leaks, if no leaks are found and system was bleed real good!! then you might have a bad master cylinder, was this problem there before brake job ,if yes and you never had to add fluid then its a master cylinder,fi everything was good before brake job, then something went wrong. hope this helps good luck.

Was the pedal ok (not going to the floor) before the brake job? If it was, there is probably still air in the system. Did you bleed the brakes starting with the bleeder that is the greatest distance away from the master cylinder, and continue to the next greatest distance, and finish with the bleeder that is the closest to the master cyl? Hope this helps, if not let me know, I'll try to help further.

SOURCE: proper way to bleed brake lines and system

First check your level in the brake fluid reservoir. If full, then you will need to pull off one tire at a time to bleed the brakes. There will be a bleeder valve on each caliper. Open the valve and pump the brakes until hard and hold, to get air out of the system. Then close the valve. I usually use a clear tube attached to the valve so that I can make sure I got all the air out of the line. Once air is gone, do the other side. Make sure to keep brake fluid full in reservoir to prevent air from reentering the brake lines.

SOURCE: when bleeding brakes have good pedal with engine off. with engine running pedal goes almost to the floor what is wrong

can you here a hissing sound when you push the brake while its running? if so then you have a bad brake booster, need to replace it, the hissing is actually the vacuum that builds within the booster escaping thru the seal in the booster

I bleed the brakes the brake pedal is hard then start the engine the pedal goes to the floor and when you press the pedal bubbles in reservoir so please can you help me thank you from claire.


Hello Claire

Do you have a bleed kit that forces fluid in from the connector on the caliper up to the reservoir? The old way of pressing the pedal opening the valve, closing it and releasing the pedal no longer works with brakes that has ABS. You start with the furthest caliper from the reservoir and work round all four until you come to the closest one.

I have replaced 3 disc brake calipers on my 2001 pt cruiser. after bleeding all 4 brakes 3 times, I started the car and brake pedal goes to floor. is my brake booster shot?


Michael:

You must start bleeding the brakes at the wheel farthest from the master cylinder (usually the right rear), then the next farthest from the master cylinder, then the next, then the closest. If your master cylinder is at the left front of the car, start with the right rear, then the left rear, then the right front, then the left front. If you don't bleed the brakes in the correct order, you are just shifting the air in the lines from one line to another. Make sure that you close the bleeder before letting the brake pedal up, and the engine should not be running when you bleed the brakes... Make sure that the emergency brake is off. Make sure that the master cylinder does not run out of brake fluid at any time that you are bleeding the brakes.

I have a low brake pedal on 2003 toyota 4runner


Did you also change the brake pads? Add fluid to top of reservoir?

Was the brake pedal low before you changed the calipers or is this something that developed after you worked on the car? If it was there before the caliper change then it has nada to do with the work you did.

U might have a bad master cylinder.

How do i bleed new brake caliper


Press brake, let off. Open bleed screw until the fluid runs out with no bubbles. Tighten bleed screw. Press brake and hold. Open bleed screw until pedal goes to floor then close bleed screw with pedal pressed to floor.. Fluid should come out with no air bubbles when open. If they are present repeat the last part.

What are the proper steps to bleeding your brakes on a 1990 vw golf deisel


For left hand drive vehicles: (If the car does not have ABS system you do not need any diagnostic equipment!)

IMPORTANT NOTE: You need using diagnostic equipment connected to the data link connector of the car in order to bleed the ABS block. Follow instructions by scantool equipment for bleeding the ABS block.


1. This bleeding procedure requires two people. Remove the brake system reservoir cap, and fill up with new brake fluid until "MAX" level is reached.
2. Lift the car, or use a channel for access under vehicle.
3. Put the gearbox in "N" - Neutral position, or in "P" - Parking position for automatic transmission.
4. Start the engine and push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor.
5. Begin with the rear right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
6. Repeat steps no.#4 and no.#5 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

7. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
8. Continue with the rear left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
9. Repeat steps no.#7 and no.#8 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

10. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
11. Continue with the front right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
12. Repeat steps no.#10 and no.#11 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

13. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
14. Continue with the front left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
15. Repeat steps no.#13 and no.#14 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.
16. Now the brakes are bleeded. Check the brake fluid level in the reservoir. Fill up with new brake fluid until "MAX" level is reached. Put back the brake reservoir cap.
17. Test the car brake system. The brake pedal movement no more than 1/3 of total stroke until the floor, when brake pedal is applied. Maximum admissible is 1/2 of total stroke.

CHANGED ALL BRAKES NOW PEDAL GOES TO THE FLOOR CAN


If the pedal goes to the floor you may still have air in the system.I assume that the pedal was ok before you started and that you may have opened one or more of the bleed screws.
Check the fluid level at the master cylinder.It need to be at the proper level.
You will need to be positive that no air is in the system.If you are not familiar with brake bleeding do not attempt as you may cause more problems.
The use of a clear plastic hose that fits snugly over the bleed screws at the calipers and is immersed into a clear container may be helpfull to see if any air bubbles are present in the fluid.
A bleed kit may be obtained from an automotive supply store.

Brake pedal still goes to floor 2000 GMC Jimmy


It's very possible to be the master cylinder, the o-rings on the piston could be worn, letting the fluid seep back through instead of getting full pressure through the lines. Could also be the brake booster.
Try changing the master cylinder first, which is cheaper and easier, and see if there is a difference, you'll need to bleed the brakes again.
To check the booster,
With the engine off, pump the brakes until the pedal is hard, then hold pressure on the brake pedal and listen for air escaping, or the pedal goes slowly to the floor, Do that after the master cylinder has been changed, at least that will be eliminated.

Changed front brake pads. brake pedal goes to floor. no brakes


Something doesn't sound right, you shouldn't have to remove the brake line to install pads. Did you have to do this on both sides? Do the new pads and the old pads look the same? Did you get the caliper on crooked? Just recheck your work first before replacing more parts. When you install the caliper, You have to hook the pad on one side first before you slide it over the rotor.
