It might not be an air in the line problem, but we will check it just in case. Start at the right rear, farthest from the reservoir, fill reservoir, and keep it filled, pump up pedal and hold it, unlock bleeder, put hose on bleeder screw and catch the fluid in a can, tighten up, pump up peadal again, do this at least 5 times, check, reservoir, go to next rear wheel, do th esame thing, fill reservoir, with new fluid, the old stuff gets burned, by the time you get to the front, you shoul have a pedal, if not, you have a leak, or th e guy on the pedal can't hold his foot down an dit is sucking the air back in. Chek it out and see if you got it right, if you have done all that, in that order, you either need to do it again, because of the amount of air in there or you have a leak somewhere. Hope this helps.

1998 CHEVY BLAZER...REPLACE MASTER CYLINDER, BOTH REAR CALIPERS AND ROTORS AND EVEN SCANNED THE ABS SYSTEM....NO PEDAL...hELP!!!


Vic, Because you changed master cylinder air probably got into the ABS modulator. Air can be very difficult to remove from an ABS modulator assembly because of the solenoid valves, if no bleed screw on the modulator, you may need a pressure bleeder and a scan tool to cycle modulator to bleed trapped air. Check the attached links,instruction and guides, Good luck. "I hope this helped you out, if so let me know by pressing the helpful button.

How to disable ABS brakes on a 2011 honda pilot?


Hello,
You DO NOT need to disable the ABS in order to bleed the brake fluid from the system. Almost all of the time you usually bleed the brakes with the engine off anyways to get a "Hard" pedal. Even if you were to do it with the engine running it would not affect the bleeding procedure except the pedal will never pump up to being "Hard" and will give a false reading of still being "Soft" or going to the floor when in fact it may or may not be already OK. This is not the fault of the ABS system, just the running motor.
Good Luck!

Brake pedal soft


You still have air in the brake system and this becomes evident when the operation of the booster allows the pedal to do down as it is compressing the air in the lines more efficiently than what you can do with your foot. Try starting the bleeding procedure but undoing the lines at the master cylinder and priming the unit first to get the air out of both sides of the unit. Tighten the lines and with the help of a assistant start at the longest line first and work back to the shortest. Booster failure will result in no assistance or engine stopping from a massive vacuum leak when the valves are opened. The abs is just a motor driven pump that supplies pressure to the brake system when the wheel sensors come into operation otherwise the brake pedal pressure is operating through the ABS unit to the brakes. (An ABS is only there to keep the brake pressure constant as the sensor opens and closes a valve to stop the wheel skidding . If it is not working then pressure from the pedal may bleed back leaving you with no brakes.)

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.

Bench Bleed the M/C first, then do not let it run dry during system bleeding. Parts stores sell a kit that helps installed m/c bleeding.

Can not get a pedal, replaced master cylinder twice, bled everything, no pedal...can't seem to get fluid out of the 3 front ports on the master cylinder...could both master cylinders be defective, or am I...


Did you bleed the master cylinder before you put it in the vehicle?This usually makes it easier to bleed the entire brake system if this is done before you install the master cylinder.Other wise all you have done is put air in the brake system.The master cylinder kit usually comes with a bleeder kit.This is for bench bleeding the master.Hope this helps.Good luck.

1999 Chevy Tahoe- Soft Brake Pedal


Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.

04 Focus SVT- All brakes will bleed out except the right rear..??


Have somone help you as you bleed the brakes. Have them pump the pedal 3 times and hold the pedal down with constant pressure while you crack the bleed valve open to the problem caliper. Don't let them release the pedal until you have closed the bleeder valve. Continue this process until you have fluid coming out without air. Periodacillay check the master cylinder to be sure it remains full enough so as not to allow more air in because the resivouir ran to low during the bleeding process. If when you are done and the brake light continues to be on then you will need to bleed the proportioning valve until the system balances out on line pressure.
If this works can you please give me a rating??? Thank you.
