    Is there any way to flush brake fluid without using a partner?
    I want to change my brake fluid. However, I don’t have a partner to help me. Most manuels say i need a partner to pump the brakes.

    • ANSWER:
      this can very easily be accomplished by simply gravity bleeding the system. start with the left front wheel and open the bleeder also take the lid off of the master cylinder, the fluid will drain out, just make sure to keep the master cylinder full, when the fluid from the left front caliper appears to be new clear fluid , close the bleeder and do the same thing on the right front caliper,, repeat on left rear caliper or wheel cylinder and finally right rear, very easy

    Brake fluid flush procedure?
    Can someone explain to me the steps to flush the brake fluid for a 2003 nissan sentra? I’ve looked online and different places show different methods. Some say just let gravity pull the fluid out and some say pump the brake pedal.

    • ANSWER:
      Remove the dirty brake fluid from the master cylinder reservoir with an oil pump or turkey baster then fill it back up with new fluid. Close the lid and have a friend get in the driver seat and pump the brakes a few times slowly until the pedal gets stiff. Now, go to the left, front brake caliper and open the bleeder screw and at the same time have your friend push down on the pedal, once the pedal is all the way down, close the bleeder screw. It’s important that the brake pedal stays all the way down until you have closed the bleeder screw. Repeat this procedure until the fluid looks clean (should take about 3-5 times).
      *IMPORTANT* Check the brake fluid reservoir every 3-4 times you open and close the bleeder valves to make sure it doesn’t run dry and add new fluid as needed.

    hard brake pedal while brake fluid flush?
    i was attempting to flush out the brake fluid on my 2005 honda civic lx. i pumped the pedal a couple of times, then it became rock hard. do i have to turn the engine on while bleeding/flushing the brakes?

    • ANSWER:

    What’s the normal feel of the brake after flushing the brake fluid + is brake fluid corrosive?
    I just flushed the brake fluid. The last time I did it, the brake pedal got progressively stiffer if I kept pumping it. This time, it feels normal but does not get progressively stiffer. Does that mean there’s air in the system (or air the last time when the brake felt different)? Question 2: If there’s a little air in the system, can it eventually dissipate or get pushed out to the brake pads? Question 3: I know brake fluid eats paint. How about rubber on the tires? My guess is not because the brake lines might be rubber.
    Thanks erikf150…The pedal does not fall to the floor. It is not soft. It is normal feeling. However, it does not get really hard like the last time. Does this mean there’s a liittle air in the system?

    • ANSWER:
      1) There was a problem (probably not air but loose self-adjusters on the rear) the previous time. You are good this time.

      2) Air doesn’t go away, it has to be bled out. But your description is of a system without air in it.

      3) Brake fluid is not corrosive, it’s just paint that doesn’t like it. Unfortunately it is a very big fire hazard. Rags wet with brake fluid and tossed into a pile can spontaneously combust. In fact, a fire investigator’s textbook I read said brake fluid is a favorite of arsonists – mixed with another common chemical (firebugs were hoping I would say which!) it is used as a delayed ignition source. I put my contaminated rags in a zip-lock bag and squoosh most of the air out before throwing it in the trash.

      One more thing – you may as well discard the unused fluid (check with your waste disposal people for how to do it, although it can be poured onto soil… it is biodegradable). Now that the can is open it will absorb moisture. I thought I could avoid that by really tightening the cap, but last winter I picked up a can of brake fluid and found ice pellets rattling around in the bottom.

    Replaced master cylinder, now NO brake pressure, what’s wrong?
    I own a 1993 Pontiac Grand Prix.

    My brakes were weak and a professional inspection diagnosed the problem as master cylinder failure.

    I bought one from autozone and took it to a shop, who put in the part and did a brake fluid flush and replacement, but now there is NO brake pressure at all, and they are telling me I might need to, replace the ABS pump… but I can’t see how I would not have regular brakes if the ABS wasn’t working- especially because the brakes were working a little before and not at all now.

    What could be wrong that the shop isn’t noticing.

    Thanks for your help!

    • ANSWER:
      is the brake fluid going low? if its not never rule out defective parts i bought a “new” master cylinder from autozone and it turns out that the part was messed up i thought it was something else like the abs but it wasnt try taking the car to someone else to get a second opinion.
