  • Alright so that would be reverse bleeding the brakes right?

  • @buddydog166 Yes. By pushing the fluid in from the bottom it forces the air up through the line and out of the master cylinder. It may still take a few minutes of bleeding to get the brake lever firm.

  • My brakes worked fine untill I took out the part of the brake cable that goes in the master cylinder, a bunch of brake fluid came out and I put it back in and the brakes didn't work. So I bleeded the brakes and it still doesn't work

  • @buddydog166 Ok, that makes sense, When you took the brake line off you got a lot of air into the system. Once this happens it's really hard to get it out. Your best bet at this point would be to open the bleeder on the caliper and drain all the fluid out. From there use a large syringe like in the video and slowly force fluid in through the bleeder until the master cylinder is full. Now you should have a little feel at the lever and should be able to bleed the brakes. Hope this helps!

  • Help my breaks won't bleed and when I pull in the front break lever the brakes don't grab. And I tried putting brake fluid in and bleeding it constantly

  • @buddydog166

    If you are doing everything correctly and the brakes still don't work your master cylinder is probably worn out. You can buy a rebuild kit and rebuild it. It's fairly simple to do but once you have installed the kit you will have to reverse bleed it like I show in the video in order to get all the air out.

  • how often would u say this needs to be done, plz reply

  • this doesn't help me at all...

  • do you have to take off the reservoir cap while bleeding the front brake?

  • Hello, I just flushed both brakes exactly as you did and bled them. Here's my question, when you pump the brakes and open up the bleed screw, should the pedal lose it's firmness? And yes, I tightened the bleed screw back. I think I need to change the brake pads too, as I honestly don't notice a whole lot of difference.

  • Alright thanks man that helped alot.
