How to Replace a Brake Hose : How to Bleed Car Brakes


In this clip, we’re going to talk about the
proper way to remove and replace worn front brake hoses on a 1991 Ford Explorer. In this
step, we’re going to talk about the proper way to bleed your brakes after you replace
your hydraulic hose. Bleeding the brakes requires two people unless you own special tools. I
have somebody in the vehicle who is going to help me bleeding the brakes. The method
that you use is you want to apply pressure, have the person assisting you hold the pedal,
open the bleeder, and close it, then instruct them to come up and down. Then you open it
and close it. I’ll demonstrate that for you now. Okay, what I’m going to do is instruct
my assistant in the car to go ahead and pump the brake pedal. Okay, go ahead and pump the
pedal up. Give it about four good pumps. Okay, hold it. Now, you’re going to want to keep
your face clear because we will get some air and some hydraulic fluid spurting out, right
there. Go ahead and close it. Go ahead and come up. Come down and hold it. Come up. Come down and hold it. You can see
all the air bubbles we’re getting out there. The reason why you have to bleed your brakes
is that air is compressible, and hydraulic fluid or liquid is not. If you were to go
and step on your brakes with the system full of air, what it will do is compress that air
instead of actually applying the caliper. You won’t have any brakes. So, you’ve got
to go ahead and get all the air out. The new hose you put on is full of air working with
the bleeder and the caliper, you’ve probably got some air inside of it as well. Go ahead
and down and hold it. Once you’ve got good, solid fluid like that, there’s no bubbles
coming out, you’re done. Go ahead and snug your bleeder up. That is the proper way to
bleed your brakes. You’re going to go ahead and repeat that procedure for all the other
wheels on the vehicle, and make sure to check your master cylinder periodically so you don’t
pump it empty before you’re done.

  1. Should slip a clear hose over bleeder screw and emerce other end in a can of clear brake fluid so there is no chance of air re-entering the system

  2. i disconnected the brake line or hose whatever u call it… so when i put it back and wanted to bleed out the car brakes nothing comes out i filled it up with brake fluid and still nothing whats wrong with it hit me back ASAP plz thank you

  3. It is allot less messy if you put a clear hose on the nipple on the bleeder screw, and put it into a bottle or something to catch the fluid.

  4. I have to replace a rear strut on a Corolla. But the brake line is attached to the strut bracket and no slot to slide it out. I have to break off the line and the bleed the brakes after I'm done with the strut. My question is do I have to bleed all four brake line or just the one I am breaking off?

  5. @TheSvtjim A clear piece of line makes it a lot easier to see if there is any air left in the system. Not to mention keepin the mess to a minimum. Brake fluid eats paint off anything it touches

  6. most of these expert village videos give bad advice and working practices,this guy obviously sees no problem in allowing brake fluid to contaminate his work shop floor!
    the trouble is people watch these idiots and think its the corrrect way.

  7. Definitly should Hook up a Clear Hose into the Bleeder Valve , and the other end in a container, filled with Required Brake Fluid for Two Reasons
    1) So Air Does not Re-Emerge
    2) Cleaner Work area, instead of Brake Fluid Pissing all Over the Place

  8. this might be a stupid question, but i have never bleed brakes before if i replace the back right brake hose do i have to bleed all 4 sides or can i just do the one that's being replaced?
