It's time for the Scotty Kilmer Channel
if your cars losing brake fluid, you look inside and there's nothing, then
stay tuned because I'm going to show you how to find and fix brake fluid leaks
the first thing you want to do is get a flashlight, look on the inside of the
wheels to see if there's any fluid leaking inside, now in this case you can
see there's fluid leaking on the bottom of the tire and the drum is all wet, so
the cylinder is probably leaking inside here, so we'll pull the wheel off and
check, off it comes, and we'll pull off the drum and when we look inside
you see there's brake fluid all over the drums, because the wheel cylinders
leaking, wow that was sure an easy one to figure out, and of course what you need
now, is a new wheel cylinder, to put in place of the old one, it's not that big
of a job really, as you can see the back of this new wheel cylinder, there's one
bolt that holds a line you take off and two little bolts here, that hold it in
place, now the brake line that sends the fluid, you need this 10 millimeter flare
wrench, so you can get it on and take it off because a regular wrench won't fit,
now you can't see it, because it's on the inside, but this fits over the line and once
on the line, you give it a whack and that loosens the line up, when you're working
on cars, you often get used to feeling things with your hands and working
blindly, because you can't see in certain spots, you can only feel, then as you can
see on the back of the new one, there's two holes here and there little ten
millimeter bolts that you have to unbolt, so you get a little socket wrench and
feel them on the back and hit them and take them off too, then with your bare
hands, you can just take the bolts off, and tapping the wheel cylinder with a
little hammer, the cylinders now loose, but we'll have to take the spring off to
get enough clearance to get it off the car, you get a pair of little snip pliers and
grab the spring, now the cylinder comes right off and here's another trick
before you put the new cylinder on, take the bleeder valve off, that way it's
easier to feed the lines in, you just slide it in hole,
you get all the bolts them in, make sure they're nice and tight, and
don't forget to put the little bleeder valve in too, and of course pop the spring
back in the hole, and if you remember, brake fluid got all over stuff,
so it's a good idea to get a little brakes brake cleaner and clean all the
wet stuff off, now these brake shoes are pretty new, so they haven't been corroded
too badly, if they're all old and starting to come apart, then you'd put
new brake shoes on too, but these aren't very old, so we can just clean them up
then we slide the brake drum back on, give it a tap to get it on, and we need
to bleed the brakes out, you can use a giant screwdriver, stick it on the brake
pedal and jam it against the seat, then you hook a wrench up here, open it up, and
the air comes out, now once the air starts coming up, you tighten the bleeder
screw again, and repeat the process with a giant screwdriver four or five times
until nothing comes out but pure fluid, as you can see here now, fluid is leaking
on the bottom and the air is all gone and then of course stop the brake fluid back
up to the top, so it's full, so the next time you find your car losing brake
fluid, why not fix it yourself,
and remember if you've got any car questions visit the Scotty Kilmer
channel and I'll answer them as soon as I get back from my Shack!
