How To Use Mityvac Brake Bleeder

I only took a couple pictures of this process. For more pictures check out Cosmic's splendid how-to using a Motive ability bleeder. The procedure is very similar and the Motive is superior, but a MityVac is cheaper and still works O.K.

My cheapie method:

Plainly this tin can be washed with wheels on, but information technology'd involve more gymnastics. Putting it up on jackstands and removing the wheels makes life easier.

Employ turkey baster from a dollar store to remove as much old restriction fluid from the brake fluid reservoir. Use your wife'due south good OXO turkey baster at your own risk

:

Fill the reservior with your choice of brake fluid. Equally Cosmic used, I used ATE super blue brake fluid, from tdiparts.com. This style, you lot can tell when you're getting new fluid when you see the amber color change to bluish. Not necessary, but helpful. Otherwise use regular brake fluid and just draw through fluid until the older, darker fluid is gone and you're getting lighter, amber colored new fluid. Use fluid from a new, sealed container. Restriction fluid is hydroscopic (I think that's the word), which means it absorbs h2o. The reason y'all demand to change the fluid every couple of years is that the fluid in your car picks up moisture and can rust brake components from the inside. So don't use restriction fluid that'southward been sitting around in an unsealed container.

The MityVac comes with a diversity of attachments and a Cracking instruction manual. Hook the components upwardly every bit you come across here (new Balo right front brake shown...oooh, shiny...)

With a few squeezes of the handle, the MityVac forms a vacuum in the container. Open the bleeder valve 1/four to 1/2 of a turn, and brake fluid will start flowing. Cosmic's pictures of this are great.

Using the MityVac you lot will see a pocket-sized stream of tiny bubbling in the hose forth with the fluid. This is not air from your restriction system, but rather a small amount of air being drawn in around the threads of the bleeder screw. If you like, you can wrap some Teflon plumbing tape around the threads of the bleeder spiral to reduce these bubbles. The MityVac'due south manual said the trivial stream of bubbles was O.1000. and normal. I got the bubbling, and my brakes accept performed perfectly since doing this chore. This is the main difference between the two methods: with the Motive you are pressurizing the restriction fluid reservoir and forcing fluid through the organization; with the MityVac you're applying a vacuum to the bleeder spiral and 'sucking' the fluid through, which introduces the bubbling.

The MityVac manual says to offset with the brake CLOSEST to the primary cylinder, pregnant the left front. Then keep to the right front, left rear, then right rear, topping off your restriction fluid reservoir between bleeding each brake.

I think I paid $35 for my MityVac at a local WalMart type of shop. I've also seen them at the usual auto parts stores.

For an additional good use of a MityVac, check out the video clip of MOGolf doing a fuel filter change. The MityVac is handy for cartoon diesel fuel into the new fuel filter:
