Easiest brake bleeding ever

[mrtexas]

Vacuum bleeding on my 36 with corvette MC. Auto refill kit. The old fluid was pretty rusty. No pumping.

Good on you for keeping up with maintenance. How old was that fluid?

Good job, hardly anybody does this and it is really important.

I have that same kit, its not cheap. I got a big discount on it because it had been on the auto part store's shelf collecting dust for years before I came in asking for one. We had them at work and once I retired I couldn't borrow one any more. They work great, especially for just suckng the old fluid out of the master cylinder. If nothing else do that every once in awhile.

The tool has a rubber fitting that fits tight over the bleeder fitting. Its a little deceptive because you still see bubbles coming down the clear hose but that is not because there is air in the system it's because a little air is drawn through the loosen threads on the bleeder. You just keep going until fluid the looks clean. I can see buy your bucket that took awhile to find the clear fluid. I'd almost say that was the original fluid except your car did not come with hydraulic brakes. It was time, probably 20-year's past the time to flush it. That is moisture and rust in the fluid. Even though you flushed it out the fluid will probably tun brown again before too long. Once that rust gets inside the system its impossible to get rid of it unless everything is rebuilt.

Every two-year's it should be flushed on a daily driven. Probably at least every few year's on a collector car that sits most of the time. It depends on how well the system is sealed.

I have a mityvac 7201, works great on brakes especially with the speed bleeders installed. That fluid in the last picture tells it all

Hey, is there a set of measuring spoons missing from the kitchen

Technically, all DOT 3 is synthetic. Looks/sounds better to add the word synthetic.

Looks good. Did you clean out the inside of the whole system so the new fluid doesn't look like the old in a week?

[VeryTangled]

This goes in. This comes out. Nice bit of mantanance. Repeat as frequently as not necessary.

FYI: I have a vacuum unit like these. Same brand but its just slightly different as its older. I was having problems bleeding my system with the vacuum unit this spring and I ended up buying a pump up pressure bleeder. Wow did that ever work great. No spillage and no bubbles after the fluid has filled the cylinder so you know its good to go. The cool thing is that you can purchase different screw-on MC caps for the newer cars. Only bad thing is that the large, flat MC adaptor I needed for my large Corvette MC could be hard to use in a tight location. Most people could probably get by with the smaller adaptor.
