Brake master bench bleed?

Brakes are a pretty simple system. Everyone who works on their car should familiarize themselves with brake systems. They are important!

Now brakes I can do, and replacing them etc... However.. Instead of texting someone and asking I figure it better be on the forum for people to see.

On my other cars with no brake booster. The rod from the master goes into the car. And when you install it. You put fluid in it before hand and run the rod thru a few times to bench bleed it and get fluid down inside. However... On a car with a brake booster, there is no rod.

My question is... Do I need to bench bleed a master that goes on a boosted system? If so how?

I figure with it being attached to the booster, I would lay some plastic under it on the car to protect the paint. Install it without installing the lines, drop some fluid in there and hit the brake pedal a few times... Once it got some in the master down inside. i would attach the lines, then bleed properly..

Is that the right way, or is there a different way, or what? Lets hear it...

Yes.

Stick a screw driver in the end and perform exact same procedure.


You can bench it on the car-but that is more hassle.
Plus you have to buy a friend some beer to watch you do this.
Easier, by far, to just do it normally.

Put it in the vice, attach hoses, bleed it. Bolt it.

I see what you did thar.

So should I just install some bleeder valves where the lines normally attach? Then run little hoses on the tips of those back to the res, and bleed till no air comes out?

Si.



Normally, the masters I get have the attachments with them.

Was it your master cylinder leaking on the car you were talking aboot last night?
