which valves?

[tparker]

OK, I am a little confused. Im getting ready to redo the brakes on the car and apparently there are several types of brass valves, and not totally sure which is which and what I actually need. I converted from 4 drums to front discs and the setup includes a proportion valve.

When I look on line there are
brake valve
Proportion valves
Metering valves
Distribution valves
some combo valves
Saftey valve (I think this is just part of another valve such as the proportioning valve)
and perhaps some i missed.

Can any one shed some light on these and what I actually need? Is the brake, metering and distribution valves the same things?

Thanks
Tom

What year is your car and what parts do you already have (new brake lines or used)?

'70 Challenger. Not sure how much of the existing lines I'm going to replace, but will probably do some. But I'm trying to figure out what types of these different brass blocks/valves I need. The new disc master cylinder/ booster comes with atleast a proportion valve. When I look online, I see several other types of blocks, as listed above. Not sure which I would need.

So, after looking on line it looks like basically a combo valve contains several other valves (proportion, metering, pressure switch). I assume my kit, which came with a proportion valve, is actually a combo valve and I should be good. I hope. Else I'll go fast and just won't stop. LOL

Why not just go with a stock front disc brake set up?  It's easy since all the parts are easy to find and it's been proven to work well.

That's what I would do also. It will look original and all the parts are available from places like Inline Tube and The Right Stuff. They will also have all the correct lines pre bent for an easy swap.

You can use aftermarket brakes with the stock disc line/valve set up. I'd change out all the lines as well, since brake fluid is hygroscopic and will draw water from the air and if you were to look inside those nearly 40 year old mild steel lines, there wouldn't be a doubt in your mind. I used SS lines from Inline and will never have to worry about corrosion inside or out again. Worth the money and effort with the bonus of knowing that you won't spend God knows how much time and money getting the car on the road, only to rear end that Hyundai one day when he jams on the brakes right in front of you and blow a line trying to stop! Just my

I bought a conversion kit. Not worried about keeping things 100% stock. It came with the proportion valve, but I wasn't sure if I needed other parts. It looks like I don't.

I guess I will change out the lines too. Makes sense. Don't want to plow into anything. LOL

   Time and money well spent Tom! Good decision that you'll never regret.
