MC brake choice

[jimbosride]

New fuel system is done now it's time to think about the brakes on the RR build. I going to go with non-power disc/ drum on the car and found this MC.

If I go with this I would not have to put an adjustable valve on the rears? and use a stock distribution block? Anyone go this route?

Thanks

That is a big bore for manual disc brakes. You will need a strong leg. The master cyl.has nothing to do with brake proportioning.

That unit is too big for a manual system. It would be fine for power brakes though.
Going over 1.03 for a manual brake setup means a lot more pedal effort than most people would like.

7/8 or 15/16 would be better…

Ok .... did not know or think about bore size. I went with a stock unit and disc brakes on my 65 and it works ok but the adjustable valve is leaking.
I did not want to go the power brake route but now I'm not sure.

The car is going back to mostly stock with some upgrades. No big horsepower or racing. I have had this car since 1982.

What would you guys do on this car for brakes ?

Keep the drum brakes!!

Keep the drum brakes!!

Well, if the car is not driven in heavy traffic or down hills, if he is always alone and never needs to stop fast two or three times in a two mile range.
Drums are fine for light duty driving but why limit yourself?
A basic 11" front disc setup like what came stock on 1973-76 A body cars, coupled with 10" rear drums and either a 15/16" manual master cylinder or a 1 1/16" master cylinder and stock vacuum booster work quite well.

Ordered new stock brake lines.

So this is what I'm thinking ?

Add disc brake kit up front.
Keep the stock rear drum brakes on rear.
Use a stock distribution block.
Power brake master cylinder unit.
Mount adjustable valve at the rear for the drums. ( I figure you only have to adjust it once or twice) ( easy to get at if it fails or leaks)

Leaving drums up front does not sound like a good option since the car is not a collector or hemi car. But the power unit sounds good so far.


Any suggestion on the power MC unit?


Here is what is on my 65 Dodge. No way to service it or swing a wrench to mess with it. I put it in when it was on the rotisserie.
