brake master cylinder

[muddyoldman]

has anyone found a cast alum. body with a plastic dual res. master cylinder that will fit a swepty? my 68 already has the steel dual res. master cyl. with the two bolts holding it to a flat plate and then the flat mounting plate has four studs on it to mount to the firewall. you would think there would be a master cyl. that would interchange.

I plan on using one similar to this but I believe it is cast iron, not aluminum. I have seen one Sweptline with a master cylinder similar to this one.

That is the master for Power Disc brakes used starting in 79 running through1989 it is cast aluminum new I can get them for $91.00, I don't stock it for few (right now) have power disc brakes, if you want it send email through @ easystreeetllcparts@gmail.com

This is the booster you need with the master cylinder to mount to your firewall:

Oh, I forgot you probably don't have front discs. I will so I can use a newer master cylinder.

I'm running a Raybestos two bolt aluminum master cylinder meant for a ~'85 Dodge B150 van. Sounds like you already have the 2 two 4 bolt adapter. No vacuum booster, no hydro boost; just my foot, the master cylinder, and 4 drums. Clean and simple, just how I like it. I think I paid like $35 from RockAuto.

[MountainMoparRobin]

Thats true this is the remanufactured one for $35

For pre-'69 trucks [100/200] with manual
trannys, there is a stand-off bracket that
is needed to clear the clutch master cylinder.

To keep things clear.....
[pre-'69 100/200 manual tranny trucks]
The power booster on pre-'69 100/200
trucks does not mount directly to the
firewall. There is a "stand-off" bracket
that is necessary to keep the booster
from interfering with the clutch master
cylinder. According to what "Muddyoldman"
states, the booster pictured in this thread
is "very close" to fitting his bracket.....
meaning.... it is not a direct bolt-on part....
for any who are looking for just that.....

Mine came to me with a dual-line master cylinder so I can't say what it's from. Here's some shots of all that stuff.

Looks like the stock set up to me.

Could be, I don't have any reason to believe it's been molested. I thought it unusual that the lines from the master are rubber hoses, and I have no idea if a dual reservoir is standard in '68.

I'll be getting a little more familiar with the brakes soon, the right rear is weeping onto the backing plate and has developed a hint of pull to the left when stabbing the brakes.

Dual reservoir masters were standard in '68. I had
that same set up with rubber hoses on a '68 W200.

My 67 W200 is also the dual reservoir master and has similar rubber hoses, but no power assist. I was never sure if the lines were factory since it had a brake line lock installed in it for wrecker service. From what I've read, the 67 was the start of the dual reservoir master cylinders, my 66 Satellite is a single pot, 65 W200 started as a dual pot and 67 W200 and 67 Barracuda are both dual pots.

My '67 W200 came the same way and it has been in the family since new. The only real changes made were since I owned it.
