Hello All,
I'm trying to help a buddy with a new Master Cylinder for a 1970 Super Bee (440 motor + Power Disc brakes). I'll attach a photo of the current one.
When I was looking at a few places online, the Master Cylinders I found all have brake lines coming in the other side -- on the fenderwell side. This one has them coming in from the motor side.
Does anyone know why the difference in a 1970 B-Body? I also have seen some mention of 10" vs. 11" brakes being different. I don't have access to the car now, so can't check .. but would that mean a different Master Cylinder as well ??
Thanks for any pointers on this!!

I'd say that's an aftermarket one. a friend of mine had a '70 Charger with the same set up, bought from the original owner.It had the lines on the inner fender side, and the cover was held on with the PIA bolt.

Ok, Thanks for the info on that.
Actually, I'm just trying to track down which master cylinder will fit this -- the ones I'm seeing online all have fender-side brake lines. For some reason, this car has engine-side lines..
Also, I'm wondering whether the 10" vs. 11" brakes make a difference. I see different part #'s online for the Master Cylinder.
Thanks for any info on this!

thats the correct master cylinder and booster for a disc brake equipped B body WITHOUT a hemi .
FYI the cap should be BLACK also
I agree.
All 440 Superbirds I've ever seen have this configuration like your photo. In fact, that particular casting Bendix master cyl is getting harder to find as a rebuild. You may get something that interchanges and fits, but isn't correct looking.
Since you have already have the correct one, I would consider having your local parts store send that one sent out to be rebuilt. Certainly do not return it as a core.

Doug, my bird has that type of master but Alan Spry's has the one that the lines are one the fender side like a hemi. The lines appear to be correct and not bent to fit. I think Galen has stated that Superbirds cam with either. To answer the question asked, however, that is the correct setup show in the picture. They are very hard to find in the original Bendix core. I have been told that a new one is available that is correct appearing. It is a foreign made part and available at Napa(I think). Some one on the board works for a manufacter and he know about this new master cly.

Oh, Doug, you probably did not look very closely at Alan's bird. The last time you saw it was when we were at the St Louis show several years ago that was sponsored by the wing car club. They let us all on the oval track. Somehow you and Alan got side by side and wanted to see which bird was faster. You could take him out of the turn, but Alan's hemi could catch you at the end of the straights. I was holding on for dear life in Alan's passenger seat! I thought we we were going to smack the wall for sure. Funny, Alan has asked me several time to go to the Good Guys show at the Texas Motor Speedway. I am hesitant to go for some reason!

As an FYI Napa now reproduces that master cylinder. These are NEW castings that have a nice flat machined surface as well for the cap...no more leaks!
Although the bail that they supply is a bit larger than the original (I reused my correct one)

Wow! Thanks a lot 6T9 ! This really helps me out.
I noticed on the Napa site that if you have 11" rear brakes, it shows you a Master Cylinder with Fender side lines. Only if you select the 10" brakes can you get the engine side brake lines..
Does anyone know why this would be a different master cylinder?
And did having 11" rear drums mean that you generally had drums all the way around vs. 10" for a drum/disc setup?
Thanks !

Ok, thanks!
So, 11" Rear Drums implies a 4-wheel drum setup then?
And 10" Rear Drums would mean drums in rear and discs in front? I think this is the setup I'm dealing with..
Thanks!

Is the master cylinder with the lines on the engine-side w/disc brakes also good when you have N96 on a 383 car?
