OK I have installed the new SS hard lines and the 4 wheel disc Cobra brake swap from Mustang Steve but I have run into a snag.
I bought and installed a Modern Driveline hydraulic clutch kit and now I cannot install my MBM (67 Mustang/Cougar) brake booster and universal disc/disc master cylinder because the booster is just a little too wide so it will not fit because of the clutch master cylinder now mounted on the firewall.
So now I have re-installed my original Bendix booster as the overall diameter is just that little bit smaller that it will mount perfectly next to the clutch master but now I cannot use my universal brake master cylinder because it wont fit between the booster and shock tower.
I need to now find a disc/disc master cylinder that is shorter to fit like the original 67 master was.
Anyone run into this or has installed the Cobra Swap 4 wheel disc kit as I need an idea for a replacement master cylinder???
You could do what I did, use an original style disc/drum master. This is what I did after a lot of research (They do not put Residual Pressure Valves (RPV’s) in new masters). Just make sure to keep the smaller drum side full as it will empty more quickly as the rear pads wear. Or (and this is my slick idea), drill a hole about halfway down in the wall between the cylinder front and rear chambers. This way the chambers share the reservoirs until they reach the level of the hole. This is how modern reservoirs work.
Probably not what you want to hear (use old stuff instead of what you bought for the purpose) but it works.
I ran into that same kind of issue when installing the SSBC front/power disc brake setup. Put the booster in, and went to do the master install, and couldn’t get it on the studs. What I ended up having to do was unbolt the booster enough to get it canted out away from the tower, install the master, then bolted the booster back up snug. Tight, but it fits. Have you tried that, just in case? Would hate for you to throw more money at it if unnecessary! (I’m sure you probably tried that, but just a suggestion…)
Yes I tried that too but still not enough clearance between the shock tower. I think I will probably try Bob’s idea and see how she works once it’s driving.
I have been told to use the 2000 V6 Mustang booster but aren’t the bowls slanted on a forward angle on them as the boosters point slightly upwards on the 2000 Mustang??
I would search the internet and Mustang Steve’s forum for info on this, I can’t recall exactly but there were multiple reservoir possibilities, one of which was tilted as you observe, one has a sender (and tilted), there might have been one that was less or not tilted. Look at Street or Track’s site too for clues (not suggesting buying there but it is another place that sells this sort of stuff).
Yes, even the OEM setup is tight. Getting the master out is just BARELY possible without loosening/moving anything else. You have to play with the pushrod to get it to stay in the booster, if it comes out at all it makes it impossible to remove the master. Also, FWIW, this area of my engine bay is a sore spot with me, the mess that got made there is impossible to properly detail/cleanup after the car is together. Between the OEM setup poor pedal problems I had initially and then the Cobra upgrade, the area looks like it has “been through a war”, does not meet my standards. I would like to pull the steering box and redetail it, but there is no way it will come out with the Z-bar, the full length headers, etc… At least it is not very visible. Guess if the brakes work well that is the main thing. The rest is somerthing that I have had to learn to live with.
Glad you found a workable solution.
BTW, did you drill a hole in the wall between the reservoirs? I would love to do this on mine but I am not taking the master out, reinstalling, bleeding, etc. just to accomplish that!
And yes Moe it is the Wilwood clutch master cylinder from the Modern Drivelines kit. The red cap is just temporary until I install the remote reservoir.
