Dual Bowl Master Cylinder Conversion Kit with OE Metal Lines for 1965-1966 Mustang with Non-Power Drum Brakes.

This kit allows you to upgrade your single bowl brake master cylinder to a modern, safer dual bowl without any extensive line bending or modifications. Includes pre-bent lines and a fully remanufactured master cylinder.

Please Note: The original push rod from your single bowl master cylinder must be reused to provide the correct pedal height and drive for the new master cylinder. Do not use the one included with the dual bowl master cylinder.

Vehicle Fitment

This product will fit the following Mustang years:

Rated 5 out of 5 by from Well... Not as easy for me as it was for Bill Great upgrade... However, I found a few things not addressed in the video. 1. The old fittings on the distribution block are not easy to get off. Place a wrench behind the block so it does not move on you. It's pretty easy to pull it completely off. *I think this kit should include a new block. 2. The push-rod is just about never stuck to the point you need to hammer it out. If so, you have the wrong part on your car. These are held on by the boot. 3. Remove your wiring harness at the firewall before starting. You need the room to work. 4. Put some shop towels under your working area. You spent too much time cleaning things up already. ;)

Rated 5 out of 5 by from Dual Bowl Conversion kit I installed this kit this past weekend on my 65 Drum/Drum. Kit had everything I needed. Fit was decent (didn't need to bend the lines but did need to disconnect the existing rear line from the firewall to attach to new line from MC, then reattached the line to the firewall). Bench bled the MC, but took a while to blead the breaks with the help of my wife. Took 3 hours (had some issues removing input lane from distribution block). All in all, I'm happy with the kit and would recommend to others.

Rated 5 out of 5 by from works nicely on 1964 1/2 Great safety upgrade. Works on 64 1/2. I have seen lots of questions on how to hook up the pressure switch that activates the taillights. Just take the kit to NAPA, etc when you get it, along with your original screw-in switch that was previously mounted to your original master cylinder. They can provide the fittings that you need to place the pressure switch onto the brake lines. There will be enough wiggle room on the brake lines to do this easily. Mine works fine in-line on the rear brake line near the firewall. Also, despite what the CJ video says, I don't see how you can do this installation without bleeding your brakes afterwards. Expect to bleed your brakes which will only improve safety and performance.

Rated 4 out of 5 by from Great safety upgrade Bought this along with a bunch of other brake parts for a 1966 Mustang that had sat for 10 years. Kit is terrific, but with some minor issues. First, there are no instructions, but there is a video. The video is great, but I had to destroy the old master cylinder to get the pushrod out. Second, as others have said, the fitting to the front brakes on the distribution block was the wrong size. I was able to buy an adapter, but better yet, a brake parts house was able to put the right fitting on and then re-flare the pipe. Better fit and look.

Rated 3 out of 5 by from Nice kit Bought this kit to convert to a dual master cylinder. The front line has a 3/16 fitting to the distribution block but the block was 1/4 inch, needed to buy an adapter.

Rated 2 out of 5 by from poor fitment Be prepared to do the following when installing this dual master cyl kit on original 66 Coupe: 1. Purchase an adapter for the included flare fitting to the factory distribution block, cut and re-flare line. 2. Significantly re-bend both included lines for proper fitment.

Rated 4 out of 5 by from Worked Great! With a small caveat Installed the dual bowl on my 66 mustang replacing the original single bowl master cylinder. The original distribution box on my 66 has a 1/4 inch connectors and the kit only has 3/8's. I had to purchase a 1/4 plug and turn the distribution box around 180 degrees so that the 1/4 plug that used to be the main feed from the master cylinder faced the back of the firewall. After that everything connected fine and worked great, but I can no longer bolt down the distribution box to the engine compartment.

Rated 5 out of 5 by from Does what it says on the box Cylinder bolted up quick smart. The pipes in the kit were the right lenght but wrong shape. However as I have a jan 65 200cuin I gues that was to be expected. A dry cloth and some grunt fixed it (one had to be looped). I followed the video instructions and the bench bled the cylinder... The misus was rapt when she only had to pump the break once.

2 questions.....why don’t you hook of the rear brakes back to the block?  Also, if I eventually upgrade to front disk will I need to replace the dual bowl again since this kit says front drums?

Asked by: Ping10
I didn't replace the master cylinder.... Went from drum to 4 disk... Brakes work great. Why would the master cylinder need to be changed? Curious..

If I install this Dual Bowl Master Cylinder to replace the original Single Bowl with Booster, will I need a new Pushrod or anything else?

Asked by: Cobretti
This will only work on manual brakes, it will not replace the single bowl power master cylinder.
