In this video we show how to convert your 1965-1966 Mustang with Non-Power Drum Brakes from a single bowl brake master cylinder to a modern, safer dual bowl without any extensive line bending or modifications. This is a very popular upgrade, with tremendous safety benefits.
Installation is a little extensive, you need to either bench bleed the master cylinder before installing, or bleed the brakes after installation. Altogether the Dual Bowl Conversion Kit can be installed in your garage or driveway in about an hour.

Super helpful video once again, appreciate the step by step as a newbie. Worked perfect on my 65' convertible although the lines were reversed and a bit challenging to bend into the right places.

[@lewisvenecia2580]

This worked perfect on my 65 mustang , hardest part for me was loosening the brake lines from the distribution block other than that the brake lines were correct just had to do a little adjusting to line them up.

[@frankgrier4061]

I changed out my single bowl master cylinder today for a 67 Mustang dual bowl. I followed the instructions in the CJ Pony KZbin and it was a perfect guide. Thank you! Now if they can help with my aches and pains that came with the swap out. Advil assistance needed for this 66 year old for sure!

[@cjponyparts]

Wish we could help with that part!

[@trailervert]

That was a fun watch, thanks for the upload.

[@crazyhumpy]

Awesome! Just bought a '65 and was wondering how to do this! Thanks for the video!

[@Barngodess]

Your videos are immensle helpful to us, restoring our 65 6 cylinder Mustang. We buy our parts from CJ Pony ad well.

[@cjponyparts]

That is awesome! Thank You

[@ronschlorff7089]

Bill, thanks. I have 64 comet and 64 ranchero so these installation vids you do help a lot since they are "cousins" to the mustang!!

[@brandonfleetwood4201]

My 64 1/3 has two wires off the master cylinder do you have this problem on the comet or ranchero

[@ronschlorff7089]

I checked them and must say that both were built by others but the Ranchero does have two wires out of it and the car has drum brakes, the Comet has disk brakes in front and I could not see any wires, I checked my 67 Cyclone too and it has power disc brakes and did not have any wires out of the master cylinder but may out of the booster which is not visible. I don't know that it is a "problem", may be for lights or sensors, and all cars stop fine, but as I said I did not install them myself. Good luck with your car. : )@@brandonfleetwood4201

[@ScroatBagGarage]

Those two wires are the same as the 64.5 mustang, they are from a pressure switch on the M/C that activates your brake lights.

[@ronschlorff7089]

@@ScroatBagGarage thanks for that info! :)

[@sarangmarong8615]

Installing master Cylinder on my 65. Noticed that my lines were opposite, black threaded portion was rear brake line that requires the included adapter. Initially it was a head scratcher but it was easy to figure out as one of the ports is large enough than the other.

[@grumerguy]

66 mustang here. I did this conversion and what's not said here is if you have to use an extra fitting, which I did, it changes the fitment of the provided line (the line that operates the front brakes) and this becomes a much more difficult installation. That preshaped line has to be reconfigured to fit and without a tubing bender, you may well be out of luck. I do have a tubing bender and I wonder if it might have been easier to just make another line to fit. A good conversion, though, and I'm happy with the results.

[@musicalchris559]

Kascus - You could mount the brake light pressure switch in the distribution block instead of using the plug. Otherwise you would have to convert it to a 67 pedal switch.

[@mikeCkool]

I have a 62 comet.. Any ideas how I might be able to upgrade and install a brake booster

[@tnblly24203]

He made getting that clip off the brake push rod look easy. I haven't gotten it off yet.

[@Palacios29]

hey , I got a 66 ford ranchero ,definitely I need to change the master cyl, do they both use the same exact mas,cyl ?

[@jimreilly2156]

I am converting from front drum to disc brakes and single bowl to double bowl master cylinder. I noticed the double bowl just bolts tp the OEM distribution box, with no new lines needed for the rear brakes? Am I correct in this?

[@lhx17]

I can't find that style distribution block on your site, do you sell it? All I can find is the front disc brake block, I have all 4 drum.

[@vaioskaliakoudas6388]

Can I keep the stock single-bowl master cylinder and convert 'em to 4-whell power disc brakes or will they not work properly?

[@larryplummer7453]

doe's it matter witch bowl on the master goe's to the front or back becose i put the front bow on the master to the front brakes and back bowl to back brakes, but have not drove car yet.

[@SinisterJr]

4:27 definitely happened to me when i removed mine xD. I was so happy lol. But any idea how long it would take for a part like this to go back in stock?

[@eugeneslusher3793]

Did you a proportioning valve for this dual bowl upgrade? Some people use them and some don’t.

[@rodneymashburn7233]

I have 66 mustang 289 with 3speed manual transmission with the z bar close to the master cylinder will I have trouble converting to the duel master cylinder?

[@Chasepalmer1885]

Does this kit fit the 62-63 fairlane and meteors?

[@marklengenfelder9878]

I have a brake switch on my master cly is there a conversion for under the dash

[@Parched0001]

With this work with an aftermarket front disc brake conversion?

[@brandonfleetwood4201]

I ordered this for my 64 1/2 but my brake lights seem to work off the master cylinder not the brake pedal what do I do !!!! 😊

[@arcorob]

Bill this may be a silly question but since this is for a 65-66, why don't they just supply the correct length pushrod? I cant imagine that they used a variety of rods on the single bowl ...thoughts ?

[@michaelhelton2394]

can you say CHINA

[@uvgotredonu]

So theres nothing stopping the brake pedal from being pulled up and slipping the pushrod out of the MC? Doing this on a 69

[@halo3ownd]

didn't know bill was that funny, i almost died at 4:15

[@Zerogivengarage]

+halo3ownd Everyone asks how to get the pushrod out so we finally do a video to show you......and it falls out. Can't script this stuff

[@snake_eyes_garage]

I appreciated the bandaid on the hand... real life. 🙂

[@sonnym9954]

Amateur here. I'm converting my front drums to discs on my 64 Ranchero. I purchased a conversion kit that included a double chamber master cylinder attached to a vacuum power booster. The problem is that there is no space because the master cylinder hits the shock tower. Would it be prudent to just remove the power booster? As is, I'm already upgrading from a single chamber to a double chamber master cylinder so I believe it to be a step up. Please help

[@jeffkeith637]

Too easy. OK, I want to install a remote vacuum brake servo now, to keep the engine bay uncluttered. Do you have a kit for that? Thanks.

[@johnnyreyes5528]

How long to bleed , ive been pushing with a screwdriver and still have lots of air

[@alejandrorellana350]

I need a video for manual transmision . Can you help me?

[@SaffronInclinations]

I was surprised to see that the front brake lines hook up to the rear port on the new master cylinder. Is this because the front brakes need to be applied first?

[@classicstangbrn8964]

Hey Bill 65 Mustangs don't use clips to hold the rod in the mc, there is a pedal stop on the pedal hanger, 66s do not so they do have a clip in the ms, so yours is not broken.

[@GeorgeBonez]

Do you sell this kit for a 1964 Ford Fairlane? Hell I'll buy it right now if ya do!

[@MagaRickn]

I cringed when you set the master cylinder on the fender cover. Might want to point out that brake fluid removes paint! ;) And a back up wrench on the distribution block would make it safer and easier to remove the brake line. Good video.

[@sarangmarong8615]

how or where along my rear line would I add a proportioning valve, at line from the master cylinder?

[@Zerogivengarage]

+Sarang Marong We typically add them on the passenger side of the car on the cross over line that goes across the firewall and then back to the rear brakes.

[@2182ahmad]

I have a 64.5 it came with a inline 6. I put 5.0 motor in it now. I'm getting ready to switch out the master brake cylinder. Do you know if the new lines that come with this upgrade fit the 64.5 brake lines. They are the original lines.

[@brandonfleetwood4201]

My 64.5 has the brake light switch attached to the brake master cylinder I ordered this conversion to dual bowl to be safer but now I’m just confused!!!

[@mustangmaxford1965]

Why is there no place on the master cylinder for a brake light pressure switch? (64.5)

[@robertanderson5339]

If I upgrade my 66 mustang to dual bowl now, can I reuse it later when I convert to power brakes, and then later when I convert to discs?

[@robertanderson5339]

Will wheel size matter? I plan to upgrade from 14" to 15".

[@the15car]

Great video, very helpful. Just wonder why all car repair videos have to blare the cliche 'rad' guitar jams.

[@cjponyparts]

We have to have some kind of music or it seems very slow. This is an older video, the music we use now is much mellower and blends better.

[@the15car]

@@cjponyparts Thank you for the response. Still a very helpful video and appreciate that you do this.

Hi, i have a 6 cyl 68 mustang, working in a v8 swap, have installed a 8.8 rear end of a explorer, have 4 disc brakes, what kit do you recommend to fit my setup? Looking for a MAster cyl and booster for manual t5 transmission.

[@cjponyparts]

Are you using the original style Z bar clutch linkage or a cable conversion?

[@mowerman97]

I already have a dual bowl master cylinder. I would like to buy just the conversion lines as well as the distribution block. I couldn't find them on your website.

[@cjponyparts]

Benjamin Slaby We have the lines and the distribution block you need here: www.cjponyparts.com/mustang-brake-hoses-lines/c/60030040/ and www.cjponyparts.com/mustang-brake-proportioning-valves-distribution-blocks/c/60030150/. I can't give you specific part numbers, because it varies whether you have disc or drum brakes.

[@zlegolas14]

Do you sell distribution blocks, and proportioning valves for 1968 mustangs with 4 wheel drum brakes?

[@cjponyparts]

Zach Conley Yes, they'll be in these two categories: www.cjponyparts.com/mustang-brake-hoses-lines/c/60030040/ and www.cjponyparts.com/mustang-brake-proportioning-valves-distribution-blocks/c/60030150/.

[@hyder408]

on my 64 1/2, where does the electric switch get located to on the new master cylinder?

[@beeepizzle]

Do you lose any fluid when you remove the blue plastic caps (installed during bench bleeding) to connect the brake lines? If so, doesn't that render the bench bleeding useless?

[@doodlecaboodle9298]

No, it doesn’t let air back in

[@MCgangsta11]

@@doodlecaboodle9298 but will the fluid leak?

[@guyfaulkner3000]

Well your conversation kit for mustang fit a 1962 Ford Galaxie ???

[@wilburburnside9623]

Yup , just check that pushrod length . 63 Country Squire

[@andrewproffer2867]

Will the same process be used in a 1965 with a 3 speed on the floor?

[@thecoltster1]

yeah probably

[@christianlundmand7132]

The thread on the replacement tube for the front brake screw is wrong on the distributor end; it is too small. I have the original distributor block and was mounted with tubes from CJ Classics (which had the correct size).

[@crypto_11]

Why if ur 65 had a single master cylinder why it had the connections& adapter for front & rear ?

[@rs2543]

If I’m doing a full restore job do I need to bleed the brake lines or can I just disassemble and let it pour out?

[@cjponyparts]

For a full restore you can drain anyway you want to. I usually remove the MC and use air to blow out the lines.

[@rs2543]

CJ Pony Parts thanks!

[@mc-seven-e3101]

What breake fluid does a 302 1966 Mustang need

I have a 64.5, how would I incorporate the brake light pressure switch?

Thank you for the video saved me about 1200 from a shop that wanted to do all new brake lines

[@cloud8746]

Would these parts be compatible with a 1964 Ford Galaxie?

[@Zerogivengarage]

+cloud8746 I can't say, never tried but I would think they are similar.

[@Palacios29]

I would say yes ,64 to 66 ranchero ,galaxy ,mustang, are the same

[@mustangmaxford1965]

Just put one on a 64.5. There is on where on the master cylinder for the brake light pressure switch. Also, a brake light switch won’t fit on the 64.5 brake pedal. Hopefully I can rig the pressure switch on the plugged spot on the distribution block.

[@geovannyespinoza8519]

so this will make stopping the car better? even tho it still has drum brakes?

[@sjem618]

No it wont, it will make your braking system much more safe. If you have single bowl master cylinder and there is one leak in your breaking system, you will lose all brakes. If you have a dual bowl master cylinder and there is one leak, you will still have half of your breaking system. Might save your life!

[@geovannyespinoza8519]

thanks for the info! I appreciate it

[@svocobra]

The piece at 8:28, it's called a "union?"

[@bradleypeterson6202]

What is the cost

[@christianlundmand7132]

The blue plugs were not provided with my kit 😒

[@benstan4978]

Same with mine. But I think it should still be ok. I hear the supplies lines need an adapter or something after reading reviews on the site

[@raymondramirez2065]

Good video. Music was 100% unnecessary though.

[@2pink1stink]

Well this definitely doesn't work for single line vehicles older than this. This conversion only works assuming front and rear are on separate line already.

[@jsl5570]

WARNING The supplied brake lines are for a 1965 - NOT a 1966. They are different sizes and CJ apparently doesn't want to stock the correct item. They do the same thing with the heater box seal kit, and other items I've gotten from them. I'm done with getting parts from them. They know the parts aren't exactly correct, but with some effort & additional parts running the end user can usually make them work. That's a bad way to treat customers, so I won't be their customer any longer.

[@stangrestorer6473]

The line kit has wrong size flare nut.. Original Front Port on the distribution is 1/4" and the nut supplied on the line is for 3/16".. this makes a good kit a bad one... not everybody can cut and flare lines... but the people this 'kit' is marketed to can use wrenches.. Get your supplier Classic Tube to get this right... easy fix... Your statement at the 7.42 mark is true but this a BIG Disappointment for the cost not that I have to spend more money to get it to work.... bummer

[@georgemcleod1965]

Great advice! Can you PLEASE get rid of the terrible background music??
