Drum to Disc Brake Conversion For My 1968 Mustang: Part 8

In this episode I do a manual drum brake to power disc brake conversion for my Mustang. I remove the original front drum brakes, install disc rotors and calipers, convert the original Mustang 4-lug bolt patter to 5-lug, and install a new set of wheels. I also add a power brake booster and install a disc brake master cylinder and Mustang disc brake pedal. After a few brake hard line replacements and a master cylinder bench bleed, I show how to bleed brakes using a Motive power bleeder.

I'll just stick to drum brakes for now. Thanks for showing though! 👍

[@MartinodePueblo]

Looking forward to the next one, man!

[@NightWrencher]

Looking great! Clean and concise work as always!

[@noboltsleftbehind]

Thank you sir

[@NightWrencher]

@@noboltsleftbehind side note: for setting the bearings I always go a little more than snug and let it go. Have never had one fail but maybe theres a reason to do it the regular way 🤷‍♂️

[@noboltsleftbehind]

@@NightWrencher I always seem to have to re-tighten after a few drives, so you might be onto something.

@@noboltsleftbehind i'm honestly so glad that you made this video cause i've been stuck on drilling the booster hole cause i really scared of screwing it up but this helped me a lot

[@noboltsleftbehind]

@@hdblooms5376 glad I could help!

Very nice👍

Thank you sir

I'm really enjoying your videos. Thanks for the tips. I am converting my drums to power discs x 4. It's been a pain for sure but worth it in the end. Funny coincidence, I also am doing engine stuff as well.

[@noboltsleftbehind]

Thanks man! Huge difference after the disc brake upgrade, absolutely worth it for sure. What kind of engine work have you got going on?

[@IronHorseGarage]

Can you please tell us what fitting you used on the rear of the proportiong valve to tie in to the rear brake line? We are having one hell of a time trying to get the proper fitting. We will probably end up cutting the end off and putting a 5/16" line fitting on it. Thanks for the video!

[@noboltsleftbehind]

I remember the fitting on the Mustang side being standard thread and on the Explorer axle side being metric. There's a thread size between the two that's coincidentally almost identical, I want to say it's a 3/16-24 line into the Explorer's 10mm t-fitting.

[@IronHorseGarage]

@noboltsleftbehind Thank you for the info. We ended up cutting the line, sliding the correct fitting on, and re-flaring it. We'll have a video up soon of our conversion.

You could get 02 back crown vic wheels btw if you want a cheap stocker that will fit. The 5 spoke ones that came on lx sports for example would look pretty damn good. Ranger/explorer wheels work as well. Later mustangs will but they have the wrong offset and you need spacers to use them. Just cheap rim options for ford.

[@noboltsleftbehind]

Thanks man, some solid advice.

[@jeffreyrigged]

@@noboltsleftbehind oh i forgot you can use 03 up crown vic or other panther platforms with spacers like the mustangs.

Looks like I bought almost the same kit for my 1968 Ford Fairlane. mine did not have the new brake lever or proportioning valve mounting plate, however had the factory size 8 inch power booster and booster bracket. I cannot seem to get a answer to my question maybe you can help. My 1968 came with all drums without power brakes. You could have ordered it from the factory with front power disc brakes. The factory disc brake option had larger brake lines in the front than rear. here's the question. to make this kit work do I need to buy the larger front disc brake lines OR is it a direct fit to the old stock drum brake lines ???? I would assume if it is a plug and play kit that the proportioning valve would be set up to work with the smaller lines. How did yours finale work out ? thanks

[@noboltsleftbehind]

That's a good question, I had to replace some of my factory lines because they were pretty old but I don't remember there being a problem with brake line sizes. I think I hay have used a brass fitting or two to adapt some of the threads. You of course would want to replace the prob valve since drum/disc proportioning and residual pressure would be different.

[@jaydavis7069]

Did the calipers fit without using spacers??????

[@noboltsleftbehind]

Yes, from what I remember the calipers fit right on

[@gregschmid7684]

No proportioning valve installed?

[@noboltsleftbehind]

It's there, it's built into that brass block I installed under the master cylinder.

[@piratedave3803]

You left us without a follow-up on the results? Did you like the conversation? How much improvement was this conversation? Take us for a test ride, please?

[@noboltsleftbehind]

You're right! Sorry I was moving pretty fast on this project, didn't get around to doing an in-depth review. Yes, huge improvement as you might expect with the power discs vs the manual drums. I'm actually quite impressed with this particular kit, I didn't realize it until I un boxed them but they're 4-piston calipers. Stops like a modern car now.

[@jeffreyrigged]

I wish you where closer to me id love to collab w you. Cali is a far drive from ky.

[@noboltsleftbehind]

For sure man, definitely a long drive, haha. but if you’re ever in the LA area let me know!

[@jeffreyrigged]

@noboltsleftbehind definitely will do. I've never been but the route 66 is a bucket lister.

[@robinbanaszak9596]

What brand is your conversion kit

[@noboltsleftbehind]

It's the Performance Online kit, part number WBKS6873
