1969 Mustang disc brakes
« on: March 13, 2021, 06:01:40 PM »
Hi Guys about 10 years ago I installed hydro boost on my Mustang because there wasn't enough vacuum to run the brake booster. Fast forward 12 years I am putting in electric power steering because I'm tired of the sloppy steering and the clutter, I want to get rid of the power steering pump and hoses. What are you guys using for braking these days. I am considering putting in a vacuum booster and a electric vacuum pump.  What are the choices for manual disc brakes ? Opinions please of course I have a roller cam with a ton of overlap so the vacuum is no better now.

So, what is your vacuum? Have successfully used a vac. can for years now on my '70 Stang with great success with about 10.5 inches at idle. Can easily get 3+ heavy stops in short intervals w.o any loss of braking power.

I have manual brake wilwood master front stock discs and wilwwod discs in rear and stopping is ok not great I will be curious how yours comes out. I have tossed around the electric steering but didn’t want to cut up my column. My car isn’t all original or anything it’s just in my head I guess.

Using a Maverick manual disc brake MC and switched to a manual brake pedal and works great and low vacuum doesn't matter.  I went to one piece replacement front rotors since even the long ARP studs for the original two piece rotors were too short for the thick Draglites.

That's what I did.  I used the Maverick manual disc master cylinder.  I originally had 4 wheel power drums on my '67 Cougar.  I removed the power booster system and put '68 single piston discs from a '68 Cougar on the front along with the Maverick MC.  I kept the stock rear drums.   I really like it.  I can put any cam I want in it, plus it weighs less.

Does anyone have a part number for the manual disc master?  Rock auto calls out manual brakes doesn't specify disc/drum.

Running same Mav manual master + mid 70s single piston disks on my Falcon for the last 27 years or so.  Did the same swap on the 70 we had.  Racing or street, no problem stopping.

Maunal masters will have usually a 15/16" or little smaller bore.  I have old Wagner Brake catalogs at the house, can look up a part number this evening.

cool just have to find a manual brake pedal or move the master towards the pivot point from what it looks like.

I don't remember the part number, but I think it was for a 1974 Maverick.

A Granada M/C with 15/16" bore bolted right up to my 65 F100

Lines face towards fender

Used front disks from 74 F100 that came with a 1" bore M/C

Had to shorten the push rod a bit

Factory rear drums and will slow the Slick down great even on wet streets

Put up some catalog info on masters and misc in a separate thread to make locating easier later on.

Thanks for the info manual pedal and master on their way. Looks like Grenada is the same also. First thing is to get the steering done had a few things welded so now just to assemble and wire it.

Update on electric steering I must say I am pleased all the slop is gone. I am not so pleased with the manual disks pedal travel is a lot and needs lots of effort. It will do for this summer but I will need to do something better than the manual brake pedal and the Granada master cylinder.
