FAQs:
Will it fit my 4 wheel disc brakes?
The kit fits ANY TYPE or combination of drum or disc brakes,  The instructions specify what master cylinder to use.  Also fits any original 65-73 master cylinder.

What about Falcon and Ranchero?
Yes, with a bit of extra work it can be made to fit other applications, although not quite as easily as the 65-66.  Extra work means an extra piece must be welded to the
brake pedal in order to properly relocate the pedal pin.
60-63 Falcon must use original style master cylinder due to shock towers, or use Shelby style export brace with tandem master..
67-70 Mustang / Cougar - use the 67-70 Mustang/Cougar booster and pedal now offered by MustangSteve.

Will the tandem master cylinder clear the shock tower?   What about clearing an export brace?
Yes, it clears the tower by about 2 inches, and is not even close to the export brace.  (except on early Falcons and Comets, where the single piston master fits easily, but
the dual piston requires use of Shelby style export brace.)

Will it fit a 351W with Heddman headers?
Yes, it clears with no problems whatsoever.  You may have to remove the header to get the booster in place, but clears fine once bolted in.

Why will it not fit my car with original manual transmission?
The clutch actuation rod comes through the firewall in the exact spot where one of the booster studs must attach.  If you are using a T5 or Tremec tranny with a
MustangSteve cable actuated clutch, it will work fine.   Click
HERE for a superb retrofit cable clutch setup.
This conversion fits 1965-66 Mustangs with automatic transmissions
(will fit standard if you have cable or hydraulic clutch only)

Features found ONLY on the MustangSteve POWER BRAKE CONVERSION

Revised Pedal Ratio -  Less pedal travel required & modern car "feel",  (~ 2" travel w/ ft. disc, ~ 1" w/ 4 wheel discs)

Additional Firewall Bracing -  Welds to pedal support, eliminates firewall fatigue cracking around the booster mount area.

9" Diameter Booster -  Fox Mustang booster won't fade out under repeated stops like other conversions using off-brand or
imported booster.  Plus, you can always get replacement parts in the future.

Factory Fit and Appearance -  Fits better than the original 65-66 booster and works better, too.

Dual piston master cylinders fit with no clearance problems!  -  Original 65-66 boosters won't clear, but this kit will!

MustangSteve Booster Shown with 65-66 Mustang Manual Transmission Pedals,
Cable Clutch Conversion, optional 70 Mustang 1" Disc Brake Master Cylinder
     
POWER BRAKE KITS

Part #   PB - 2
65-66  Mustang    DO-IT-YOURSELF PARTS KIT  -  $37.00 (add $6.80 shipping)
(add $135 for Booster)  (shipping is $16.00 total for Option 2 with booster).
Includes a new redesigned
PEDAL PIN and the FIREWALL BRACKET plus the PLANS.
This kit also works on 65-66 F-100 Ford Pickup with minor firewall modifications.
Uses
Fox Mustang 4-cylinder booster or 80 Fairmont booster, or MustangSteve provided booster
of same design.  That way you can always find a replacement booster in the future.  
Use original FORD parts whenever possible, not those generic Chinese boosters that do not change the pedal ratio.

The power brake conversion bracket (65-66 Only) is a 10 ga. steel bracket that is welded to the front of the pedal support bracket (under
the dash).  It provides the support and correct bolt pattern for the power booster.  The pedal support assembly then bolts back in to its original
location, with 2 additional holes required in the firewall plus enlargement of the original center hole where the master cylinder fits.  It provides a
very nice, neat, factory looking booster installation, tight against the firewall, that can mount a dual piston master cylinder or you can use the
original Mustang master cylinder.

The pedal pin (65-66 Only) where the original master cylinder hooked up to the brake pedal must be replaced with a new design pin in a new
location on the pedal and welded into the pedal arm.  This weld must be done by a competent welder!  The new design pin, having a flange
added on the pin side of the pedal, allows the new pin to be welded from both sides of the pedal arm, which makes it virtually indestructible, and
stronger than the original Ford part.

The original pedal-mounted stop light switch is utilized, but it is best to change to a 70 Mustang
power brake stop light switch so the lighter pedal
pressure will still trip the switch under light braking.  Pedal height is slightly lowered, like a factory power brake car would have.  (Remember, it
takes less travel to actuate the power brakes due to the revised pedal ratio, and the lower pedal makes for a more comfortable driving position).  
Two metal brake lines must be fabricated to reach from the master cylinder to the proportioning valve or to tie into the existing lines.

I refuse to sacrifice functionality for ease of installation.  With my parts, you might complain the day you install them because it
was a bit of work, but you will enjoy the superior performance from now on.

With a lot of the aftermarket stuff designed to “bolt on”, you will enjoy one day of easy installation but then complain about the
lack of performance from now on.

Mustangs.

making it a bit easier to operate the brakes.
Not powerful enough for disc brakes.
$88.00 plus shipping
Includes:
  • 7" booster
  • Mounting brackets
  • Adjustable pedal rod
  • PB-6.3 master cyl.
