Automatic Transmission Bolt-In-Kit Pedal Support with Booster for 65-66 Mustang: Front Wheel Disc Brake Car

Exclusive Features of the MustangSteve 65-66 Mustang Power Brake Conversion:

1. Revised Pedal Ratio

• Less pedal travel is required, giving a modern car "feel" (~2" travel for front disc, ~1" for 4-wheel discs).

2. Additional Firewall Bracing

• Welds to the pedal support to prevent firewall fatigue and cracking around the booster mount area.

3. 9" Diameter Booster

• Uses a Fox Mustang booster that won’t fade under repeated stops like off-brand boosters. Replacement parts are also easily available.

4. Factory Fit & Appearance

• Fits better and works more effectively than the original '65-66 booster, ensuring both improved performance and appearance.

5. Power Brake Light Switch

• The new brake light switch eliminates contact with the steering column tube, so you don’t need to dent your steering column for proper operation.

6. Front Disc / Rear Drum Brake Master Cylinder

• Designed for front disc and rear drum brake systems.

7. Adjustable Proportioning Valve

• Allows for precise adjustment of brake balance between the front and rear axles.

8. Manual Transmission Swap Ready

• Perfect for those with automatic transmissions who plan to convert to a manual trans in the future. The kit includes a sealed bearing shaft and adjustable clutch pedal stop. Adding the CK165-P cable kit later completes the setup.

Frequently Asked Questions:

• Will it fit my 4-wheel disc brakes?
  No. This kit is specifically for a disc/drum setup.  See our MustangSteve kit for the disc/disc setup.

• Will it fit Falcon and Ranchero?
  With some additional work, it can fit.  For early Falcons (60-63), the original style master cylinder must be used due to shock tower constraints.

• Will it fit a 351W with Heddman headers?
  The kit clears short tube headers easily, although the header MAY need to be removed during installation.
