1964.5-66 Mustang Hydraulic Clutch Master Kit .750 bore/Billet Reservoir



Fits:  1964.5-66 Mustang 


1964.5-66 Mustang, LF Series Hydraulic Clutch Master Kit 
(.750″ bore x 1.4″ stroke)

Modern Driveline Light Foot series Hydraulic Master cylinder clutch kit for 64.5-66 Mustang uses the stock clutch pedal.
Engineered to use the factory full pedal swing, for maximum leverage.
Provides you with a light pedal effort and full control of the clutch.
This translates to a drive you will love.  Unique to MDL is the clutch pedal linkage that moves the master cylinder to provide room for brake boosters of all types and most importantly driver control.
Gone are the days of having to engineer a kit from scratch only to leave you frustrated with the results.

The Type 3 master cylinder utilizes a .750″ small bore 1.4″ long stroke cylinder to provide the most common fluid volume requirements needed in today’s hydraulic slave cylinders.  

Couple this master cylinder kit with either MDL LF series external slave cylinder kit or Tilton Engineering internal hydraulic release bearing results in a complete hydraulic clutch solution ready to install.



  • 1964.5-66 Mustang

 LF (Light Foot) Series

  • Pedal linkage for light pedal effort 
  • Uses stock clutch pedal and rod hole (where possible) for ease of installation
  • Included anodized aluminum reservoir
  • Works with most internal and external slaves.

Common Hydraulic conversion problems

.The common approach was to use a 3/4″ or 7/8″ bore x 1″ stroke master cylinder connected to the pedal directly resulting in the following.

  • Improper pedal pressure and stroke the cylinder needed to be raised higher than the stock clutch rod linkage hole.

  • Interference issues on the firewall or pedal assembly.
  • Heavy pedal pressure or a very short stroke or both.

Revolutionary Design Linkage Design

The LF Series Hydraulic Clutch Master is a revolutionary design for retrofitting hydraulics into the classic cars

Modern Driveline solved these issues with innovative pedal linkage that matches pedal travel with a long stroke master cylinder for a reduced clutch pedal load.
The linkage allows for great design flexibility and greatly improved driver’s experience.
We offer the master cylinders in three different bore sizes to match the slave cylinder volume requirements.
In most cases, our .700″ bore with 1.4″ stroke is the perfect match for most slave cylinders on the market and all our LF series slaves, Tilton 6000 Series internal bearings.

Tech info

Certain brake boosters will not fit with our LF Series master cylinder kit due to their size and shape.

This kit works with OE Bendix or Midland 8″ booster. It will not work with (band clamp) brake booster and certain aftermarket 8″ and larger brake boosters.

The brake booster below due to its profile & mounted distance from the firewall will allow the Hydraulic Master to be mounted correctly.

  • The long-stroke, small bore master cylinder minimizes loading of the firewall and pedal effort. 
  • A firewall plate with mechanical linkage greatly reduces firewall load and pedal effort while providing design flexibility to use the stock clutch rod hole.  
  • The mechanical linkage design also allows the full stroke of the pedal to maximize clutch modulation while keeping the cylinder perpendicular to the firewall and providing mechanical advantage thus reducing the pedal pressure required to operate the clutch.

ALL MDL Hydraulic master kits come with
One-man Bleeder Kit to help make installation easy.
