1962 - 1971 Ford Fairlane and Torino owners rejoice! These applications have only 12" of room from the firewall to the factory shock tower, which means they are very limited to what will fit in there. The factory power brake arrangements for these cars ran an offset cantilever package that raised the vacuum booster up and over the shock tower to make it happen back in the day. We have built a few systems over the years that graft the hydraulic booster in place of the vacuum booster up and over the shock tower, though found it not to our liking for how obtrusive it was into the engine bay (big ol' mess sitting up on the driver's side of the engine compartment!), also finding a pedal ratio decrease occurring through the cantilever package that wasn't to our liking either. After 15 years of NOT being able to accommodate these applications (without use of the factory upward offset vacuum boost cantilever), we have accomplished a breakthrough design that brings the assembled length of the hydraulic brake booster and master cylinder in at a never before heard of
incredible 11 3/4" inches! (tape measure in images shows shorter still - casting variations being accounted for - nominal assembled observed length coming in at 11.6")
What makes this system special is that it is designed to bolt straight into the firewall, eliminating the up and over the shock tower cantilever. This now allows the entire system to tuck very neatly much lower down and out of the way between the firewall and the shock tower. It is as slender as the master cylinder on the engine side, so if you have a manual brake car, just visualize the package having the same profile on the engine side, just longer.
NEW SPECIAL ORDER MODEL # 3869
The brake assist unit itself hasn't been shortened up (6 3/8" from firewall to MC mounting flange) - it's the late model "micro master" design at 5 3/8" installed length that makes it happen. Do please note that this MC may look normal as bolted to the face of the brake unit, though it will most definitely not fit a typical vacuum booster or any hydraulic brake booster (proprietary mods required to make this micro MC interface with a hydraulic brake assist unit) - similar to the proprietary mods required mods required to accommodate our special order balance bar design debuted last year:

NOTE: Let's save some tech calls in advance: This new Fairlane / Torino or the balance bar system are designs that you could NOT replicate on your end in any type of bolt on format. There are highly specific proprietary designs at work here to make this happen. This particular MC bore size is 1", and has been proven to work with disc / disc and disc / drum braking systems. We do not have alternate MC bore sizes of this design currently available at this time. This system must be ordered as a combination of the brake assist unit with the master cylinder included - the only options at this time is the level of preparation (base / street prep / full show prep) and whether you want a power steering line set included with the order or not (meaning you cannot order in just the brake unit or master cylinder separately, as it is a matched / blueprinted set). We may be able to do a CNC machined billet aluminum firewall mounting plate as opposed to the steel plate shown for you as an upscale option - contact us for further details. Since the brake assist unit mounting nut protrudes out of the backside of the flat steel mounting plate to keep the installed length as short as possible, this will mean that you will have to clearance grind the round firewall MC pass through hole with a carbide burr on an air motor slightly to clear the brake assist unit mounting nut. And of course costs, right? The base model pricing for the brake unit / master cylinder package is $775. And YES - we may be able to incorporate this new super short micro MC design into other certain applications upon request where space is at a premium - contact us for further details.
