    Brake Conversion

    Factory produced '75-'80 Granada/Monarch front disc brake spindles on a '65/'66 Mustang front suspension will have the potential to induce steering problems. This is because the '65/'66 Mustangs have a 2" narrower track width than the '75-'80 Granada. The steering arm angles are not the same...

    1966 6-cyl Brake Booster Question

    The universal 7" diameter boosters simply do not work well on early Mustangs. Any decent brake booster will need on the order of 18"-20" of vacuum to work at full potential. The best booster you can put on an early Mustang comes from the '87-'93 Fox Mustangs --either the 2.3L single...

    68 Base Model Braking Issues.

    Unless there is a blockage in one of the 3 ports of the primary side of the drum/drum pressure differential valve, I don't see that this would be the problem. All 3 ports of the primary side are common to each other. This means the pressure at all 3 ports would be equal. But, entertaining the...

    Will 'brake' For Beer.

    In a factory installation, the only Fords that will have a proportioning valve would be one that has discs front/drums rear. Proportioning is only one function of the combination valve. The other function of the combination valve is pressure differential sensing. These two functions of the...

    Disc Brake Conversion

    Your all drum brake car will have a pressure differential valve (just follow the lines from the MC and it will lead you to the valve). Other than distributing the brake fluid through it, for the front and rear brake circuits, it only has one function; to sense for a difference in brake pressure...

    Master Cylinder Question

    In it's OEM configuration (as produced from the factory), any MC in an early Mustang with drum brakes would have had a residual pressure valve (RPV) under the seat, in the MC port(s) supplying fluid to the drums. If you go to a parts supply place to buy a replacement MC, chances are great that...

    Brake Proportioning Valve

    If you have a stock combination valve (valve for discs front/drums rear), you do not want to add a separate, manually-adjustable proportioning valve in line to the rear brakes without first removing the proportioning valve, valve spring and valve seals from the original combination valve. If...

    External Tranny Cooler & Line Kit Reccomendation

    It's easier for me to just post a link to one of my previous posts, from eleswhere, than to try and post/restate the information & photos all over again: http://members.boardhost.com/MustangSteve/msg/1329770834.html

    Master Cylinder swap

    The valve illustration in the previous link is a Pressure Differential Valve. That particular valve is a for a Mustang with drum brakes at all four corners. If the Mustang had discs front/drums rear, there would be a an add-on proportioning valve in tandem with the pressure differential valve...

    Modern master cylinder in 1967 w/ 4 wheel disk

    The Fox booster could be adapted but if you already have a stock booster/pedal, my suggestion would be to turn your booster in for a core and get an exact replacement at the parts store. A parts store replacement would also come with a warranty.

    disc conversion on 1968 mustang

    The 4-piston K/H brake system is no more 'correct' for a '68-'73 Mustang than the '75-'80 Granda disc brake system would be. However, the Granada front disc brake setup is very close in design to the stock '68-'73 Mustang front discs, whereas the '65-'67 K/H front disc setup is nothing like the...

    should i up my gear ratio

    3,000 rpm's on the highway for more than 20 or 30 miles gets to be annoying, due to the decible level inside the car. Overdrive will make all the difference in the world and you can also run a low rear gear set without the high RPM penalty on the highway, so you get the best of both worlds...

    Disc Brake Conversion

    It's not a major issue of conflict. We are just having a grown folks conversation. We also have something in common. I also own a Mach 1 --an Azure Blue '03 model. I've owned it since new and it has been my daily mode of transportation for the past 7 years now. I've replaced the pads on it...

    Disc Brake Conversion

    F1's have great brakes and performance. The difference between an F1 and a Cobra or Viper is that an F1 is purely a race car and not a factory production model. The Cobra and Viper are production vehicles --one made by Ford the other by Dodge. The Dodge production vehicle has the 'superior'...

    Disc Brake Conversion

    After doing some research, I found that the Dodge Viper utilizes gigantic brakes with massive fixed calipers, both front and rear. The'03 SN95 SVT Cobra was the top-of-the-line performance offering from Ford with an MSRP of $37,845.00 dollars. The Viper would definitely fall under the...

    Disc Brake Conversion

    The Boss 429s used the same brake rotors as the other '68-'73 Mustangs with disc brakes, but the hubs were different to fit the wider Kar Kraft spindles that were unique to the Boss 429s [early Mustang discs had two-piece rotors/hubs]. The production spindle pin for the Mustang is around 4.5"...

    Disc Brake Conversion

    "Continental" or "Galaxie" big brake upgrade would be more accurate of a description, but definitely not "Cobra". '69/'70 T/A Boss 302s [the factory-prepped race cars for the Trans Am racing series] had the beefy 4-hole flange spindles with larger pins and the larger hole for the outer tie...

    Disc Brake Conversion

    Let me clarify some misinformation that has been stated in the above comment, in reference to the "Cobra" name, with respect to the '60s-era Mustang disc brakes. There has never been a disc brake system produced by Ford and installed on the '60s-era Mustangs that was referenced to as a...

    Disc Brake Conversion

    It would be great if everyone would "play nice", as you say, but Dan [Chockostang] chooses not to work well with others --and by others, meaning he doesn't like any form of competition that might possibly take a sale away from him. He purposely gives convoluted information out to make his...
