Hydraulic Brake Conversion Kits 1930 Ford


Brakes play an important role in stopping a car on time. Earlier in the late 20’s and 30’s traffic was not all the same as it is today and hence comparatively the brakes used were less efficient than the ones used today. Of late there have been a lot of modifications in them keeping in mind the traffic, terrain and the model of the vehicle.

No doubt brakes make an important part of a vehicle wherein the kinetic energy in converted into heat energy when there is friction in the wheel brakes. The recent braking system consists of a pedal and a booster assembly that is connected to a master cylinder and proportioning valve.

The target brakes were the first of the series of hydraulic brakes provided by Ford and the series started in the 1939 to 1948 model years. During that time Ford did not manufacture cars for the consumers and thus one can see that the production details are not given. The brakes provided in them were almost similar with the same 12” diameter and the width of drums extending to 1 ¾ which were larger than the model A brakes which were original. To upgrade into a hydraulic model it was important to round up a full set of brake backing plates, drums and hubs. In addition a cylinder and various hoses and fittings were needed. This resulted in use of different shoes but the end product was same.

The engine mount which is located on the side of the driver is said to provide double duty as a bracket for the clutch save cylinder. On conversion the slave cylinder needs to be held in place and all the dimensions measured to get a good fitting. The slave cylinder is then mounted to a plate with threaded holes so that nuts fit into it well and take a tight spot. The hydraulic design came into being for a change in the brakes wherein fluids were used instead of rods to actuate the brake shoes. This form required pedal effort so that the car can be stopped and at times even machine grinding to bring in correct fittings.
