Types of Vintage Master Cylinders
When you talk about classic car brakes and master cylinders you generally find two types. A single chamber design is when the car uses one fluid reservoir to supply brake pressure to all four wheels. A single reservoir master cylinder is often found on old vehicles that use four wheel drum brakes.
In the mid-60s manufacturers improved brake designs and reliability by adding disc brakes to the front. These cars used a dual chamber master cylinder. In this situation the smaller part of the reservoir feeds the wheel cylinders for the drum brakes. The larger chamber provides fluid for the front disc brake calipers.
This set up allowed the front and rear systems to act independently of each other. This enhanced safety, because if there was a hydraulic failure on the front brakes the driver could still use the rear ones to slow the …show more content…
Brake fluid should be a translucent honey or amber color. In a scenario where the primary seal is just starting to fail, drivers may notice that the brake pedal fades away from their foot and continues to the floor slowly as they try to hold the vehicle in a standing still position.
Repairing Old Master cylinders
Generally speaking, automobiles newer then 1967 will have a dual master cylinder. Cars built before this are often found with a single reservoir. Some of the more popular models like the [Ford Mustang offer conversion kits]. Installing these modified parts increases the performance, reliability and safety of the braking system.
Owners of collector cars are often faced with a tough decision. Should you [rebuild the original equipment] or locate a direct replacement?
