What is the difference between a brake booster and master cylinder?
What is the difference between a brake booster and master cylinder?
The engine will basically feed vacuum pressure inside the booster to improve the brake pedal feel. The brake pedal is connected to a power piston or push rod that is also connected to the center of the booster. The other end of the piston is directly connected to the master cylinder and governs a series of valves.
Do you need a proportioning valve for 4 wheel disc brakes?
A 4 wheel disc setup, the caliper sizes are supposed to dictate the proportioning the same way that a 4 wheel drum system does. NO proportioning valve is needed unless the rear calipers are too large.
Can you put disc brakes on a 1964 Chevelle?
You can bolt a master cylinder meant for a 1970 Corvette or 1976 GM truck right onto a 1964 Chevelle firewall. If you plan on drag racing, installing a roll control solenoid is a good idea.
Can a GM master cylinder be used on a Chevelle?
One of the nice things about a GM master cylinder, and an aftermarket one for these applications, is that the bolt pattern to attach it to the firewall and the brake pedal shaft hasn’t changed. You can bolt a master cylinder meant for a 1970 Corvette or 1976 GM truck right onto a 1964 Chevelle firewall.
Do you need to change master cylinder for disc brakes?
If you are changing the architecture of the system (from disc/drum to disc/disc, for example), you need to change the master accordingly. Often the the manufacturer of your rotors and calipers have a matched master cylinder. Some builders like to use late-model GM master cylinders, which generally have a metal bore and plastic reservoir.
How big are the brakes on a Chevelle?
For this Chevelle project, I’m installing a 14-inch, six-piston Baer Pro+ system on the front and a 13-inch version of the same system on the rear. The rear has an internal parking brake assembly with a mini-set of brake shoes that sit inside the hub part of the rotor.

Are there any brake upgrades for a Chevelle?
Luckily, there are more brake upgrade kits available for Chevelles than there were brake variations over the entire 1964–1972 run of these cars. Everything from very mild boltons to wild systems that rival that of a current ZR1 Corvette are available.
